+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+\f
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+\f
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+\f
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19yy name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+If you don't want to install development tools, and have access to the
+Web, you can get ROM images made on demand from http://rom-o-matic.net/
+
+The documentation tarballs should be extracted in the top directory (the
+one you are reading this INSTALL document from). A top directory called
+doc will be populated. This way the links from index.html will work
+properly.
+
+More likely if you are unfamiliar with Etherboot you should read the
+documentation starting with index.html if you have a Web browser, or
+doc/text/userman.txt (after installing the documentation tarball) if you
+just have a plain text terminal.
+
+Also read RELNOTES for any additional recent information.
+
+Don't forget to check out the contrib/ directory which contains much
+contributed software and documentation. Please contact the authors of
+those packages directly for queries.
+
+If you are booting FreeBSD, enable -DELF_IMAGE (and optionally
+-DAOUT_IMAGE) in Config. This should happen automatically now.
+
+The index.html file is the same as the one on the Etherboot home page at
+the time the distribution was made. Therefore some of the local file:/
+links from the Distribution section may not work.
+
+Etherboot was built using gcc 3.3.3 and binutils 2.15.91 from SuSE 9.2 but
+earlier 3.x versions will generally work.
--- /dev/null
+Major changes from 1.0 to 1.1
+
++ Everywhere: Can compile two versions of the code, under gcc or bcc
+(Bruce Evan's cc), so that 16-bit boot PROMs can be made. See
+netboot-16/README.16 for more details.
+
++ Everywhere: Removed duplicate defines, e.g. everybody defined their
+own ID for ethernet address size (6). Put IDs for magic numbers in
+various places. Still some inconsistency, ETH_ and ETHER_ are used.
+
++ Everywhere: Added prototypes of functions to netboot.h. Removed
+unused variables.
+
++ Makefiles: Rewritten.
+
++ netboot.h: Added define for TFTP_MAX_PACKET = 512. Increased TIMEOUT
+for tftp packets to 180 (about 10 seconds) so that tftp servers would
+be able to retransmit blocks.
+
++ main.c: Rewrote tftp(). Original was intended to get only one block
+and the strain on the structure due to modifications was showing.
+Increased config_buffer size to TFTP_MAX_PACKET+1 to avoid special
+casing data length=512.
+
++ linuxloader.c: Cleaned up the code in some places, especially
+linux_tftp. Moved the bootp reply block into bss space instead of a
+fixed location such as 0x90000.
+
++ ns8390.c: Removed one bug regarding packet length. packetlen was
+wrongly shortened when packets wraparound the ring buffer.
+
++ 3c509.c: Changed some of the gotos to returns. Removed ARP code since
+that's already done elsewhere. Removed interrupt enable and Rx early
+notification (we can't do anything with the packet until it's complete
+anyway).
+
+Major changes from 1.1 to 1.2
+
++ Small bug in makerom.c. Extra semicolon shortened for loop and made
+double checking code invalid.
+
++ Added version identification to startup string.
+
++ Gathered external declarations into netboot.h.
+
++ New compile time option for netboot-32. If INT19H is not defined,
+then boot ROM takes control as soon as BIOS scans it. This may solve
+the problem of some BIOSes not calling the boot ROM at INT19H. This
+may be when disks are detected by the BIOS, i.e. the machine is not
+truly diskless.
+
++ Added a new program, test.c, for making test ROMs to verify that
+the BIOS recognises the ROM.
+
++ New directory contrib contains contributed code. Currently contains
+masq by Gerd Knorr: make a boot floppy without DOS
+comboot-1.0 by Adam J. Richter: also make a boot floppy without DOS.
+
++ New mknbi-1.4 from Gero Kuhlmann and Markus Gutschke. This one handles
+the new bzImage format.
+
+Bumped up version to 2.0 because we are so listed in the Linux 2.0
+distribution and this would avoid confusion.
+
+Major changes from 2.0 to 2.1
+
++ Added LSM for transname-patch to contrib.
+
++ Added patch for serial console from Claus Heine
+<claus AT momo PERIOD math PERIOD rwth-aachen PERIOD de>.
+
++ Claus Heine contributed patches to the 2.0.21/22 kernel sources to
+allow NFS swap.
+
++ Markus Gutschke provided fixes to start2.S so that main can return to
+the ROM code if user doesn't want to ROM boot.
+
++ Added code to main.c to timeout on the prompt and assume Y or N
+for the answer. Timeout and answer configurable.
+
++ Made NE1/2000 probe addresses configurable from Makefile. Fixed up
+autoscan code.
+
++ Made NFS_BOOT a configurable option. By undefining it, only tagged
+file load is supported but ROMs are under 8k.
+
++ ROMSIZE is not used by makerom now. -s flag controls size of ROM
+at runtime. So don't need to recompile makerom if ROMSIZE changes.
+
++ Updated netboot-16 for the latest dev tools from the Linux-MT
+project. Use the size.c from there.
+
++ Got rid of _main() in main.c, instead using #ifdef ELF in start2.S.
+ELF is preferred now anyway.
+
++ Changed bcompare to standard bcmp and reversed sense of result.
+Reason: to use standard library if available, e.g. Netboot-16.
+
++ Common Makefile for 32 bit and 16 versions, with differences in
+Config files.
+
+Major changes from 2.1 to 2.2
+
++ New device driver for the Crystal Semiconductor CS89x0 chipset family.
+ (because of legal problems, this code is currently in the "contrib"
+ directory.)
+
++ Added support for loading BOOTP extension files (c.f. RFC1533).
+
++ If we have to go thru a gateway, then use the one that has been used for
+ the BOOTP daemon. If the BOOTP daemon is directly accessible, then use
+ the first entry in the "gw" gateway list instead.
+
++ For all retries, back off according to RFC951 by randomizing the timeouts
+ and exponentially increasing them until an average of one minute is
+ reached.
+
++ Warn if code will not fit into chosen ROM size. Happens only if the
+ autosizing in the Makefile somehow fails.
+
++ Modified the code for enabling the A20 gate; this could increase
+ compatibility, but I still have to hear from users.
+
++ The copyright message will now reflect, which features have been
+ enabled at compile time.
+
++ Added support for selecting different boot images from a menu. As a side
+ effect, this can be used to upgrade the ROM without having to burn a new
+ image (c.f. README.VendorTags).
+
++ Display a "message of the day" that is provided by the BOOTP daemon.
+
++ The sanity check for detecting a Linux kernel was too strong to properly
+ recognize a 2.1.x kernel; this has been fixed.
+
++ Trys to negotiate for 1432 octect blocks, if the TFTP daemon knows
+ about RFC1783.
+
++ We can optionally boot from local disk, if the BOOTP server cannot
+ be contacted.
+
++ Restructured directories: got rid of netboot-freebsd to reduce confusion
+ with Gero Kuhlmann's netboot, moved documentation to doc and renamed
+ directories to be more in line with Unix conventions. Edited documentation.
+
++ Created a dispatch table for NIC routines so that we can include one
+ or more drivers in one binary. Renamed all entry points in the driver
+ sources. Created two new files, config.c, which holds the dispatch
+ table and can be conditionally compiled; and nic.c which contains the
+ extern variables referenced by the drivers.
+
++ Automatically decide what size ROM is needed by doing a size and then
+ choosing the correct startup object. Currently caters for 8k, 16k and
+ 32k ROMs.
+
++ Optionally include a simple interpreter for ANSI escape sequences. This
+ allows for fancier boot menus.
+
++ Remove patches directory which is mostly relevant to 1.x kernels only.
+ Everybody should use 2.x kernels now. If for some reason you need those
+ patches, get an older release of etherboot.
+
++ Fix Makefile to work even if . not on PATH.
+
++ Sadly, 32 bit ROMs are now > 8kb. We will try to reduce the size by
+ conditionals in a later release. For now, use version 2.1 if your NIC
+ won't take > 8kb ROMs.
+
++ Release as 3.0b1 because of the large amount of changes.
+
++ Fixed a few problems with the code for ANSI escape sequences and
+ added optional support for displaying graphics.
+
++ Optional support for password protected boot images.
+
++ Optional support for booting from block devices (floppy, hd).
+
++ The bootp server can pass additional parameters to the loaded kernel
+ image (currently, this only applies to Linux) and the user can be
+ allowed to edit a commandline; the latter is optionally protected by
+ a password scheme.
+
++ Set the warm-boot flag when the main routine is entered.
+
++ Release as 3.0b2
+
++ Added code for updating the FlashCard EPROM over the network
+ (contrib/flashimg).
+
++ Added very simple code for turning a ROM image into a network loadable image.
+ This is useful for debugging, but some users without flash EPROMs might
+ appreciate the possibility to load a fully fledged image from a very basic
+ configuration.
+
++ Optional support for compressing the ROM images. Please read
+ doc/COPYING.compressor before using this feature.
+
++ Sync'd our source tree with Gero's netboot-0.5; this means that you now need
+ the as86 from the ELKs project in order to recompile all of the files. This
+ should not affect normal usage, though.
+
++ Added "mknbi-blkdev" for booting from local block devices.
+
++ Fixed some bugs in ppmtoansi.c and bootmenu.c
+
++ Renamed reference compressor implementation to compressor.exp otherwise
+ make tries to use it and it should not be turned on by default.
+
++ Zero'ing BSS in 16-bit version has to be done to _end, not to A0000
+ because it's executing in a segment, not in flat address space in 16
+ bit mode.
+
++ Ken Yap contributed a quick and dirty Perl script for people who use
+ netboot to test ELKS. So far I'm the only one I know of; maybe the
+ others are silent. :-(
+
++ Release as 3.0
+
+Major changes from 3.0 to 3.1
+
++ 4 versions of etherboot can be built for a NIC: .com for testing and
+ .rom for burning into EPROM, and corresponding compressed versions:
+ .lzcom and .lzrom.
+
++ The loaders are now separate programs which are prepended to the
+ etherboot binary. This allows them (plain and uncompressing versions) to
+ be maintained separately and gives a bit more RAM to the etherboot code.
+
++ No need to define ROMSIZE in the build. makerom automatically discovers
+ the ROM size needed and fills in the size field in the ROM. This
+ simplifies the build procedure.
+
++ 16 bit versions use the same loaders as the 32 bit version. Also fixed
+ two bugs in the 16 bit versions: (1) a non-8086 instruction in zloader,
+ (2) setting warm-boot flag in main which zapped some code.
+
++ Fixed a documentation bug on the ANSI escape sequences.
+
++ Include netboot-0.5.3 distribution from Gero Kuhlmann.
+
++ Included some contributions from Dickon.Reed AT cl PERIOD cam PERIOD
+ac PERIOD uk: Running display of Kbytes loaded, line of delimiters after
+loading complete, a temporary hack to address timing problems with the
+3C509, and some Makefile cleanup. The first two changes need to be
+enabled in Config with defines.
+
++ mknbi-blkdev seems to have been left out by Gero Kuhlmann. Add to
+ contrib directory. You probably have to make a symlink to it from
+ the netboot-0.5.2 directory.
+
++ Release as 3.1
+
+Major changes from 3.1 to 3.2
+
++ 16 bit version now can load to extended memory, if it exists. On
+ a 8086/8 this will silently fail.
+
++ Cleaned up interface between main body of code and NIC drivers. No
+ global variables referenced in NIC driver, everything is passed
+ through a structure. Only the probe function is visible outside,
+ pointers to the others are returned in the structure.
+
++ Implemented autoprobe for 3c503. Also simplifies code at same time.
+
++ Removed ARP response code in ns8390.c. Don't think we need to respond
+ to ARP requests because other machines will do gratuituous ARP when
+ boot code sends out bootp request. Are there cases where this is not
+ true? Gateways?
+
++ Added 1 second timeout to routine that clears the keyboard buffer
+ in case there is no keyboard.
+
++ Added a skeleton driver that can be used as a template for new NIC
+ drivers.
+
++ ./lzhuf in Makefile so that it will run even if . is not on path.
+
++ Fixed comboot to work on 286s also. Won't work yet on 8086/8.
+
++ Fixed mknbi-blkdev to configure properly under netboot-0.7.
+
++ Added David Munro's PCI code adapted from Linux. Currently has entries
+ for PCI NE2000 clones. Generalised it to probe other PCI cards later on.
+
++ Moved twiddle() outside NIC driver except where used to provide a delay.
+
++ Fixed bug in Makefile spotted by Ton Biegstraaten. Should prepend
+ ZLOADER to make all.lzcom, not LOADER.
+
++ Charlie Brady donated a NE2100 (LANCE) card, so Ken Yap wrote a driver
+ for it. Should work for other LANCE (7990, etc) based cards with some
+ modifications.
+
++ Markus Gutschke wrote rom-scan, and it is in contrib/.
+
++ Hack rom-scan.c so that a DOS version can be compiled.
+
++ Removed all.* targets from Makefile. The NIC specific loaders should be
+ used in preference as the all.* loaders can run out of memory.
+
++ Added a disable routine to dispatch table so that cards can be turned
+ off before the loaded code is executed.
+
++ Make INT19H the default.
+
++ Rogier Wolff persuaded AW computer systems to contribute the Intel
+ EtherExpressPro 100 driver. The binary to hex converter in contrib/
+ is also from Rogier Wolff. Part of the work is sponsored by BitWizard
+ NL (www.bitwizard.nl).
+
++ Distribute with a subset of netboot-0.7.2 that doesn't have the bootrom
+ portion.
+
++ Release as 3.2.
+
+Major changes from 3.2 to 4.0
+
++ Merged in Vlad Lungu's patches for DHCP support, ifdef'ed by DHCP_SUPPORT.
+
++ XID matching fix also provided by Vlad Lungu.
+
++ Merged in William Arbaugh's patches to make eepro driver work properly.
+
++ Add to contrib/ better bin2intelhex from Jean Marc Lacroix.
+
++ Patches from Jim Hague (thanks!) for the following:
+
+* Added PIO mode for 3c503 to ns8390.c. Changed the card detection to
+ detect shared memory or PIO and use the selected one, and removed
+ a jumper check that failed on the Bull (no jumpers).
+
+* Added more #ifdefs to ns8390.c to include only code relevant to the
+ card being compiled, and removed unnecessary run-time card vendor
+ behaviour branches - it's all now #ifdefd.
+
+* Added a -3 parameter to makerom to set the last two bytes to 0x80.
+ These are the values they have in the 3Com Etherboot image that was
+ in the Bull. (Also on the 3c503 card I have - Ken.) Also altered the
+ Makefile to add this parameter when building a 3c503 image.
+
+* Modifies lzhuf.c, objdump86.c & size86.c to work on either-endian systems.
+
+* Adds a -DT503_AUI config paramter to let you choose AUI or BNC on
+ 3c503s. Previously it defaulted to AUI, and you had to change the
+ code to alter it.
+
+* Changed the BCC include directory to /usr/bcc/include. If you use the
+ BCC include files they don't define u_char, u_short etc. I've added
+ these into linuxdef.h, ifdef'd on BCC.
+
+* Adds a trivial Linux 3c503 driver patch to the contrib directory
+ to let it spot these 'ere Bull things.
+
++ Charlie Brady confirmed that the Lance driver works with PCI so there
+is a new lancepci driver now.
+
++ Removed support for NFS_BOOT; only TFTP booting supported now.
+
++ Removed support for linear images; only tagged images supported now.
+
++ Removed PRIORIZEBOOTPKERNEL and BOOTPKERNELONLY. Bootp reply must
+specify kernel name.
+
++ Bug fix for 16 bit version of 3c509 driver: sign bit propagation bug.
+
++ Revert to non-pausing versions of out[bw] and inb for NEx000 driver
+because of reports of timimg problems on some cards.
+
++ New driver for NI6510. Just a simple tweak of the lance driver for
+different ID bytes and different register offsets. According to the
+NI6510 driver in Linux, the NI6510 Etherblaster is more like the NE2100
+and would be detected by the NE2100 driver. So use that one instead.
+
++ New drivers for 3c507 and NI5210, both of which use the i82586 chip. It
+works properly for both now. I needed to have enough receive buffers to
+make sure i82586 never goes into an out of resources state. 3c507 driver
+has one quirk, it only responds after second bootp request. I seem to
+remember something about this problem of losing the first packet after
+initialisation in early Linux discussions. I am also now convinced
+that Intel designers have weird minds. BTW, NI5210 driver assumes 8k
+RAM because if you put the ROM on the NIC you can only have 8k RAM. If
+you are putting the ROM off-board and you want 16k, well, talk to me.
+
++ Call nic_disable routine just before jumping to loaded image. This
+does nothing in most drivers, but may have side effects as the nic_reset
+routine used to be called instead.
+
++ One of those "why I didn't think of it before" ideas: A modified version
+of comboot, called floppyload, that is prepended to the .rom image rather
+than the .com image and then both written raw to a floppy for testing the
+bootrom. All we have to do is jump to an entry point in (z)loader that
+skips the INT19H stuff. Relocation will happen automatically. Now the
+.com images and comboot are superfluous, unless one is masochistic enough
+to want to try to test under DOS.
+
+Added .fd0 targets to Makefile. Saying make <card>.fd0 will make
+floppyload.bin and <card>.rom, and cat both to /dev/fd0. Naturally the
+drive must be writable and you must have a floppy in the drive.
+
++ New driver for Tiara (Fujitsu EtherStar). This was one of the easiest
+drivers to write. But the chip apparently has some quirks; there is no
+Linux driver for it in the standard distribution and the email address
+of someone who wrote an alpha driver is invalid. Perhaps I'll bump into
+an AT1700 (which has a similar chip) one day and be able to reuse a lot
+of the code.
+
++ Updated contrib/mkelksnbi for ELKS 0.0.68.
+
++ Confirmed that the SMC8216 driver works. 8416 not tested, it's a PnP
+card. Can anybody confirm this?
+
++ New contributed software: p910nd, a tiny printer daemon suitable for
+diskless hosts.
+
++ Made ANSIESC work for Etherboot/16.
+
++ Fixed Makefile and Config.* so that it works with old binutils.
+
++ Included a subset of netboot-0.7.3.
+
++ Released as version 4.0.
+
+Changes between 4.0 and 4.1
+
++ Patches by Andrew Coulthurst for eepro100b.
+
++ Patches by Doug Ambrisko for booting Windows95 after answering N to
+the boot from network question. Added conditional code to cope with
+broken DHCP server and TAG 128.
+
++ Put version and driver identifier at end of ROM image if it fits,
+to help identify ROMs in future.
+
++ Capture ROM segment address and length to help choose between multiple
+NICs later.
+
++ Don't clear all of memory because it will destroy return address
+on stack.
+
++ Changes to comboot-1.2 (although obsolete) to run on 8088s.
+
++ New version 0.2 of p910nd, a non-spooling printer daemon.
+
++ Patches by Alex Harin to prepended loaders and makerom to generate PnP
+ready ROMs. Modified makerom to automatically detect PnP and PCI headers
+and do the right thing. Added option to change the vendor and device IDs.
+
++ Augmented documentation for 2.1 and above kernels. Kernel now wants to
+mount /tftpboot/<hostname in bootptab> rather than /tftpboot/<ip address>
+as the root FS.
+
++ Changed all the outb* and outw calls in drivers (except eepro) to be
+OUTB* and OUTW, then defined macros to translate to out[bp]* for both
+Etherboot/32 and Etherboot/16, instead of pasting macros from Linux
+include files because apparently they've changed in 2.1. At the same
+time reversed the arguments in start16.S for outb and outw to match the
+Linux convention. Unfortunately the out[bw] usage came that way from
+FreeBSD. Someday I'll reverse the arguments in the C files properly.
+For any new driver writers, you should use the Linux order now.
+
++ New contributed utility, disnbi for decoding and extracting network
+boot images.
+
++ Martin Atkins contributed mntnbi for mounting DOS NBIs.
+
++ Peter Dobcsanyi contributed vendor and device IDs for the Netvin
+NE2000/PCI clone.
+
++ adam AT mudlist PERIOD eorbit PERIOD net contributed RARP code as
+alternative to BOOTP/DHCP. Activated by RARP_NOT_BOOTP define.
+
++ Added link to Claus-Justus Heine's NFS swap Web page and updated the
+contrib directory.
+
++ Disabled max packet length check in ns8390.c. Caused spurious Bogus
+packet messages in some cases and doesn't seem that useful a sanity
+check anyway.
+
++ Daniel Engstrom contributed a SMC9000 driver.
+
++ Didier Poirot contributed an Etherpower II (EPIC 100) driver.
+
++ Added bug fix by Attila Bogár for bootmenu.c and patch to main.c to
+remove looping menus on failure. Also code for ARP replies and TFTP
+block retransmit (#ifdefed because controversial).
+
++ Code cleanup of tftp and tftpd also by Attila Bogár.
+
++ Nathan R. Neulinger fixed a bug with block being declared short instead
+of u_short in tftpd.c, which limited transfers to 32k blocks. Fixed
+problem with field tu_block being declared as signed short in many
+platforms by including fixed version of tftp.h. Fixed tftp also for
+good measure.
+
++ New mini-HOWTO on a "ssh terminal".
+
++ Andreas Mack pointed out that eepro100 doesn't compile on 2.1 and
+2.2 kernels. Removed unnecessary include of bios32.h and reliance on
+definition of virt_to_bus in kernel headers in eepro100.c, epic100.c
+and lance.c.
+
++ David Sharp contributed a Tulip driver written for FreeBSD netboot.
+Ken Yap ported to Etherboot. Not tested yet because no hardware.
+
++ Replaced references to arptable[ARP_CLIENT].node to nic->node_addr in
+eepro100.c and epic100.c as they should be.
+
++ Greg Beeley of LightSys Technology Services contributed a 3c905b
+driver. Be sure to read the release notes in 3c905b.txt.
+
++ Günter Knauf suggested making the prompt strings more generic and to
+put a newline after the answer. Beware, N now means Network boot and
+not No to network boot.
+
++ Alex Nemirovsky contributed some patches for BIOSes that use an extended
+space at the top of 640k. Also some code for BIOSes that don't implement
+BIOS32 correctly or at all.
+
++ Use PCI extension BIOS header only for PCI cards, all others use legacy
+extension BIOS header.
+
++ Klaus Espenlaub contributed various cleanup patches to the code. Also
+introduced Rainer Bawidamann's code, see next paragraph.
+
++ Rainer Bawidamann contributed a Realtek 8139 driver.
+
++ Simplified rules for building .bin files, use -b of as86 so we
+don't need ld86 or objdump86 now. But later found that a fixed as86 is
+required. So supply preassembled binaries. The keen hackers can get the
+fixed tools.
+
++ Georg Baum contributed a Schneider & Koch G16 driver. Only the
+32 bit version works at the moment; even though the 16 bit version
+compiles, it won't work because the current code assumes flat memory
+addressing. Anybody who needs the 16 bit version should feel free to
+fix it.
+
++ Reduce size of ROM image loaded by floppyboot.bin from 64kB to 32kB
+for a slight speedup in loading. None of the images are even 32kB anyway.
+
++ Updated some of the documents in doc/sgml.
+
++ Klaus Espenlaub sent in a totally revamped start32.S, using the code16
+and code32 directives in recent GNU as (so if this file won't assemble
+maybe your as version is not recent enough). Also patches to the menu
+handling code.
+
++ jluke AT deakin PERIOD edu PERIOD au sent in a fix for the WD/SMC8013
+long ago which I finally got around to verifying.
+
++ start16.o and start32.o are supplied for those people who have problems
+compiling start*.S with as/as86.
+
+Released as Etherboot-4.2.0
+
++ One line fix to 3c509b by Greg Beeley for Wake-On-LAN support.
+
++ Added patches by Klaus Espenlaub that I forgot.
+
++ Made AS_PSEUDOS not the default, assume that people have sufficiently
+up-to-date GNU as. If not they can uncomment that line.
+
+Released as Etherboot-4.2.1
+
++ Disable 3c509 after loading finished or port may be unusable.
+
++ Woops, forgot to up the version's last digit in the last release.
+
++ Stephan Bauer sent in a device ID for config.c for 21142 chip Tulips.
+
++ Ifdef out input overrun recovery code (it's really only needed for
+NE2000s) and use SHMEM by default for 3c503s to bring the ROM size down
+below 8kB.
+
++ Added code to start32.S to detect < 386 and exit so it doesn't hang
+the computer. Doesn't print a message yet.
+
++ Changed README.sgml to recommend that TFTP use a separate directory
+from NFS, /tftpdir. Added sample configuration file for DHCPD and caveat
+about the name of the root directory when using DHCPD.
+
++ Revamped atnetboot.sgml: use mtools most of the time, write about a
+few example applications.
+
++ Quick Perl script for converting bootptab to dhcpd.conf.
+
+Released as Etherboot-4.2.2
+
++ Forgot to put new version of src/start32.o. Not urgent though, the
+extra code only guards against Etherboot/32 being executed on < 386.
+
++ Supply version preassembled start32.o with ANSIESC and FLOPPY defined
+for those with a deficient as. Define dummy handleansi routine in
+ansiesc.c so that it will still link even if this start32.o is used.
+
++ Edited *.asm so that they can be assembled by either as86 (ELKS version)
+or nasm.
+
++ Changed Makefile so that one can choose between no as86, as86 or nasm.
+
++ Added Mark Burazin's conditional code for Compex RL2000 PCI NIC.
+
++ Increase delay during probe phase to 10ms as 1ms is too low for some
+3c509 boards. Donald Becker's Linux driver hints that > 2ms is needed
+to be safe. Also call t509_disable in case board was active.
+
++ Update README.sgml date and version.
+
+Released as Etherboot 4.2.3.
+
++ rtl8139.c: Reduce the number of transmit buffers to reduce footprint.
+Remove polling loop in *_loop(), caller already does the looping.
+
++ main.c: Fix code indentation in bootp().
+
++ Small corrections to documentation.
+
+Released as Etherboot 4.2.4.
+
++ Matthias Meixner found a longstanding bug in rtl8139.c where it was
+testing the wrong bit for the existence of a packet in the buffer.
+
++ Added paragraph to documentation about caveats for hosting NFS root
+on a different architecture.
+
+Released as Etherboot 4.2.5.
+
++ Updated mklnim for RH6.0 which uses a different floppy image and
+requires 'network' to be appended to kernel parameters.
+
++ Reversed sense of #ifdef DHCP_SUPPORT to #ifndef NO_DHCP_SUPPORT and
+so forth, i.e. the default is with DHCP support.
+
++ Suggest reducing options for rtl8139 driver to minimise footprint in
+release notes.
+
++ Jim McQuillan provided changes to support the SMC1211, which uses the
+RTL8139 chip.
+
++ Changed lret in start32.S to int $0x19 so that it doesn't depend on
+the return location being there.
+
+Released as Etherboot 4.2.6
+
++ Succeeded in booting FreeDOS with the kernel in the tagged image rather
+than on the ramdisk, i.e. the boot process jumps directly to the kernel
+in memory. The utility is mkfreedosnbi in contrib/.
+
++ Additions to the documentation.
+
+Released as Etherboot 4.2.7
+
++ Matt Hortman pointed out that the BIOS clock value returned by INT1AH
+rolls over at midnight, causing delay loops that cross midnight to
+fail. Fix was to keep track of midnight crossings in currticks so that
+currticks' return value is monotonically increasing.
+
++ Added paragraph to documentation about editing PCI vendor and device
+IDs in Makefile if needed.
+
++ Merged in FreeBSD support code supplied by Doug Ambrisko. Thanks!
+
+Released as Etherboot 4.2.8
+
++ Cleaned up the FreeBSD support in osloader.c. Symbols to use in Config
+are to select image type, not FreeBSD specific now.
+
++ Added simple signature checking code in floppyload.asm in case somebody
+forgets to append a ROM image or tries to load a non-ROM image.
+
++ Merged in 3c90x and multiple PCI bus support by Steve Smith. Thanks!
+
++ Included NT-Diskless-Terminal HOWTO by Pavel Tkatchouk.
+
++ Included snapshot of H. Peter Anvin's rewrite of tftp.
+
++ Combined tftp and tftpd directories, and touched up Makefile to reflect
+normal Linux install directories.
+
+Released as Etherboot 4.2.9
+
++ NT-Diskless-Terminal HOWTO renamed to Diskless-From-NT.
+
++ One line fix to mknbi-dos to recognise FAT16 filesystems as legal.
+Updated first.S in mknbi-dos so that it can be assembled by nasm and is
+also suitable for FreeDOS with the right define. Still backward compatible
+with as86. Bug fix at line starting getnm3:.
+
++ Updated first.S in mknbi-linux so that it can be assembled by nasm also.
+
++ Locate bootp data block at 0x93C00-0x93FFF to free up 1024+ bytes in
+[0x98000-0x9FFFF]. Etherboot/32 only, business as usual for Etherboot/16.
+
++ Patch from Attila Bogár to make CONGESTED a compile option for
+TFTP_TIMEOUT. Also corrected spelling of his name in README.
+
++ Fixed start32.S to assemble correctly with gas version 2.95. Must
+define GAS295 in CFLAGS.
+
++ Add contrib/3c90xutil containing a utility for handling 3c90x EEPROMs
+in situ.
+
++ Update p910nd to 0.3. client.pl now checks if hostname is known and
+uses more convenient routines from Socket module.
+
++ Moved the Flashcard directory into a separate package as it's of
+limited interest.
+
+Released as Etherboot 4.2.10
+
++ Fixed bug introduced in 4.2.10 in code for handling bootp extension
+files.
+
++ Change in 3c90x.c so that it can compile under FreeBSD.
+
++ Patch to tulip.c from Nick Lopez to handle Macronix 98715 (Tulip clone).
+
+Released as Etherboot 4.2.11
+
++ Prefer RFC1533_GATEWAY to giaddr for routing tftp packets.
+
++ Print out both relay address and gateway address.
+
++ Stored arptable ipaddrs in network byte order. Makes everything simpler
+and we can get rid of convert_ipaddr. Now %I in printf and inet_ntoa
+have to deal with NBO. We reduce the footprint by ~100 bytes.
+
++ Renamed setip to more standard inet_ntoa and change argument type to
+suit, using in_addr.
+
++ Replaced bcmp by memcmp, bzero by memset, and bcopy by memcpy. Allows
+us to use optimised versions in inline assembler.
+
++ Replaced OUTB and OUTW by outb and outw with arguments reversed.
+Finally all the out macros are the same form as for Linux.
+
++ Replaced \r\n and \n\r in output strings with \n since putchar
+now prints \r before \n. Then changed printf("\n") to putchar('\n').
+Like Unix convention for strings now.
+
++ Got rid of test.c and Makefile rules connected with it.
+
++ Added patch to eepro100.c by Matt Hortman to correct PCI latency.
+
++ Merged in Marty Connor's ntulip.c. Now supports Macronix 98715 and
+Linksys LNE100TX.
+
+Released as Etherboot 4.2.12
+
++ Anders Larsen contributed mkQNXnbi, for generating tagged images from
+QNX kernels.
+
++ Bernd Wiebelt contributed code to request vendor tags in DHCP.
+
++ Fixed more bugs introduced in 4.2.10 in code for handling bootp
+extension files.
+
+Released as Etherboot 4.2.13
+
++ Marty Connor reduced RTL8139 footprint by using only one transmit
+buffer instead of 4. Now RTL8139 is reliable.
+
++ Moved initialised data declaration from ns8390.h to ns8390.c.
+
++ Contributed utilities for wake-on-LAN: wol.c (Bob Edwards) and wake.pl.
+
++ Makefile for 3c90xutil/romutil.c. -O is essential when compiling.

++ hwilmer AT gmx PERIOD de found a probe error in 3c507.c, shouldn't
+mask memory size with 0xffffL, this fails with 64kB memory. Also
+changed to use real-time-clock to timeout on initialisation of i82586
+rather than relying on decrementing a variable (which is CPU speed
+dependent).
+
++ James Pearson pointed out that ~ should be escaped as ˜ in
+vendortags.sgml. Also cleaned up the 8-bit characters while I was at it.
+
++ Günter Knauf pointed out that if ASK_BOOT is defined, then key input
+echos twice. Also, CR doesn't select the default. Problem was that getchar
+converts all \r to \n then main.c was testing against \r instead of \n,
+and also that getchar() was echoing when it should leave it to the caller.
+Deleted code from getchar() and made it a function with no arguments.
+Also sent me a new version of mp-form.pl with mp-form.txt. Also suggested
+the good idea that the gateway and relay fields not be displayed if they
+are not used.
+
++ Bob Edwards sent in patches to ntulip.c to autodetect 100 Mb media

+
++ Okuji Yoshinori found a small bug in main.c: for (retry1 = 0; retry < ..
+Don't know what effect it had.

+
++ FUKUHARA Makoto supplied a patch for 4.4.4 for FreeBSD ELF booting
+with large tftp blocks which I missed putting in.
+
++ Small patch by Marty Connor to tulip.c to handle fast Tulips better.
+
++ Wrote small loader to load images from .com files.
+
++ Shusuke Nisiyama contributed a 3c595 (and may work for 3c590) driver.
+
+Released as Etherboot 4.4.5
+
+A major reorganisation by Klaus Espenlaub. Here are his notes, verbatim:
+
+The biggest change is the almost rewritten Makefiles (both in src and in
+doc - the one in doc is still reasonably simple). If you want to get
+an overview - basically one Makefile now builds both /16 and /32 ROMs.
+This involves quite a few make variables (similarly in Config), but it
+should be mostly self-explaining. I also converted the suffix rules to
+pattern rules, because it is the only way to keep the build directories
+for /16 and /32 apart.
+
+Generally all /32 code is compiled in bin32, all /16 code is compiled
+in bin16, and the code that works for both is in bin.
+
+The names (object files, images, but NOT the final ROMs) used during
+the build process for some PCI cards have changed (especially lancepci
+and nepci).
+
+I eliminated the driver.a file by adding yet more ugly code to genrules.pl
+(no, I'm not very proud of the code I added there - I hate perl, but
+at least it works), which now generates all sorts of make rules and
+dependency information. This eliminates the redundant recompile of all
+other drivers if you specified a specific target at the make command line.
+
+There are now automatic checks for the generated ROM size (3K safety
+margin are used to allow for 1K BIOS EBDA and 2K stack). This should
+avoid most of the cases in which the stack overwrites code and/or data,
+causing strange crashes.
+
+On to the real code - I rewrote both the ELF and a.out loading (the
+blocksize is now properly handled for all formats), and now most of the
+code is identical. Someone might want to merge the two. I verified that
+both a.out and ELF FreeBSD loading still works by booting the FreeBSD
+2.2.8 and 3.4 install kernels (the ELF kernel you gave me didn't work
+for whatever reason). Actually I tested everything except NBI, but that
+code is completely unchanged.
+
+I eliminated config.h and created cards.h - just have a look and you
+should get the idea. The PCI/ISA prototype matching hack is now buried
+in there. All PCI drivers (and skel.c) have been converted to the new
+include file.
+
+The only file that is really new is nfs.c, which contains the code where
+I started my journey.
+
+The loader code is now merged into one file for both the normal and
+compressed case. Some bugs have been fixed along the way (the normal
+loader copied too much data, potentially crashing the machine). BTW: I
+removed the block copy from comboot, because the first thing the loader
+code does is - to copy the code to the right place. Also copying it to
+0x80000 prevents compressed ROMs (though there is no way in the Makefile
+to create such a beast). Also the stack changing code was wrong -
+the overflow handling is missing: 0x9fxxxx-0x800000 is truncated to
+fit in the 16 bit register, which is not quite what one would expect.
+The stack pointer must be in the same segment, so for overflows just
+load 0. Anyway, we don't need a new stack for 4 bytes (the return
+address). Also the shifts won't work on an 8086/8088. The ROM segment
+and length code is also done once more in loader.S. Finally the org
+0x100 didn't work with my version of as86 - it prepended 256 null bytes.
+Don't get me wrong - I see that comboot was just a quick and dirty hack.
+It's now working...
+
+I also fixed floppyload to read exactly the right amount of data (not
+up to 65520 bytes more like the Linux code did) and ripped out some
+unused code.

+
+lzhuf.c was modified not to output ':' characters, because I find it
+useful to search for them in a make log to spot all error messages.
+
+Finally all symlinks have gone
+
+I fixed sgml/vendortags.sgml (maybe it's more a workaround): sgml2txt
+didn't like the ~~' sequence and ignored a whole line, making the .txt
+file incomplete. Also freebsd.txt was converted to sgml.
+
+My standard patch to netboot-0.8.1/configure (to remove the "unknown") is
+again in place - how is this file created? By hand? I added serial/dual
+console support to mknbi-linux.
+
+Oh, and something I almost forgot: Etherboot now works under VMware.
+VMware has a rather large EBDA (3K instead of 1K like most other
+BIOS versions), so one might have to sacrifice a few nifty options.
+Note that the Makefile check cannot detect this - maybe we should add a
+runtime check, too? One thing that doesn't work with VMware is the "Boot
+Local" stuff - it's not terribly useful if you have to boot from disk,
+but it shouldn't crash the machine (I've seen several triple faults,
+depending on RELOCADDR and the stack usage). I tracked it down to the
+fact that VMware crashes on int 0x19 if the memory area 0x98000-0x9f3ff
+is overwritten. If one changes RELOCADDR to 0x8f000, everything works
+nicely. Someone should report the bug to VMware. Also proper boot ROM
+support should be added to VMware and they should upgrade the virtual
+card to 100Mbps (don't laugh - they limit the bandwidth to 10Mbps even
+if you have a real 100Mbps card!). Maybe one could even use the flash
+utility for the recent AMD PCnet cards...

+
++ Vsevolod Sipakoff suggested that the probe address list for NE2000
+should match that of Linux. Done, with the deletion of 0x360 which often
+conflicts with the parallel port at 0x378.
+
++ Created mknbi, a Perl utility that replaces mknbi-dos, mknbi-linux,
+mkfreedosnbi, and mkromnbi. Removed mk{freedos,rom,elks}nbi/ from

+
++ Christoph Plattner found that the 16 bit bus width fix for NEPCI cards
+introduced in 4.5.6 breaks operation for other NEPCI cards. So now the
+#define symbol is NS8390_FORCE_16BIT, to be used when the NIC requires
+16 bit bus width but Etherboot guesses wrong. This needs to be fixed
+later to autodetect adapter bus width.

+
++ Jim McQuillan sent in modifications to tulip.c to reject bad packets.
+
++ Klaus Espenlaub suggested changing the filename substition macro in the

+Released as Etherboot 4.7.6 (developmental)
+
++ All the changes from 4.6.5 to 4.6.6 back propagated except for the

+
++ Removed -nostdlib from ld flags. Seems to be a vestige from when we

+
+Released as Etherboot 4.6.6
+
++ Contributed one-line patch to allow booting from SCSI disks also (sd).

++ Grzegorz Jablonski sent in a fix for long-standing bug in loader.S that

+
++ More updates to documentation.
+
+Released as Etherboot 4.6.7
+
++ Rick Kennell pointed out that there is another place in main.c where
+the DHCP request is sent with a source port of 0, which may not elicit
+replies from some DHCP servers or pass gateways. Changed to
+BOOTP_CLIENT.
+
++ Depca driver finally works.
+
++ Changed unsigned int len; to int len; in 3c595.c transmit routine
+which was generating a warning from gcc.
+
++ Removed warning about ljmp indirect without * in start32.S by putting
+in the *. Checked that generated code has not changed by comparing
+binaries. Later: But only for gas 2.9.5 and above, gas 2.9.1 doesn't
+like *.
+
++ Wanted to do the same for the lcall's in pci.c but discovered that
+gas 2.9.1 chokes on *, and as I don't want to introduce more #ifdefs
+into pci.c, we'll just live with the warnings until gas 2.9.1 is dead
+or the incorrect syntax is rejected by a current gas release.
+
++ Reversed #define so that GAS291 indicates gas 2.9.1. Rationale: gas
+2.10 probably behaves like gas 2.9.5 so the default should be the new
+behaviour.
+
++ NI5010 driver finally works. Weird NIC, has only 2kB memory on board
+so if you don't switch to the receiver immediately after transmitting
+you will lose the reply packet. (This is a very ancient board, I was
+doing the driver for kicks.)
+
++ Implemented a low-overhead timer routine for implementing timeouts in
+drivers. This timer should be used instead of hacks with integer loops
+(which are CPU speed dependent) or calling currticks(), which has
+relatively high overhead because it reads the BIOS timer, and has a
+resolution of only 1/18th of a second. Timer 2 of the 8254 timer chip
+can be loaded with an unsigned 16-bit value that will be decremented at
+about 1193 counts per ms (constant TICKS_PER_MS in timer.h). So the
+maximum timeout that can be implemented with a single call is about 54
+ms. Call load_timer(u16) to load and start the timer (0 == 65536). Call
+int timer2_running() to check if it is still active. timer2_running can
+be interleaved with other tests, e.g. on the NIC hardware registers.
+When the timer runs down to 0, it will return 0. If you just need to
+delay a short time, call waiton_timer2(u16) to load and delay that many
+ticks.
+
++ Removed slowdownio() from sources. It's called in only one place and
+is followed by a call to currticks() which will result in a large delay
+anyway. It's also not clear if the strategy in slowdownio (a couple of
+local jumps) will even work on fast CPUs with instruction caches.
+
++ Removed support for %i (alias for %d) in printf. Nobody uses it, if
+they do they should just edit the format string to use %d, and removing
+it means one less non-standard format in printf; we have %X, %b and %I
+as it is.
+
++ Simplified currticks() by accessing BIOS variables directly instead of
+calling timeofday BIOS interrupt.
+
+Released as Etherboot 4.6.8
+
++ I'm pissed off with the inconsistency between gas 2.9.1 and gas 2.9.5
+re ljmp * (indirect jump). Some assemblers claiming to be 2.9.5 dislike
+the * (RH6.2's is one). I'm going to just make it ljmp and live with the
+warning message until the gas 2.9.1 syntax is totally dead.
+
++ Various fixes from Klaus Espenlaub: Fix for NFS booting from *BSD
+platforms, fix for Lance driver, interrupt was being turned on, fix for
+serial.S and code cleanups.
+
++ Paul Robertson of Locsoft found that if the top half of %esp contains
+garbage just before the first call to real_to_prot in start32.S, it can
+affect booting on some BIOSes. Inserted andl to clear top half.
+
++ Sleep for 2 seconds after failure to load file to avoid pounding the
+server if the file does not exist and thus shutting down the tftp
+service (inetd has rather poor rate controls).
+
++ Shredda of gmx.de reported a discrepancy between the Macronix MX98715
+device IDs used in pci.h and NIC. Marty Connor has ruled that the id in
+NIC is a typo. If booting works from floppy but not from ROM, this may
+be the reason.
+
+Released as Etherboot 4.6.9
+
++ Oops, a brown paper bag bug in start32.S. Forgot that the currticks()
+needs interrupts enabled to work. Calling the BIOS allowed interrupts to
+happen by going into real mode (interrupts are disabled in protected
+mode). So inserted prot_to_real and real_to_prot pair inside
+currticks().
+
+Released as Etherboot 4.6.10
+
++ Marty Connor and Gary Byers of thinguin.org contributed a LILO prefix
+file that makes the Etherboot image look like a Linux kernel to LILO and
+thus bootable from the LILO prompt.
+
++ Ifdefed out code in mknbi that falls back to the tftp directory for
+root-path. The result is that the options passed to the kernel specifies
+the tftp directory as nfsroot even if there is no root-path option in
+the DHCP or BOOT server configuration. This interacts badly with recent
+Linux kernels which actually pay attention to the root-path handed down
+and use that as nfsroot. People who were expecting the diskless kernel
+to use the default /tftpboot/<name of client> as nfsroot would have been
+surprised to find it trying to use the tftp directory (which often
+happens to be /tftpboot, although I recommend that it be different, to
+improve security).
+
++ Eric Biederman found an off-by-one bug in the ELF loader.
+
++ Christoph Plattner pointed out that the comments for COMCONSOLE in
+Config are wrong, the serial port is at 3F8, not 378.
+
++ A couple of updates to wol.c and wake.pl by Günter Knauff.
+
++ The Davicom 9009 and 9102 driver was contributed by Sten Wang of
+Davicom. It will be merged into tulip.c later.
+
++ Implement eepro100_disable. There have been reports of memory
+corruption after Etherboot has handed over to the booted image due to
+the live controller.
+
++ Matt Hortman reported a new Intel NIC, 82559ER, with different IDs.
+Added to file NIC.
+
++ Ranjan Parthasarathy reported another Tulip clone from ST Micro with
+different IDs. Added to file NIC.
+
+Released as Etherboot 4.6.11
+
++ Stefan Lesicnik sent in a report from Intel which explains what is
+probably wrong with the PnP header. BEV should point to the mainline
+vector, not to the part that installs the INT19H vector.
+
++ Hopefully finally fixed DHCP option limit problem. It was requesting
+large packets but not parsing them fully due to the length limit passed
+into decode_rfc1533(). Thanks to shredda for testing this.
+
++ Added the # modifier to printf, it prefixes 0x to %x and %X making
+printf formats shorter throughout. 0x%[xX] changed to %#[xX] in lots of
+files. Now if only I could make b,x,X the standard hhx,hx,x and get rid
+of I.
+
++ Andreas Neuhaus provided patches for multiple rx buffers for lance.c
+which made it work again with VMware.
+
++ Perl script to convert floppyfw floppies to netbootable images.
+
++ Marty Connor made some small changes to liloprefix and Makefile to
+make the LILO images SYSLINUX bootable also.
+
++ Make the default return value for _poll in skel.c 0 so that when
+driver writers implement _transmit first, it will not hang on garbage
+return values from _poll when it's called to flush the input queue
+before the first transmit.
+
++ EEPRO/10 driver now works. µs timer routines came in useful.
+
++ Anders Larsen sent in a patch to 3c90x.txt which makes it clearer.
+
++ Added more stuff to the documentation.
+
++ Fixed bug in mknbi that always did the equivalent of --ipaddrs=rom
+no matter what. Also removed undef from my variable list in TruncFD.pm
+so that it won't have problems with Perl interpreters.
+
+Released as Etherboot 4.6.12
+
++ Jim McQuillan sent in a patch for first-linux.S where it was assuming
+the argument in tag 129 (additional parameters) is a null terminated
+string, when it's a length counted string. A new routine, addkarg was
+created to handle this.
+
++ eepro100 should handle newer NICs with 256 byte EEPROMs now. This
+includes the onboard NICs on some motherboards, see file NIC. Thanks to
+Stephan Lauffer for helping with the fixes. WARNING: This code may have
+a bug that causes the onboard EEPROM to be corrupted. We believe we have
+found and removed the bug but please proceed with care.
+
++ DHCPDISCOVER was sending out one byte too many for PARAM_LIST.
+
++ In DHCPDISCOVER send "Etherboot" in VENDOR_CLASS_ID option (60). Will
+add code later to check for "Etherboot" in vendor encapsulated options.
+
++ Used µs timer routines in 3c509 for more accurate timing and hence
+better hardware detection. Use COMMAND_IN_PROGRESS bit to detect
+transmit complete instead of waiting for a fixed amount of time. Get rid
+of eth_vendor and associated tests, it doesn't serve any useful purpose
+since the driver was modularised long ago and the 3c509 detection status
+is stored outside of the driver now. Got rid of some unused global
+statics in 3c509.c, leftovers when the drivers were monolithic. Wait 2
+seconds after enabling TP interface to give it time to come up. This
+allows us to get rid of T509HACK in main.c.
+
++ Get rid of eth_vendor and associated tests in cs89x0.c, same reasons
+as for 3c509.c.
+
++ Moved the rest of the VENDOR_ and FLAG_ defines into ns8390.h, as
+ns8390.c is the only file that uses them now.
+
++ Use lower 32 bits of node address + current time for xid (network byte
+order). More likely to be distinct from other clients than just the
+current time, which is similar for all clients booted at about the same
+time.
+
++ Support for 16-bit code has been removed. XTs and ATs are pretty much
+dead now and in fact many Etherboot/16 drivers have been broken for a
+while but nobody noticed. This should make some of the code easier to
+maintain. If you really wanted 16 bit support, use an older version of
+Etherboot, maybe 4.4 or something like that, not sure when things
+started breaking for 16 bit mode.
+
++ Should not store IP and UDP headers at BOOTP_DATA_ADDRESS. Redefined
+bootp_t without IP and UDP headers. Now requested size of bootp packet
+matches storage available. Do not add sizeof(iphdr) + sizeof(udphdr) to
+bootp pointer in start32.S:xstart now. start16.S:xstart was broken
+because it did not do this addition but nobody noticed.
+
++ Removed array kernel_buf, saving 128 bytes and replaced with
+KERNEL_BUF, a pointer into the bp_file of the bootp_reply structure at
+BOOTP_DATA_ADDR. Note: this depends on the server not sending Option
+Overload which would use the sname and file fields for options, but we
+don't request this option so it shouldn't. Removed char *kernel,
+instead check KERNEL_BUF[0] just before booting and if null, use
+fallback filename. (This is needed for future extensions to booting
+protocol.)
+
++ Define a shorter tftpreq_t type for making requests instead of using a
+full sized tftp_t packet to reduce stack usage.
+
++ Defined macros for htonl/htons/ntohl/ntohs for cases where the operand
+is a constant, saving a function call.
+
++ Started on first32.c, a protected mode 32-bit version of
+first-linux.S, which should be far easier to read and maintain. Will
+boot basic Linux kernels correctly but doesn't handle ramdisk or
+kernel arguments yet.
+
++ Updated nfs-swap documentation in contrib/nfs-swap to point to
+Claus-Justus Heine's new web page.
+
+Released as Etherboot 4.7.13 (development)
+
++ Added more IDs for eepro100 variants taken from the Linux 2.2.18
+source. Should handle the EEPROM properly now, a few defines were wrong
+in 4.7.13. Loop counter timeouts in eepro100.c replaced with hardware
+timeouts. Don't loop waiting for packet in _poll, return 0 immediately.
+
++ first32.linux works. Does kernel arguments and ramdisk but doesn't do
+appended parameters from menu selections, which should be replaced by a
+more elegant menu scheme anyway. Needed gateA20 routines in
+mknbi-1.1/first32.c otherwise cannot access extended memory.
+first32.linux should be able to handle memory > 64 MB, which the old one
+couldn't. Support for first32pm call protocol added.
+
++ 3c595.c changed to use hardware timer for delays. Transmit routine
+waits for a fixed period after transmitting. Changed to check
+S_COMMAND_IN_PROGRESS bit. It also contains some of the same unused
+variables as 3c509.c and mentions 3c509 in some comments. Cleaned up.
+
++ Hmm, how come this wasn't fixed long ago? Should discard BOOTP/DHCP
+replies that are not to broadcast or own MAC address. I guess xid caught
+practically all of the non-matching packets. (Later: Actually the NIC
+should filter out packets we don't want, but leave test in anyway, it's
+the last test.)
+
++ Removed last vestiges of ETHERBOOT32 and ETHERBOOT16.
+
++ ETHER_ADDR_SIZE => ETH_ALEN, ETHER_HDR_SIZE => ETH_HLEN,
+ETHER_MIN_PACKET => ETH_ZLEN, ETHER_MAX_PACKET => ETH_FRAME_LEN. More
+Linuxy and therefore more familiar to programmers.
+
++ Cleared up confusion with 60/64 and 1514/1518 for minimum and maximum
+frame sizes. Practically always the right numbers are 60/1514, except
+that some chips count the FCS in the receive length, then we have to use
+64/1518.
+
++ Make __swap32 and __swap16 inline routines available globally as
+swap32 and swap16. eepro.c can use swap16 instead of making up one.
+
++ Make aui field in nic.h an int since it will be padded to a longword
+boundary anyway and call it flags so that other drivers can use it for
+their own purposes. Currently only 3c503 uses it to indicate AUI xcvr.
+
++ Make sprintf return number of characters written instead of a pointer
+to the last char written to be more consistent with standard C.
+
+Released as Etherboot 4.7.14 (development)
+
++ Thanks to Mark VandeWettering for the start of HomePNA (networking
+over phone lines) support for the AMD 79C978.
+
++ Bug fixed in first32.c handling of (ip|nfsroot)=X where X is not rom.
+
++ first32pm.linux works. No need to go into real mode to call first32pm
+and then it goes back to protected mode. Paves the way for extension
+routines to Etherboot. Implement program returns to loader flag in
+header field. Added option to mknbi to specify this.
+
++ first32*.linux: Check tag 128 present and correct before appending tag
+129. Also tag 129 should be appended to parameters before substitutions.
+
++ Merged cleanup_net into cleanup since they are always called together.
+
++ Floppy booting doesn't need to be passed BOOTP_DATA_ADDR.
+
++ Clean up variables associated with tagged image loading in osloader.c.
+
+Released as Etherboot 4.7.15 (development)
+
++ Duplicated 3c900 PCI IDs under 3c595 as some NICs apparently detect
+and work with the 3c595 driver but not the 3c90x driver, according to a
+report from Dirk Pfau. (The 3c90x series has two modes of operation,
+programmed I/O mode descended from the 3c509, good only for 10 Mb
+operation, and bus mastering mode, essential for 100 Mb operation. For
+network booting, either mode is acceptable.)
+
++ Removed auto from kernel parameters; it's the default already.
+
++ Use hardware timer instead of loop counter for transmit timeout in
+3c90x.c.
+
++ Define a jmpbuf type for setjmp and longjmp. Trim size to 7 longs,
+that's all that's needed. Standardise the return values from longjmp:
+-2: loader error, -1: timeout or ESC, 0...: various meanings to
+Etherboot main loader.
+
++ Ansify function headers in bootmenu.c.
+
++ Make _int10 return ax | (bx << 16) as result so that these can be
+accessed more efficiently in the following statements.
+
++ Make handleansi take unsigned int instead of unsigned char as
+argument, otherwise extra code will be generated to handle this
+according to ANSI rules. (Quite significant saving of 55 bytes.) Rename
+it ansi_putc for clarity.
+
++ Prefix getc, putc and ischar with console_ to make things clearer and
+to avoid confusion with the Unix getc, putc.
+
++ Add menu as a target to mknbi. Started source code for menu extension.
+Successfully transferred control to menu at 0x10000 and back. ANSI
+colour controls work, at least. Return end needs more work.
+
++ Started on ELF support in mknbi.
+
+Released as Etherboot 4.7.16 (development)
+
++ Added atftp 0.2 (ftp://ftp.mamalinux.com/pub/atftp/) to contrib/.
+Supposedly contains a tftpd that runs multithreaded, which may help
+people having problems with *inetd shutting down tftpds that spawn too
+fast.
+
++ Added a few more Tulip entries to config.c and NIC, not all of them
+have been confirmed working.
+
++ Got ELF format creation in mkelf-linux working now. At least one empty
+section header is required to make a valid ELF file.
+
++ Added code to support non-MULTIBOOT ELF when IMAGE_ELF is selected but
+IMAGE_MULTIBOOT is not. Booting from images created by mkelf-linux
+now works!
+
++ TAGGED_IMAGE is now not always selected. It's just the fallback if
+none of TAGGED_IMAGE, AOUT_IMAGE or ELF_IMAGE is selected. Therefore you
+must explicitly select TAGGED_IMAGE if you want it, and you have
+selected AOUT_IMAGE or ELF_IMAGE. Startup banner line displays all
+image formats accepted.
+
++ exit() in mknbi/start32.S should copy argument to %eax first.
+
++ Images with 0xAA55 in bytes 510-511 are no longer accepted, which
+should reject invalid formats now, e.g. Linux kernel images, which have
+a boot sector in the first block. Strictly this does not conform to the
+original netboot spec by Jamie Honan, which specifies that non-tagged,
+linear images starting from 0x10000 are allowed, but that format is
+pretty useless now. Any decent loading scheme needs a roadmap to the
+blocks in the downloaded file, which is what tagged, a.out, or ELF
+images provide in the header. Q: What is config_buffer in main.c for?
+Nothing else seems to use it. Is it a relic of non-tagged images?
+
++ Clean up lots of obsolete prototypes in etherboot.h. Ansify lots of
+function headers in main.c. Make lots of functions and variables in
+main.c static. Make bootmenu.c:getoptvalue() static.
+
++ Simple external menu program works!
+
++ More documentation cleanup, notably editing the compile options to
+match what has been done.
+
+Released as Etherboot 4.7.17 (development)
+
++ Marty Connor did it again! He found a long standing bug in the PnP ROM
+header which caused it not to be recognised by BIOSes. Now Etherboot ROM
+images are PnP compliant. I hacked makerom.c to fill in the offset of
+the ident string for the device string so that the BIOS can even print
+out "Etherboot" and the device ident on boot up.
+
++ Made demo menu program a bit more elaborate with timeout.
+
++ Igor V. Kovalenko fixed the Winbond W89C840 driver to use the hardware
+timer instead of CPU counter loops. Now none of the Etherboot drivers
+rely on CPU speed dependent loops.
+
++ Small fix to contrib/p910nd.c to not use getprotobyname which requires
+libnss_files.so, which may not be installed in all environments.
+
++ Small change to contrib/mkffwnb to allow the user to choose ELF format
+(by editing one line) instead of tagged format.
+
++ Patch to atftp-0.2 to make it accept a filename if the directory is a
+prefix of the filename. This is needed so that valid absolute pathnames
+will work. Patch sent to atftp authors.
+
++ Added support for filtering out replies which do not include a Vendor
+Class Identifier of "Etherboot" in the Vendor Encapsulated Options. This
+can be used to select only the DHCP servers which we want to get
+addresses from and reject the rest. Select the compile option
+-DREQUIRE_VCI_ETHERBOOT. This requires ISC DHCPD 2 or 3 AFAIK. (It's
+not documented in DHCPD 2, but it works.) Other DHCP servers may support
+VEO. (It's a RFC2132 option.)
+
++ Jim Thomas suggested a way, other than creating /fastboot, of
+preventing fsck from running on NFS root, ln -s /bin/true
+/sbin/fsck.nfs. Not verified but should work. Added to documentation.
+
+Released as Etherboot 4.7.18 (development)
+
++ Pavel Tkatchouk verifies that lance.c can handle PCnet-FAST III
+79c973. Added a new entry to lance.c and NIC. NIC entry not verified
+yet.
+
++ Enhanced disnbi to decode ELF images too.
+
++ Arrgh! There are old BIOSes that rely on the wrong order of the bytes
+in the device identifier in the PCIR and PnP structures. Wrote a Perl
+program swapdevids.pl to swap these bytes. Apply this to image file just
+before programming the EPROM.
+
++ Marty Connor suggested that the specs state that for PnP ROMs the
+unsuccessful return from boot should be int 0x18 rather than int 0x19.
+Using int 0x19, selecting L for local device doesn't work. Fixes needed
+in both loader.S and start32.S (get lret to work properly, instead of
+doing an int 0x19 directly, involved saving ss and sp in real mode
+instead of in protected mode).
+
++ Wrote a Perl program disrom.pl to display key structures of a ROM
+image.
+
++ Added call to binmode() in various Perl utilities so they should work
+under other OSes.
+
++ Added check in makerom.c to warn if 55 AA not found at start of image.
+It seems some people don't read the warning not to use the Linux
+supplied as86.
+
++ It seems Z is a recent addition to pack/unpack formats in Perl and
+even a Perl as recent as 5.004 doesn't implement it. Change Z5 in
+mknbi.pl and TruncFD.pm to a5 since we only need to compare it against
+'FAT12' and 'FAT16'.
+
++ Some errors found in osloader.c in the #ifdef IMAGE_MULTIBOOT
+sections. kernel should be KERNEL_BUF and union info should have
+unsigned short s[256];. Also kernel -> KERNEL_BUF for IMAGE_FREEBSD,
+obviously few FREEBSD users have tried compiling it.
+
++ Explain in docs that .com and .(lz)lilo images can be generated and
+touch briefly on how to use them.
+
++ Donald Christensen contributed translations of floppyload.S and
+loader.S to gas syntax. Currently they are in contrib/gassyntax/. They
+potentially allow us to throw away as86 and/or nasm and use GNU tools
+throughout, but I have to do some work on them: 1. I have to check what
+versions of gas accept the syntax, the 16-bit mode in gas was a recent
+enhancement; 2. I have to put back the #ifdef PCI_PNP_HEADER into
+loader.S and also bring it up to date to the recent patches.
+floppyload.S should be usable as is.
+
+Released as Etherboot 4.7.19 (development)
+
++ Donald Christensen completed the translation of loader.S and all the
+other .S files in the src directory that previously required as86 or
+nasm. No more futzing around with precompiled versions. Yipee!
+
++ Luigi Rizzo contributed a slightly hacked FreeBSD loader that works on
+floppy or hard disk. See boot1a.s for details. Makefile rules edited.
+Targets renamed .dsk and .lzdsk to indicate they're not floppy specific
+now. Documentation updated. I note that the loader is smart enough to
+figure out exactly how many sectors have to be read.
+
++ Renamed comload.S to comprefix.S which describes it better.
+
++ mknbi tools split out into separate package for independent
+development.
+
++ Use A32 instead of Z32 in unpack format in disrom.pl in case we
+encounter old Perl versions (< 5.005).
+
++ Vendor Class Identifier string that's sent out is now of the form
+Etherboot-x.y (13 bytes long).
+
++ Reduced size of ee_data in davicom.c to 32 bytes because we only need
+to access the MAC address in bytes 20:25.
+
++ Changed type of formal arguments to pci.[ch] routines to unsigned int
+except for the last argument, because in ANSI C parameter passing is
+like assignment and extra dummy variables and code may need to be
+generated if the formal argument type is not the the same size as the
+actual argument that gets pushed on the stack. Not insignificant
+overhead, reduction from 1853 to 1727 bytes due to change. Changed devfn
+and bus members of struct pci_device to unsigned char to enforce limit
+on type. Surprisingly this reduced the size further to 1667 bytes.
+Probably the compilier could do more optimisations after the last
+change.
+
++ Some drivers hardwired 0 for bus number in calls to pcibios_*
+functions. Changed to pci->bus, which is set in scan_bus. Only
+people with NICs not on bus 0 would have noticed.
+
++ Found a couple more old-style pre-ANSI C function declarations. Turned
+on -ansi and -pedantic for kicks and fixed some non-ANSIness, e.g.
+// comment in #define, text after #endif, casting memcpy arguments to
+void *, using void * instead of char *. Some char declarations changed
+to unsigned char.
+
+Released as Etherboot 4.7.20 (development)
+
++ I changed my mind. I think the format in disrom.pl should be Z32,
+otherwise it displays binary characters after the valid part of the
+string. For people with Perl < 5.005, please upgrade.
+
++ Moved RELOC down to 0x94000. Turned on USE_INTERNAL_BUFFER by default.
+Unless BOOTP_DATA_AT_0x93C00 is defined, use internal bootp strucutre.
+This gets Etherboot out of the area just below 0x10000 and the area from
+0x93C00-0x93FFF. DHCP packets can now be as large as the Ethernet
+payload. Later on, first32.c and the parameter area could expand a bit.
+In lance.c had to reduce RX_RING_SIZE (by reducing LANCE_LOG_RX_BUFFERS)
+from 16 to 4 to fit the driver. I'd like to hear feedback from lance
+users. Is 24kB of receive buffers really needed given that Etherboot
+uses stop-wait protocols?
+
++ Doug Ambrisko sent in some patches for FreeBSD: a correction for one
+typo I missed and changes to make compilation under FreeBSD easier.
+
++ Michael Sinz contributed patches to allow the FreeBSD loading code to
+load debugging symbols also.
+
++ Marty Connor contributed a SiS900 driver. Also pointed out that if
+ASK_BOOT <= 0, the prompt and read shouldn't even happen. Conditional
+code reworked.
+
++ Split documentation into user manual and developer manual. Added
+material.
+
+Released as Etherboot 4.7.21 (development)
+
++ Preston Wilson pointed out that ds.internic.net should be replaced by
+www.ietf.org in documentation URLs. Also RFC1090 should be RFC1094
+(NFS).
+
++ Marty Connor pointed out some broken links due to the split in
+documentation. Also comments don't match code in lance.c for change just
+above. Also passed on a bug found by a user of rom-o-matic.net where
+tftp was not defined when ANSIESC was defined. My mistake, I made it a
+static function when it needs to be exported to ansiesc.c.
+
++ Christoph Plattner found that the Etherboot startup messes up the
+flags while testing for a 386+. This doesn't affect Etherboot but it can
+cause the loaded operating system to crash. Fix: pushf before and popf
+after the CPU model testing.
+
++ Jean-Jacques Michel contributed patches to the via-rhine.c driver to
+make it work for the VT6102 model as used on some DFE530-TX Rev.A3 NICs.
+
++ Luigi Rizzo sent in a fixed boot1a.s that actually works on HDs now.
+
++ Stefan Furtmayr sent in a list of URLs to TFTP servers for NT. Added
+to directory contrib/Diskless-From-NT.
+
++ Paul Whittaker contributed a HOWTO in HTML format on booting with NT
+as the server. Added to directory contrib/Diskless-From-NT.
+
++ CJ pointed out that the advertised message size is > 1500 bytes.
+Define MAX_BOOTP_EXTLEN so that the size of the structure matches the
+Ethernet payload size.
+
+Released as Etherboot 4.7.22 (development)
+
++ Reintroduce the old Via-Rhine PCI IDs into file NIC and give the
+corresponding ROM images -old suffixes, in case some people are using
+the old chips.
+
++ Peter Kögel contributed patches to the SiS900 driver to make it work
+for the SiS630e and SiS730s.
+
++ Charles Dobson pointed out that when booting from a PnP BIOS, the code
+should not hook or restore the INT19H entry point. Put hooking code
+inside #ifndef PCI_PNP_HEADER and changed entry point in PnP structure
+from start19h to blockmove.
+
++ I have one report that gas 2.91 doesn't assemble loader.S because it
+can't handle all the 16-bit code. Since the benefits of using gas for
+all assembly code are great, and gas 2.95 has been out there for a long
+time, I regretfully say to affected users: upgrade your tools. Otherwise
+there may be a workaround by specifying the opcodes literally. I leave
+it to interested parties to try. If you do this, put in an #ifdef
+GAS291, naturally.
+
++ Updated contrib/tftp-hpa to 0.16 from ftp.kernel.org.
+
+Released as Etherboot 4.7.23 (development)
+
++ Rename nepci entry in file NIC to rtl8029 to avoid giving the
+impression that nepci will work for all PCI NE2000 clones. Make the
+issue of PCI IDs in ROMs clearer in documentation, both in the
+configuration and troubleshooting sections.
+
++ Tania Oka and Hyun-Joon Cha at about the same time found that
+implementing the rtl_disable() routine in rtl8139.c stopped random
+crashes in Linux later. It is important to disable the NIC after network
+loading.
+
++ Implemented _disable() routine in w89c840, 3c90x and via-rhine drivers
+too. Don't know how to do it for epic100.
+
++ p910nd-0.4 in contrib/ has -f device option now to specify other
+printer ports, e.g. USB.
+
++ Robb Main found a bug with the #ifdef logic in loader.S. This may fix
+problems with BIOS detection.
+
+Released as Etherboot 4.7.24 (development)
+
++ Paolo Marini sent in some code to make it work on his bare metal (no
+standard BIOS or peripherals) platform. This may be a useful starting
+point for some applications. See contrib/baremetal/.
+
++ Eric W. Biederman contributed a Perl script in
+contrib/award_plugin_roms/ to list flash BIOS plugin components.
+
++ Marty Connor rewrote the Tulip driver to handle many more variants.
+
++ For PCI ROMs loader.S can now detect if it's being called from a PnP
+BIOS and choose to hook INT19H if not.
+
++ Pass struct *rom_info in priv_data to probe routine. This is to allow
+drivers to decide, based on the ROM address, which one of multiple
+instances of identical network adaptors to activate. Started on 3c509
+code to use this but need to understand 3c509 contention resolution
+mechanism first.
+
++ Link src/lzhuf.c to contrib/compressor/lzhuf.c so that we don't need
+to refer to contrib/compressor/lzhuf.c anymore in Makefile.
+
+Released as Etherboot 4.7.25 (development)
+
++ Minor documentation edits, merged in NIC entries for newly supported
+Tulip variants from Marty Connor.
+
++ One last minute change, Robb Main suggested calling cs89x0_reset()
+from cs89x0_disable() to shutdown the hardware cleanly.
+
++ Updated tftp-hpa to 0.17.
+
++ Slight mod to lzhuf.c to make compression statistics report shorter.
+
+Released as Etherboot 5.0.0 (production)
+
++ Donald Christensen found a small bug in osloader.c. Not all context
+was cleared on tftp restart which caused restarted tftp loads to fail.
+
++ Correct a small error in setting %sp when not running at 0x9xxxx.
+Now relocation to 0x84000 works.
+
++ Marty Connor added a generic Tulip entry and renamed the Macronix
+entries because PHP doesn't like strings starting with digits (for
+rom-o-matic.net).
+
++ In loader.S, move code to save ROM segment and length to before jump
+to new segment, otherwise if MOVEROM is defined, then the ROM segment is
+always 0x8000. In etherboot.h, define an inline function to say if a ROM
+address is ok to boot from. Allow if < 0xC0000 or matches assigned ROM
+address of NIC.
+
++ Thomas Kessler found a bug in vendortags.sgml re option-NNN tags in
+dhcpd.conf, the wrong syntax was presented. However on trying the
+option-NNN syntax documented in the dhcp-options man page, it was
+discovered that option option-NNN is no longer supported in the old way
+in recent versions of ISC dhcpd v3; a new syntax should be used. Added
+note to vendortags.sgml to warn users.
+
++ Incorporated changes suggested by Hannu Martikka to #define
+DEFAULT_KERNELPATH in etherboot.h for rarp(), and display the TFTP
+server address before filename in Loading: message.
+
++ Split off documentation into separate package in anticipation of
+production/development series split. Moved previous LOG to top level.
+Moved distribution section of index.html into separate web page so that
+index.html will be less ephemeral.
+
+Released as Etherboot 5.0.1 (production)
+
++ Arkadiusz Miskiewicz pointed out that --oformat should be used instead
+of -oformat as old ld accepts both while new ld requires --oformat.
+
++ contrib/{tftp-hpa,atftp} are distributed separately from the
+distribution page to make them easy to update.
+
++ Eric Biederman contributed many small changes in the code to improve
+the behaviour in exceptions and generally improve the code structure:
+
+1) Cleanup etherboot restarting. There is now only one place that needs
+to test for EMERGENCYBOOTDISK.
+
+2) Change pci.c as I have suggested. It is setup to scan every possible
+pci bus until it finds an etherboot card.
+
+3) Change osloader.c so that if an image that can return, but isn't
+supposed to it restarts etherboot with -2 instead of the returned value.
+
+4) Rewrites the delay logic so that we compute how long we should sleep,
+and then sleep the whole time in await_reply so in a congested networks
+we don't miss slow packets.
+
+5) divides load into load & load_configuration. This removes the need
+for the weird bootp_completed variable. And makes it a little more
+explicit what we are doing.
+
+6) add an interruptible_sleep function so that we can sleep and still
+process keystrokes.
+
+7) rewrites the restart logic:
+ - renames jmp_bootmenu to restart_etherboot.
+ - removes bootmenu (The function isn't)
+ - It explicitly does an eth_reset & eth_probe pair to reinitialize
+ the interface. This should help if someone has plugged the
+interface into a different switch since booting started.
+ - moves ASK_BOOT and TRY_FLOPPY_FIRST into their own functions.
+ - On every restart calls ask_boot and try_floppy_first. Allowing you
+ to change your mind on how you want to boot after network booting
+starts.
+
+8) In cleanup calls both eth_disable (to disable the interface) &
+eth_reset to make certain the interface can be initialized from linux.
+(If nothing else this should cause more hidden bugs to show up).
+
+9) Restart etherboot when downloading a bootfile fails, instead of just
+looping trying to get that file. Allowing typos in dhcpd.conf to be
+corrected without having to reboot the client machine running etherboot.
+
+Released as Etherboot 5.1.0 (development)
+
++ All the changes from 5.1.0 carried over except calling eth_reset()
+from cleanup().
+
++ Marty Connor, funded by Sicom System (http://www.sicompos.com/), wrote
+a driver for NICs based on the National Semiconductor DP83815, e.g.
+Netgear FA311/FA312. Also independently created by Jason McMullan just
+at the time Marty released his driver. Thanks for the effort Jason;
+great minds think alike. Both are based on Donald Becker's Linux driver,
+of course.
+
++ Doug Ambrisko contributed a patch to take environment bindings for
+FreeBSD kernels from a BOOTP/DHCP option or config variable.
+
++ Dax Kelson contributed an example of an ISC DHCP config file that uses
+Vendor Class Identifier to tailor the response to Etherboot clients.
+Also discovered that the Etherboot VCI should also be sent in the
+DHCPREQUEST message, in addition to the DHCPDISCOVER message. Note that
+the DHCP server must be set to non authorititative if you have an
+authoritative server running already or it will interfere with that
+one's operation.
+
++ Peter Lister and Vasil Vasilev contributed changes to generate .pxe
+images bootable via PXE.
+
++ Eric Biederman added code to 3c90x.c to enable the NIC: set up
+busmastering and set the latency timer in case the NIC is not already
+set correctly, and fixed a couple of related bugs in eepro100.c.
+Verified that the 3c90x driver works for the 3c980.
+
++ Moved strncmp from osdep.h to linux-asm-string.h. Use the general
+version using string ops, not the deprecated 486 version (what was I
+thinking). Also added strlen, needed for FreeBSD patch above.
+
++ Thanks to gcc 3.0, found and corrected a couple of C constructs of
+undefined semantics in rtl8139.c and lance.c of the form: i = ++i &
+MASK;
+
++ In Config/CFLAGS32: changed -m386 to prefered form, -mcpu=i386,
+changed -O2 to -Os, and added -ffreestanding. These changes allow
+warning-free compilation under gcc 3.0. Only mimimal testing has been
+done with gcc 3.0 compiled binaries, we hope there are no problems but
+don't throw away your gcc 2.9.5 yet.
+
++ Added an .org 0 to loader.S just before _start. May or may not fix
+alleged assembly problem with gas 2.11.
+
++ Cosmetic change: in boot1a.s replaced "loaded" with "done\r\n" so that
+Etherboot messages start at beginning of line.
+
++ More improvements to contrib/mkffwnb.
+
+Released as Etherboot 5.0.2 (production)
+
++ Added missing rules in genrules.pl for .pxe and .lzpxe images.
+
++ Peter Lister unified pxeloader.S into loader.S. pxeloader.S not
+required now. Also fixed .lzpxe.
+
++ Added missing int i; declaration in try_floppy_first().
+
++ Load %edx with dev just before calling xstart in floppy.c:bootdisk()
+so that %dl will have device number, just like entry from BIOS.
+
++ Merged in Eric Biederman's patches to build .ebi images that run under
+LinuxBIOS. To make an image, edit Config to enable the EBI options (and
+disable TAGGED_IMAGE), then make bin32/driver.ebi, where driver is the
+name of a supported PCI NIC.
+
+Released as Etherboot 5.1.1 (development)
+
++ The rotating bar progress display has been replaced by a sequence of
+dots, one for each transmitted packet. This is kinder to dumb displays,
+e.g. serial terminals, and gives a better feel for how the loading is
+going. If you want the rotating bar, use -DBAR_PROGRESS.
+
++ In loader.S change .fill 0x18-(.-_start) to .org 0x18. Might help
+people having errors assembling it.
+
++ Do Jong Gwan found a 3Com 980 with PCI ID 0x9805. Added to config.c
+and NIC. Added for good measure 0x7646 which is listed as 3CSOHO100-TX
+in Linux kernel 3c59x.c.
+
++ Add a rule to the Makefile to check for gcc 2.96, which is buggy, and
+tell the user to use kgcc instead if found.
+
++ Till Straumann added long-needed code to warn when fragmented packets
+seen (encountered on a wireless link) and to do UDP packet checksumming.
+
++ A trio of patches from Klaus Espenlaub, to fix a lance ring pointer
+error in lance.c, to fix a format error in the multiboot call in
+osloader.c and a patch to enable powersaving while waiting (good for
+compute clusters and VMware), this one requiring the new option
+-DPOWERSAVE in compiles.

++ While we are adding compile options, -DFLOPPY has been renamed to
+-DCAN_BOOT_DISK as FLOPPY has been a misnomer ever since the ability to
+boot /dev/hdX and /dev/sdX was added.
+
++ Spurred by correspondence from Till Straumann and Klaus Espenlaub,
+hacked printf to not require a buffer. Now printf output can be
+arbitrarily long as it no longer needs a buffer to assemble the
+characters before sending to putchar; it outputs on the spot for
+non-format chars and %s items, and at the end of the item for non-%s
+items.
+
++ DRIVER AND EXTENSION WRITERS NOTE! (s)printf formats have been changed
+to be a subset of those in glibc to reduce confusion. The changes are %x
+-> %hX, %b -> %hhX, and %I -> %@. Lower case x formats are also
+available now. The only variances from glibc are %@ for dotted quad IP
+addresses (formerly %I; %I is now used), %! for 6 byte Ethernet
+addresses, and that printf returns void. Thanks to Klaus Espenlaub for
+assistance on this, after adding the %! format, he cleaned up all of the
+Ethernet address display code in the drivers.
+
++ More cleanup patches from Klaus Espenlaub (he's better than lint;
+people who have used Bell Labs Unix will know what lint is). Changes
+noted here for posterity.
+
+3c509.c: consistent non-use of # modifier for debugging output
+3c595.c: consistent non-use of # modifier for debugging output
+3c90x.c: use optimal %x variant, PCI bus/function numbers are always small
+Config: Replace a TAB by two spaces inside the descriptions
+eepro100.c: 6->ETH_ALEN, PCI bus/function numbers are always small
+floppy.c: optimal %x variant
+genrules.pl: consistent use of TAB characters
+i82586.c: the ENET address printing patch for the EXOS205 got lost somehow....
+main.c: cleanup of the UDP_CHECKSUM comment some editor messed up, make the
+ assembly fragment use the normal formatting, fix the register assignment
+ specification for the %bx register to use the "b" constraint instead of
+ "bx" - the x makes no sense...
+natsemi.c: %X case fix...
+ns8390.c: optimal %x variant
+pci.c: fix bad Linux port (most messages truncated the hex values)
+sis900.c: a value read with inl() should probably(!) be printed with %X
+start32.S: move around the #endifs a little
+timer.c: fix space/tab characters
+via-rhine.c: all values "printed" inside the comments are 32 bit integers
+wd89c840.c: PCI bus/function numbers are always small
+
+Released as Etherboot 5.0.3 (production)
+
++ New version of contrib/Diskless-From-NT/furtmayer.html. I mangled the
+previous version by forgetting to extract with metamail so it was still
+quotable-printable encoded.
+
++ Renamed do_printf to vsprintf because that's the standard function it
+has the same signature as.
+
++ More patches from Klaus Espenlaub. In his own words:
+
+The patch to add UDP checksums for transmitted packets is attached.
+Just don't be surprised if some packet sniffer tells you that the
+checksum for the NFS_LOOKUP packets are wrong and that the filename is
+truncated. It's a bug in the sniffer, not in Etherboot.
+
+Oh, and the small change in udpchksum() almost makes up for the
+increased code size.
+
+I also rewrote the NFS code to use pointers instead of array accesses.
+This reduced the code size by 124 bytes. Patch attached.
+
+The last patch in this mail fixes misc things: a typo in misc.c
+(DOT_PROGRESS instead of BAR_PROGRESS), and twiddle() is only called if
+the packet type is IP. This makes the output nicer - the dots are also
+printed in some non-approriate places for ARP reply packets. The
+important packets are IP anyway.
+
++ The option BOOTP_DATA_AT_0x93C00 is deprecated, in preparation for
+expanding the parameter area and the first32.c area.
+
++ Marty Connor found a typo in index.html, should be: Etherboot can work
+with..., not Ethernet can work with... Ooops.
+
++ Eric Biederman tried a patch of Preston Wilson's and discovered that
+DI should be prefixed by ES in the test for a PnP BIOS in loader.S to be
+sure. Furthermore some BIOSes are not fully compliant and we need an
+#ifndef PNP_BUT_NOT_BBS_COMPLIANT to work around that.
+
++ Oops, there's no entry in config.c for the DFE530TX+ even though
+there's one in NIC.
+
+Released as Etherboot 5.0.4 (production)
+
++ Fixed a struct alignment (8-byte constraint) problem in lance.c caused
+by the introduction of the rx_idx field by moving rx_idx to the end of
+the struct. Found by Rizsanyi Zsolt. Klaus Espenlaub also suggested
+increasing all the Rx buffers by 4 bytes because of the checksum stored
+at the end.
+
++ Fred Gray contributed changes in tulip.c to check for a duplex
+connection and to modify the controller register if so. Marty fixed an
+unassigned to "negotiated" variable.
+
++ Mark G of Inprimis Technologies contributed another FA311 (National
+Semiconductor DP83815) driver, also based on the Donald Becker Linux
+driver.
+
++ Armin Schindler contributed a patch to allow booting LynxOS KDI
+images.
+
++ Moved code to set PCI busmastering and reasonable latency to a routine
+in pci.c and added calls to this routine from all PCI drivers.
+
++ New files for contrib/mkffwnb for version 1.9.11 and 1.9.16.
+
++ Removed BOOTP_DATA_AT_0x93Cxx option.
+
++ Convert epic100 driver to use hardware timer for transmit timeout and
+remove polling loop from receive routine.
+
++ Steve Tilden pointed out that BOOT_INT18H is a LCONFIG option, not a
+CFLAGS32 option. Put note under option documentation and also added a
+commented-out example in Config. Steve also contributed a patch¸ in
+contrib/auto-default, which autoboots from the next device if a disk is
+detected.
+
++ PNP_BUT_NOT_BBS_COMPLIANT option renamed to BBS_BUT_NOT_PNP_COMPLIANT.
+
++ Merged in Vasil Vasilev's changes to loader.S to release memory taken
+by PXE properly.
+
++ E820 memory detection routines added by Eric Biederman. May increase
+size of bss segment and push large drivers, e.g. Tulip, nearer to limit,
+please report.
+
++ Default to -DCONGESTED in Config, may help on busy networks.
+
++ Add Holtek HT80232 to list of NE2000 PCI clones.
+
++ Remove prohibition on loading < 0x10000 in ELF images since by default
+drivers don't use memory < 0x10000 any more, with 48kB to run in.
+
++ Put define of ETH_MAX_MTU in etherboot.h inside #ifndef so that it can
+be overriden from Makefile.
+
++ Gustavo Junior Alves added .cvsignore files for src/bin and src/bin32.
+
++ Short note on how to make tomsrtbt netbootable in contrib/tomsrtbt.
+
+This release is dedicated to the memory of my mother (July 1917 -
+November 2001) [Ken Yap].
+
+Released as Etherboot 5.0.5 (production)
+
++ Changes to enable fa311too driver which were overlooked in 5.0.5.
+
++ Chien-Yu Chen sent in patches to support the SiS630ET. Independently,
+Doug Ambrisko made the same changes. Marty Connor tidied the patches.
+
++ In misc.c, when enabling/disabling Gate A20, call int 0x15 with
+ax=0x240x to do handling first, and if that is not supported, fall back
+to using the keyboard controller. Hopefully this will solve Gate A20
+problems for recent BIOSes.
+
++ Add missing entry to config.c for the Macronix 98713 (device ID
+0x512). But latest report is that it doesn't transmit. Anybody wanna
+debug?
+
++ Omit test for pointer to $PnP string for ISA NIC images, it may
+trigger false recognition of a PnP ROM. Just use legacy mode.
+
++ Merged in Christopher Li's Intel E1000 gigabit Ethernet driver.
+
++ RISKO Gergely found that the ADMTek Comet 983 works with the tulip
+driver if you provide the right PCI IDs.
+
++ Rohit Jalan contributed patches to support FreeBSD booting via PXE.
+(genrules.pl needed hacking to make it ignore the system includes in
+osdep.h.) Anybody want to see if it can be made to support pxelinux?
+[Glanced at it and I think general PXE support may be hard, you may need
+an Etherboot specific secondary loader. - Ken]
+
++ Merged in Eric Biederman's patches to allow trying all PCI devices.
+
++ From Eric Biederman: A small patch to allow the serial port parameters
+to be unchanged at activation. Major changes to start32.S to merge
+LinuxBIOS support. New files for LinuxBIOS support. PCBIOS specific
+functions split out into pcbios.S. Massive clean up of PCI subsystem
+logic.
+
++ Jean-Jacques Michel sent in a fix for via-rhine.c to make sure the
+transmit is finished before returning from the _transmit routine.
+Also found a bug in gcc 3.0.3 that affected rtl8139.c. Moving the
+assignment to nstype in _transmit two lines up avoids it.
+
++ Based on the experience of Yedidyah Bar-David, in eepro100.c,
+increased udelay around line 533 after getting MAC address to
+udelay(10000).
+
++ Added PCI IDs for RTL8129, which can use the rtl8139 driver.
+
++ Added PCI IDs for 3Com905 with device ID 0x9058. Confirmed working by
+Fabio Papa.
+
++ Added PCI IDs for D-Link 528, which is a PCI NE2000 clone.
+
++ Philip R. Auld found a block number rollover bug due to promotion to
+signed in main.c.
+
++ Luigi Rizzo sent in a patch to nfs.c to implement an adaptive timeout.
+
++ New config files for floppyfw-1.9.19 in contrib/mkffwnb/.
+
++ Glenn McKechnie contributed a Perl script for making a netbootable
+image from the Dachstein LRP firewall distribution floppy. It's in
+contrib/mklrpnb/
+
++ At the request of Greg Beeley, who got irate mail from kernel NIC
+developers, put in a warning in the Makefile about the 3c90x XCVR
+options which may affect later operation with the Linux driver. For you
+tinkerers out there, if you don't know what you're doing, please read
+3c90x.txt over and over again until you understand what those options
+do. If you don't understand, please ask on the Etherboot mailing list.
+And don't complain to the kernel developers, it's nothing to do with
+them. If you must change the XCVR options on a board, please document it
+prominently on the board so that those who come after you won't
+encounter strange behaviour and complain to the kernel developers.
+Greg also supplied a patch to 3c90x.c to print a warning message.
+
+Released as Etherboot 5.0.6 (production)
+
++ Andrew Bettison sent in a patch and the explanation: Here's a patch
+for some changes I made to Etherboot-5.0.6 because it didn't work with a
+SMC EtherEZ in an old PCI/ISA bybrid bus system. The ISA shared memory
+isn't accessible on many such systems, so the only way to do I/O to the
+card is in Programmed I/O mode. I studied the Linux 2.2.19 driver
+(drivers/net/smc-ultra.c) and hacked what I figured was equivalent code
+into src/ns8390.c, and it eventually worked. All my new code is enabled
+with -DWD-790_PIO.
+
++ Small error in the ADMTEK Comet 983 IDs fixed.
+
++ Michael Rendell sent in patches for 3c90x.c to get the MAC address
+from location 10 of the EEPROM onwards, like the Linux driver does. Some
+905s have the MAC address at both 0 and 10 which is why it worked for
+some boards.
+
++ Michael Brown sent in drivers for 3 wireless NICs based in the prism2
+chipset, and a small patch to rtl8139.c to abort detection on no link.
+
++ Rewrote makerom.c in Perl to give makerom.pl.
+
++ Rewrite genrules.pl to parse a new NIC format.
+
++ Timothy Legge contributed a 3c515 driver. Requires a ISA PnP BIOS.
+
++ Modified call to int15h/e801 in pcbios.S to check for return values in
+CX, DX in case BIOS doesn't return them in AX, BX.
+
++ Richard Chan sent in PCI IDs for another Intel EEPRO100 product.
+Omigawd will they ever run out of EEPRO100 model numbers. :-)
+
++ Changed location of setup header from 0x97e000 to 0x93e000 in
+mkQNXnbi.c for recent Etherboot versions.
+
++ Renamed membase to addr1 to reflect its lack of predefined meaning in
+PCI config space. Should do similar to ioaddr, but too much work.
+
++ Samuel Clememts found another Intel EEPRO100 device ID, 0x1039.
+
++ Updated instructions in contrib/tomsrtbt for latest 2.0.103 release.
+
++ Folded in changes by Michael Brown to send PCI and ISA IDs to the
+server and to encapsulate Etherboot specific options. Changed scheme to
+send fixed binary structure instead of variable length string.
+
++ Bug in sis900.c, wrongly classifies revisions 0x81 and 0x82 because
+first test catches too many revisions. Changed to match the Linux
+driver.
+
++ Fotis Andritsopoulos found a small bug in cs89x0.h, TX_AFTER_ALL
+should be 0x0C0.
+
++ Great idea by Eric Biederman. Ignore DHCP offers with zero server
+IP, or null filename unless DEFAULT_BOOTFILE is defined. This will
+ignore most Windows DHCP servers.
+
++ Patrik Weiskircher sent in a patch for rtl8139.c to bring it up to
+date with the Linux driver.
+
+Released as Etherboot 5.0.7 (production)

++ Should prepend start16.bin to .com images, they didn't work and nobody
+noticed.
+
++ PM stack was getting clobbered by zeroing of BSS, move to own segment
+in etherboot.lds. Move %ss out of the way of Etherboot in comprefix.S.
+Now Q works from .zrom and sort of from .com (DOS is odd after return).
+
++ Make ASK_PROMPT reflect the device options available.
+
++ Removed many outdated comments and updated others.
+
+Released as Etherboot 5.1.10 (5.2 release candidate 2)
+
++ Make floppyload.S and liloprefix.S call instead of jmp to the image so

+
++ Put http://etherboot.org in prompt and ID string.
+
+Released as Etherboot 5.2.0 (production)
+
++ Print F? if no filename in DHCP offer.
+
++ Make lance.c throw a compile error if -DRELOCATE is used.
+
++ pcnet32 driver ported by Timothy Legge.

+the image will no longer fit in memory. I don't want to choose a subset
+of drivers as everybody will have different preferences. So I'm going to
+piss off everybody equally by deleting the rule. Use the multiple driver
+rule (driver1--driver2--...) and select your own subset of drivers.
+
+Released as Etherboot 5.3.12 aka 5.4RC3 (development)
+
++ Changes to Makefile.main and Config to collect FILO objects in
+filolib.a. This allows FILO to be excluded from compilation and linking
+with one Makefile define.
+
++ Reverse site DHCP option changes, should apply for official
+assignment.
+
++ RIS filename patch which seems to work for many people.
+
++ Thanks to the help of Daniel Nilsson, tracked down and fixed a bug
+where the tftp code did not fall back to 512 byte blocks when an OACK
+was NOT received.
+
++ Removed dead code related to CAN_BOOT_DISK.
+
++ Clarified that BOOT_DISK and BOOT_FLOPPY options only work with
+LinuxBIOS and are not replacements for PCBIOS functions.
+
++ Renamed EMERGENCYDISKBOOT to EXIT_IF_NO_OFFER.
+
++ Builtin menuing DHCP options are gone.
+
++ Paolo Salvan submitted changes to arch/i386/Makefile to make .com
+images compressed.
+
++ Eric Biedermann made .*elf images work again and cleaned up the build
+procedure in the process. The hardwired virtual RELOCADDR is no more,
+the virtual base is 0. He also added code to display which protocols are
+compiled into the image.
+
+Released as Etherboot 5.3.13 aka 5.4RC4 (development)
+
++ Lots of fixes by Eric Biederman. Symbols for protected mode segment
+and prefix segments separated. Multiple ASM statements combined to
+ensure compiler keeps them intact. Allocate real mode stack if none in
+use. Protect low memory interrupt vectors. Makefile rules for various
+prefixes factored. Dynamic relocatable image support.
+
++ Fixes by Michael Brown. Cleanup of PXE and UNDI code.
+
++ Patch to Tulip driver for missing PCI ID.
+
++ Fixes to genrules.pl by Kenneth Sumrall.
+
+Released as Etherboot 5.3.14 aka 5.4RC5 (development)
+
++ Small ARMNOMMU architecture fixes by Toby Lorenz.
+
++ Patch to Tulip driver for additional PCI ID by Ramesh Chander.
+
++ Proxy DHCP support, catrom.pl script, flat real mode support, and
+e1000 fixes by Michael Brown.
+
++ New PHY support for tg3.c by Timothy Legge.
+
++ FS Protocol support by Radim Kolar.
+
++ FILO config changes by YHLu.
+
++ Support for compilation on AMD64 for i386. makerom.pl fixed not to
+change product string pointer if one already exists.
+
+Released as Etherboot 5.3.15 aka 5.4RC6 (development)
+
++ Minor additions and amendments to acknowledgements.
+
++ Added Doug Ambrisko's FreeBSD patch to freebsd_loader.c. Doesn't
+hurt FreeBSD 4 and seems to help FreeBSD 5 get further in booting.
+Should not affect other image types since it modifies only one file.
+The part of the patch relating to osloader.c was already present.
+
+Released as Etherboot 5.4.0 (production)
+
++ Added PCI ID for Fujistu Siemens Futro C200 by Martin Vogt
+
++ Liu Tao contributed a driver for the AMD8111 based on the Linux
+driver
+
++ Till Straumann patch for Sporadic eepro(10) RX problems after reboot
+
++ Hermann Gausterer sent a patch to support additional Broadcom PHYs
+

+Etherboot 5.4.0
+
+PXE is now supported. You will also need to configure your server to
+provide a pxelinux.0 loader file, kernel and initrd images, and a
+pxelinux.cfg directory with a appropriate configuration spec files.
+
+See the PXELINUX home page at:
+
+ http://syslinux.zytor.com/pxe.php
+
+for more information.
+
+There is no longer a default target for make. You must specify an
+argument to make. Help text is now provided to indicate possible make
+targets.
+
+It should be possible to compile Etherboot with gcc >= 3.3.3, including
+gcc 3.4.x now that a couple of bugs have been tracked down. Please mail
+reports of success or failure to the etherboot-users list, together with
+the versions of gcc and binutils used.
+
+gcc 2.x is not supported anymore. You need at least gcc 3.x to compile
+etherboot due to C99 constructs.
+
+Removed etherboot(-pci)?.* rule because there are too many drivers and
+the image will no longer fit in memory. I don't want to choose a subset
+of drivers as everybody will have different preferences. So I'm going to
+piss off everybody equally by deleting the rule. Use the multiple driver
+rule (driver1--driver2--...) and select your own subset of drivers.
+
+In order to create .iso and .liso images you will need to have the
+packages mtools-3.9.9 or later, and syslinux-2.08 or later installed on
+your system. These packages are available in various locations and
+formats. .liso images are like .iso but use floppy emulation. If you
+have a very old BIOS and .liso images don't work you may wish to try
+adding the -s option of syslinux as a last resort.
+
+EMERGENCYDISKBOOT has been renamed EXIT_IF_NO_OFFER, which describes it
+better.
+
+Menuing using DHCP options (mknbi/menu.c) has been removed.
+
+.exe format can be generated by doesn't work so not publicised.

+This utility was apparently writen by John Finlay and came to me
+via Richard Schroeder who got it from Greg Beeley. John, if you want
+to be credited with your full address or whatever in the Etherboot
+documentation, please contact me (Etherboot maintainer).
+
+1/18/2000 Marty Connor (mdc@thinguin.org) added code for the 3C905C
+with AT49BV512 Flash memory, and created cromutil and bromutil to
+differentiate the versions. cromutil is for 3C905C and bromutil is
+for 3C905B.
+
+Be careful. You can easily erase your Flash memory using these
+utilities. Make *sure* to back them up first using the "read"
+command. You must "erase" before using "prog" to program the chip with
+Etherboot code. This code comes with NO WARRANTY, and you take sole
+responsibility and liability for whatever it does. Read the
+"romutil.txt" file for more information on commands.
+
+That being said, if you are programming a 3C905C-TXM (for example)
+you would do something like this:
+
+ $ cd etherboot-x.x.x/contrib
+ $ tar -zxvf n3c905xutil.tar.gz
+ $ cd n3c905xutil
+ $ make
+ # replace 0x6600 with whatever the IO Addr for your card is!!!!
+ $ ./cromutil 0x6600 read > 905cbackup.bin
+ $ ./cromutil 0x6600 erase
+ $ ./cromutil 0x6600 prog < 3c90x.lzrom
+
+You should now have an Etherboot-enabled 3c905C-TXM.

+I wrote the attached little util program to try out the basic approach
+and thought that you might find it useful as well as providing some
+simple testing. It isn't a final solution so the interface is rough. The
+program must be run as root on an Intel based machine.
+
+The key point is that the IO address needs to be entered - I grab it
+from the dmesg output:
+
+eth0: 3Com 3c905B Cyclone 100baseTx at 0xe400, 00:10:4b:d2:5e:0d, IRQ
+11
+
+or "cat /proc/pci" to find the "I/O at XXXXXX" for your 3Com Card.
+
+Some example commands are:
+
+romutil 0xe400 erase - erases the ROM contents
+romutil 0xe400 protect - enables the Software Data Protection
+on the ROM [3c905B only]
+romutil 0xe400 unprotect - disables the Software Data Protection
+on the ROM [3c905B only]
+romutil 0xe400 id - displays the manufacturer and
+device IDs
+romutil 0xe400 read >file - writes the contents of the ROM to stdout
+romutil 0xe400 prog <file - writes the contents of the stdin into the
+ROM (<64k)
+
+I tried reading and writing the ROM while doing large ftp transfers and
+experienced no problems. I didn't spend much time worrying about the
+possible race conditions. My system has lots of resources (450MHx P2,
+128MB RAM) so it might not provide the best test candidate.
+
+Let me know what results you get if you try it out.
+
+Thanks
+
+John

+1. Introduction.
+
+
+1.1. What is it for?
+
+This document describes how to build software distribution to run Java client on diskless
+terminal booted from Microsoft Windows 95/98/NT workstation. Package can also be easily
+modified to be used as Linux terminal or X Windows terminal's software. I found it also
+convenient for setup over the Ethernet of floppyless PS's, hard disk of which for some
+reason can not be accessed (sealed case under warranty, etc.).
+
+
+1.2. Do we need this HOWTO?
+
+To be honest, I'm not sure. There are few excellent HOWTO's (see 3. Recources) that up until
+recently I considered quite sufficient to build what I've done two years ago. But since my
+project uses MS Windows as a file server vs. traditional NFS there were some know-how's
+involved which number of people wanted to see in some formal document.
+
+
+1.3. A bit of history.
+
+My project at that time (1996) was to find OS/JVM that will allow to run Java application
+on hardware we manufacture. Hardware is practically generic x86 PC except it has no keyboard,
+hard drive, floppy drive, mouse, but touchscreen over LCD, plus some POS specific peripherals
+(badge reader, credit card reader, etc.). Due to cost consideration it had no any significant
+storage, so OS and Java client along with support binaries, libraries etc. had to be loaded
+remotely. Because our clients are exclusively Windows shops, Server had to be Windows as well.
+During evaluation of different commercial OS'es along with JVM's available it become apparent
+to my surprise that most promising solution was GPL one - Linux.
+
+
+2. Project description.
+
+2.1. Packaging.
+
+The whole distribution consists of remote file system (RemoteFS) residing on MS Windows
+server (NT Workstation, NT Server or Windows9x) and tagged bootable image.
+
+
+2.2. Image.
+
+Image (~1.5MB) is generated by mknbi utility that comes with Etherboot package
+<http://etherboot.sourceforge.net>. It can include minimal root file system (MRFS)
+like in my case (since I had to boot client from MS Windows server and Linux kernel doesn't
+support SMBFS-Root, only NFS-Root. So I had to keep rootfs in the ramdisk). To generate
+image the following script can be used.
+
+#!/bin/sh
+# mkrootnet: makes tagged netbootable image
+# This image includes kernel and minimal root filesystem
+# to do initial boot.

+echo "Unmounting $MOUNT"
+umount $MOUNT
+cd $curdir
+echo "Copying $DEVICEFILENAME to $ROOTFS"

+echo "Compressing $ROOTFS, it may take a while"
+echo "Please wait..."
+if [ -f $ROOTFSGZ ];then
+ rm -f $ROOTFSGZ
+fi
+gzip -c $ROOTFS>$ROOTFSGZ
+rm -f $ROOTFS
+echo -e "\nCreating netbootable image"
+cp $KERNEL $KERNELTMP
+mknbi -d ram -i rom -r $ROOTFSGZ -k $KERNELTMP -a $CMDLINE -o $BOOTIMAGE
+echo "Uploading $BOOTIMAGE to $UPLOAD"
+cp $BOOTIMAGE $UPLOAD
+echo "Cleaning after ourselves"
+rm -f $KERNELTMP $DEVICEFILENAME $BOOTIMAGE
+echo "All done"
+
+
+In the above script actual image is generated by the following comand
+
+#mknbi -d ram -i rom -r rootfs.gz -k vmlinuz-nt -o img
+
+where:
+ rootfs.gz - minimal root file system (MRFS);
+ vmlinuz-nt - kernel;
+ img - resulting image.
+
+
+Note:
+Default ramdisk size is 4096. It was enough for RedHat4.1 based minimal file system, but
+apparently not enough for 5.2 based. When this happens "end request:I/O error, dev 01:00 ..."
+error shows up. To fix that either use "mknbi -a ramdisk_size=8192" to pass parameter to the
+kernel (doesn't require kernel recompilation), or change /usr/src/linux/drivers/block/rd.c:
+int rd_size= from 4096 to 8192 or whatever and rebuild the kernel.
+
+
+2.2.1. Kernel.
+
+Kernels 2.0.30 and 2.0.36 have been used by author, although nothing is preventing you from
+experimenting with others. Kernel should include ramdisk support. The following
+<link to .config> configuration has been used to build <link to binary (kernel 2.0.30)>.
+You may find some components unnecessary, just exclude them and rebuild.
+
+Don't forget to change root device after you built the kernel (rdev vmlinuz /dev/rd).
+
+Gotcha's: apparently smbfs is broken in 2.2.x kernels. Symptoms: remote share is mounted
+just fine but after a while fails with "smb_request: result = -32" errmsg. I've heard
+SuSe has fix for that.
+
+2.2.2. MRFS.
+
+Minimal root file system is required to get Linux up and running along with networking until
+it can mount remote file system to run X/Java from there. After image gets loaded from the
+server MRFS is decompressed into ramdisk. If you can afford a lot of ram on your terminal the
+entire remote file system can be moved to rootfs.gz. That will make your terminal more
+responsive.
+
+
+2.2.3. Building MRFS.
+
+Some folks found it easier to start from scratch, others use known "minimal" Linux distributions
+(Linux Router, tomsrtbt, etc.), yet others prefer to start from "big" Linuces like I did. Every
+path has it's pro and contras.
+
+Pruning standard distribution (RedHat, Debian, etc.) to your needs might be very time consuming.
+To ease that painful process I have used remotely booted diskless client with NFS-Root (see
+Etherboot's Readme, NFS-Root and NFS-Root-Client mini-HOWTO's, Diskless-HOWTO):
+
+- setup minimal RedHat4.1 install (networked workstation, X, no development, mail, etc., ~117MB);
+- find . -print|cpio -pmd /usr/NFS/ROOTFS - copy entire fs tree to NFS exported dir;
+- mknod /usr/NFS/ROOTFS/dev/nfsroot b 0 255;
+- build vmlinuz-nfs kernel according to NFS-Howto (built-in bootp,rarp,NFS,NFS root,NIC
+ driver,RAM disk);
+- rdev vmlinuz-nfs /dev/nfsroot - to set NFS root device;
+- build image for NFS-Root fs:
+ #mknbi -d rom -i rom -k vmlinuz-nfs -o nfsImage;
+- boot client while monitoring NFS file requests (by Solaris snoop);
+- copy files from /usr/NFS/ROOTFS to /usr/BOOT/ROOTFS (MRFS model) according to snoop's
+ filelist;
+- generate image by mkrootnet script (don't forget to point to the right kernel vmlinuz-nt).
+
+The above trick not only allows to determine the sought files set but also debug boot process
+analyzing NFS messages. I found it convenient to put "read tmp" statements into init scripts
+for debugging. Tracking files up until issuing login gives you <link to rootfs.gz> MRFS (~1MB)
+that can be used to boot Linux from ROM (flash, eprom, DiskOnChip, SanDisk, etc.) as well. All
+the other files requested by client (during starting X, Java, Java client) were put into (link
+to remotefs.zip, ~9MB).
+
+
+To restore MRFS model on your PC from the above rootfs.gz:
+- #cd /tmp
+- #gunzip rootfs.gz
+- #mount -o loop -t ext2 /tmp/rootfs /mnt
+- #cd /mnt
+- #find . -print|cpio -pmd /usr/BOOT/ROOTFS
+- #umount /mnt
+
+Note:
+
+You will have to change attributes of some dirs, files (/etc/mtab, /etc/mtab~, /var/lock/subsys/*,
+/var/run/*, /dev/tty*, etc.) against standard. This is because with standard attribs diskless
+client refused to work. For example I had to change /dev/tty* ownerships to 99:99 from original
+0:0 or 0:5, to get rid of errmsg "INIT: Id "1" respawning too fast: disabled for 5 minutes".
+Being admin illiterate I just chmod them to 777 and chown to 99:99 to make life easier.
+THIS IS SERIOUS SECURITY VIOLATION!!! Using keyboardless terminal with no daemons running in
+my case reduces the risk, yet I would appreciate very much those more experienced who will help
+to restore the right attribs while keeping the distribution working.
+
+Some "gotcha's" to watch for during MRFS building:
+- standard attributes/ownership of some files don't work;
+- rdev must be set (non-tagged image didn't work, so couldn't use config file to pass parrs
+ to the kernel);
+- diskless client writes 99:99 ownership on generated files;
+- "password incorrect" for root, but any other OK and su OK too.
+
+
+2.3. RemoteFS.
+
+Remotefs.zip file includes everything required by the system that can be located on
+remote file system, i.e after booting has been complete and remote file system mounted.
+In my case it is X Windows System and Java binaries, libraries etc. To use that file on
+MS Windows NT:
+- unzip remotefs.zip to some directory;
+- share this directory read-only as "usr" (or share as some other name and pass this name to
+ the client through bootptab configuration file for BOOTP server;
+- create an account username=root, password=linux on NT (can be set in bootptab).
+
+Note:
+There's no symbolic links on NTFS, so UNIX links must be replaced by copies on NTFS.
+To determine potential troublmakers one could use the following:
+- first copy required subset (according to snoop's intercept) from /usr/NFS/ROOTFS to
+ /usr/BOOT/REMOTEFS;
+- mount some share from NTFS to /mnt;
+- /usr/BOOT/REMOTEFS#find . -print|cpio -pmd /mnt 2>links;
+In the links file you will find names to work with.
+
+
+2.4. Booting sequence.
+
+Boot occurs in the following sequence:
+- bootprom sends bootp request,
+- bootp server responds with subnet mask, client's name, client's IP, TFTP server's IP,
+ bootfile name and some optional parameters (like NT's username/password to use it's share,
+ you could pass some other share name here as say T104="somedir");
+- bootprom downloads image from TFTP server;
+- kernel starts;
+- kernel decompresses MRFS in RAM;
+- system starts init using ramdisk root,
+- mounts remote file system from NT via SMBFS;
+- automatically logins;
+- starts xstart script located on remotefs (/usr/sbin) where you can start any of your
+ programs, change parameters, etc. without rebuilding the image.
+

+
+Gotcha's:
+Looks like smbmount client from smbfs package used to mount remote Windows shares to local
+Linux dirs in pre 2.2.x era isn't maintained anymore so you should use one coming with
+Samba package. Also binary smbmount won't work with 2.2.x, so you have to recompile with
+2.2.x headers following Samba's readme. Yet even that won't guarantee reliable work until
+somebody fixes kernel's smbfs module.
+
+2.4.1. BOOTP, TFTP.
+
+There are number of BOOTP, TFTP servers for Windows on the market. You could find them
+here:
+
+- www.walusoft.co.uk (Walusoft's tftp);
+- ftp.coast.net/simtel/nt/internet/tftpds12.zip (Millwood AB's tftp);
+- ftp.cabletron.com/pub/snmp/bootftp/boottft2.zip (Cabletron's bootp/tftp combo);
+- www.tellurian.au.com (Tellurian's bootp, tftp, dhcp servers).
+- www.metainfo.com (Metainfo's DHCP server)
+- www.nts.com (Network Telesystems's DHCP server in IPserver package)
+
+My choice was Tellurian's products - very reliable, simple to install, attractively priced
+(fully capable evaluation versions are available).
+
+2.5. Bootprom.
+
+Ken Yap's Etherboot <etherboot.sourceforge.net> will tell you everything about bootprom.
+Here I just want to mention that normally you would have to put bootprom's code into network
+adapter's PROM. But if your hardware like mine has BIOS programmed in flash you could
+re-program it to add bootprom (some BIOS requires special programmer to do that, others don't)
+as BIOS extension.
+
+This is what I did to add ne.rom (bootprom generated by Etherboot's makerom for NE2000 clone)
+to AMI BIOS on my flash:
+
+- read flash content by programmer into bios.bin binary file;
+- use one of available binary editors (say www.simtel.net/Win95/editors/hxp3005.zip to add
+ ne.rom to bios.bin (and to edit ne.rom if necessary);
+- write new bios.bin back to flash.
+
+Notes:
+- makerom generates bootprom for standard EPROM sizes (8k, 16k, 32k, etc.), so if you tight on
+ space use -s flag to adjust size (or cut it manually to multiple of 512 bytes blocks, just
+ don't forget to adjust extension's length which is coded in Byte 2 and checksum to 8 bits
+ of zero;
+- valid absolute addresses for BIOS extensions are from 0xC8000 to 0xF4000 (check with
+ motherboard's manufacturer how flash is mapped onto system memory space);
+- Byte 0 must be 0x55, Byte 1 must be 0xAA, Byte 2 must be extension's length in 512 bytes
+ blocks;
+- extension BIOS has to start at a 2k boundary;
+
+
+3. Resources.

+
+...
+
+2) I have added conditional code to main.c from Etherboot 5.0.4 to add
+a new default boot option and I have included the modified main.c as an
+attachment to this message.
+
+As I received Etherboot 5.0.4, in the Config file, if you select
+ASK_BOOT with a non zero time-out option, then you also get to set
+ANS_DEFAULT = ANS_NETWORK or ANS_DEFAULT = ANS_LOCAL to determine what
+will happen if the operator does not respond to the prompt. I have now
+added conditional code in main.c such that if you set ANS_DEFAULT =
+ANS_AUTO, the default answer will be set according to whether or not
+there is a hard disk in the system (as detected by the BIOS). If a hard
+disk is present, then if the operator does nothing, the system will boot
+from it. If a hard disk does not exist, then again if the operator does
+nothing, the system will boot via the network. Either way, for our
+particular environment, the operator has to do nothing to get it to boot
+correctly. Yet the operator can still override the default selection
+to, for example, allow a unit without a hard disk, to boot directly from
+a floppy rather than the network, or to allow a unit with a hard disk,
+to boot from the network.
+
+I don't know it the code I have added might be correct for a future
+production version of Etherboot, but I thought I'd send it to you and
+let you get it into the system if you feel it might be appropriate.
+
+Thanks,
+

+
+[Ed: On a compliant BIOS, it will actually boot the next device in the
+BIOS list if local is selected, either explicitly or by timeout, which
+may or may not be the hard disk, which is why it's less than general and
+not included in the distribution by default.]

+# Makefile for Etherboot
+#
+# Most of the time you should edit Config
+#
+# Common options:
+# VERSION=v - Set the version string
+#
+# NS8390 options:
+# -DINCLUDE_NE - Include NE1000/NE2000 support
+# -DNE_SCAN=list - Probe for NE base address using list of
+# comma separated hex addresses
+# -DINCLUDE_3C503 - Include 3c503 support
+# -DT503_SHMEM - Use 3c503 shared memory mode (off by default)
+# -DINCLUDE_WD - Include Western Digital/SMC support
+# -DWD_DEFAULT_MEM- Default memory location for WD/SMC cards
+# -DCOMPEX_RL2000_FIX
+#
+# If you have a Compex RL2000 PCI 32-bit (11F6:1401),
+# and the bootrom hangs in "Probing...[NE*000/PCI]",
+# try enabling this fix... it worked for me :).
+# In the first packet write somehow it somehow doesn't
+# get back the expected data so it is stuck in a loop.
+# I didn't bother to investigate what or why because it works
+# when I interrupt the loop if it takes more then COMPEX_RL2000_TRIES.
+# The code will notify if it does a abort.
+# SomniOne - somnione@gmx.net
+#
+# 3C509 option:
+# -DINCLUDE_3C509 - Include 3c509 support
+#
+# 3C90X options:
+# -DINCLUDE_3C90X - Include 3c90x support
+# -DCFG_3C90X_PRESERVE_XCVR - Reset the transceiver type to the value it
+# had initially just before the loaded code is started.
+# -DCFG_3C90X_XCVR - Hardcode the tranceiver type Etherboot uses.
+# -DCFG_3C90X_BOOTROM_FIX - If you have a 3c905B with buggy ROM
+# interface, setting this option might "fix" it. Use
+# with caution and read the docs in 3c90x.txt!
+#
+# See the documentation file 3c90x.txt for more details.
+#
+# CS89X0 (optional) options:
+# -DINCLUDE_CS89X0- Include CS89x0 support
+# -DCS_SCAN=list - Probe for CS89x0 base address using list of
+# comma separated hex addresses; increasing the
+# address by one (0x300 -> 0x301) will force a
+# more aggressive probing algorithm. This might
+# be neccessary after a soft-reset of the NIC.
+#
+# LANCE options:
+# -DINCLUDE_NE2100- Include NE2100 support
+# -DINCLUDE_NI6510- Include NI6510 support
+#

+#
+# I82586 options:
+# -DINCLUDE_3C507 - Include 3c507 support
+# -DINCLUDE_NI5210- Include NI5210 support
+# -DINCLUDE_EXOS205-Include EXOS205 support
+#
+# SMC9000 options:
+# -DINCLUDE_SMC9000 - Include SMC9000 driver
+# -DSMC9000_SCAN=list - List of I/O addresses to probe
+#
+# TIARA (Fujitsu Etherstar) options:
+# -DINCLUDE_TIARA - Include Tiara support

+# NI5010 options:
+# -DINCLUDE_NI5010 - Include NI5010 support
+#
+# TULIP options:

+# -DUSE_INTERNAL_BUFFER - receuve and transmit buffers within program
+# space, not below 0x10000, in case that region is used
+#
+# RTL8139 options:

+Subject: Etherboot on bare metal
+Date: Tue, 10 Apr 2001 23:19:19 +0200
+Organization: Prisma Engineering srl
+
+Hi Ken,
+I have ported Etherboot on an embedded, biosless platform and would like
+to contribute the code.
+
+Essentially, the hardware I was running Etherboot is a Pentium based
+embedded system, with an Intel Chipset, *but* without serial, VGA,
+keyboard etc., only an 82559 Intel (custom) Ethernet controller (I debug
+it with the etheral Ethernet packet analyser and an emulator).
+
+What I did was:
+
+ a.. integrate the init.s file within the firmware, with GDT
+(re)initialisation (a simple and single entry point taking control of
+the boot process)
+ b.. provide some stupid BIOS stubs in order to let the OS boot and
+still belive that an INT10 call goes to the BIOS
+ c.. provide some basic functions to Etherboot, like timer (I used the
+Pentium TSC internal counter)
+ d.. hardwire in the code information about the RAM size
+The BIOS stubs are enough to boot Linux, pSOS and QNX with bootp. QNX is
+somewhat difficult to load, because the i82559 driver tries to find the
+component using the BIOS32 calls, so I had to patch it.
+
+what i I got from the original firmware is the PCI initialisation and
+resource (I/O, interrupts, memory) allocation.
+
+I send you what I changed, that is, the initialisation code and the
+misc.c file containing the timer, and the makefile (I don't remember
+exactly the options I used to compile all).
+
+Of course, it is only a good starting point for anyone wanting to
+implement a bootp client on a biosless platform; some integration work
+still needs to be done.
+
+Ciao
+Paolo
+
+And in a subsequent email:
+
+I worked with version 4.6.12, but the real modifications involve the
+init.S file, which I think is quite sstable between releases. I forgot
+to say that my entry point (symbol _start in init.s) assumes the
+processor is already in protected mode.
+
+[The only difference between main.c and misc.c from those in Etherboot
+4.6.12 seems to be the deletion of eth_reset(). This may be of use to
+others trying to make these changes work on more recent releases. Ken]

+
+The 8-bit Intel Hex File Format is a printable ASCII format consisting of one
+ or more data records followed by an end of file record. Each
+record consists of one line of information. Data records may appear in any
+ order. Address and data values are represented as 2 or 4 hexadecimal
+digit values.
+
+Record Format
+:LLAAAARRDDDD......DDDDCC
+
+
+LL
+AAAA
+RR
+DD
+CC
+Length field. Number of data bytes.
+Address field. Address of first byte.
+Record type field. 00 for data and 01 for end of record.
+Data field.
+Checksum field. One's complement of length, address, record type and data
+ fields modulo 256.
+CC = LL + AAAA + RR + all DD = 0
+
+Example:
+:06010000010203040506E4
+:00000001FF
+
+The first line in the above example Intel Hex file is a data record addressed
+ at location 100H with data values 1 to 6. The second line is the end

+Running Etherboot within Bochs
+==============================
+
+Michael Brown <mbrown@fensystems.co.uk>
+Based on an idea suggested by H. Peter Anvin <hpa@zytor.com>.
+
+$Id$
+
+Bochs is a program that simulates a complete Intel x86 computer,
+including hardware. It can be used to test Etherboot. There is a
+special pseudo NIC ("pnic") implemented in Bochs, with a corresponding
+driver in Etherboot. (There is also an NE2000 ISA driver in Bochs,
+but it doesn't seem to quite work.)
+
+To get bochs running is fairly simple:
+
+1. Get the bochs source code:
+ a) cvs -d:pserver:anonymous:@cvs.sourceforge.net:/cvsroot/bochs login
+ b) cvs -d:pserver:anonymous:@cvs.sourceforge.net:/cvsroot/bochs co bochs
+
+2. Configure bochs with
+ ./configure --enable-all-optimisations --enable-pci \
+ --enable-ne2000 --enable-pnic
+ Other potentially useful configure options:
+ --prefix=/usr
+ to force use of standard file locations
+ --enable-debugger
+ to enable the internal debugger
+
+3. Build bochs:
+ make
+
+4. Configure Etherboot with CONFIG_PCI_DIRECT: add the line
+ CFLAGS += -DCONFIG_PCI_DIRECT
+ to the end of src/arch/i386/Config.
+
+5. Build bin/pnic.zrom:
+ make bin/pnic.zrom
+
+6. Load the TUN/TAP kernel module:
+ modprobe tun
+ You should see the device /dev/net/tun is created automatically if
+ you're using devfs, otherwise you may have to create it by hand with:
+ mknod /dev/net/tun c 10 200
+
+7. Grant yourself write access to /dev/net/tun:
+ su -c 'chown <your user id> /dev/net/tun'
+ The alternative to this is to run Bochs as root. Don't do that.
+
+8. Add the following fragment to /etc/dhcpd.conf:
+ subnet 10.254.254.0 netmask 255.255.255.252 {
+ range dynamic-bootp 10.254.254.1 10.254.254.1;
+ }
+ You will also need to add in any of your usual declarations for
+ Etherboot, e.g. 'filename "vmlinuz.ltsp";'. Note that this setup
+ assumes that your DHCP server, TFTP server etc. all live on the
+ machine you are using for running Bochs. If not, then you're on
+ your own.
+
+9. Change back to this directory and run bochs from your Bochs source tree:
+ cd /path/to/Etherboot/contrib/bochs
+ /path/to/bochs/source/tree/bochs
+
+10. Select option 5 (Begin simulation). You will be prompted for your
+ root password. This is required in order to configure the tun1
+ network interface and to restart the DHCP server.
+
+11. You should see Bochs start up and attempt to boot from the network,
+ with a screen that looks like:

+
+
+
+
+Serial console
+==============
+
+You can use the program "serial-console" to obtain a virtual serial
+console for Etherboot running within Bochs. Simply run
+"./serial-console" on a spare tty (e.g. a separate xterm window)
+before starting Bochs, and ensure that you have compiled Etherboot
+with appropriate settings such as
+ CFLAGS+= -DCONSOLE_DUAL -DCOMCONSOLE=0x3F8 -DCONSPEED=9600
+
+There is a manual page for "serial-console"; use
+"man ./serial-console.1" to view it.
+
+
+
+TODO
+====
+
+Packet forwarding/masquerading - document what must be set up.
+
+Mention possibility of using RFB as the display device - in
+conjunction with the serial console, gives you a test facility that
+can be accessed remotely.
+
+Mention use of BOCHSBP instruction (xchgw %bx,%bx) to avoid need to
+calculate breakpoints.

+# CONFIG_INTERFACE
+#
+# The configuration interface is a series of menus or dialog boxes that
+# allows you to change all the settings that control Bochs's behavior.
+# There are two choices of configuration interface: a text mode version
+# called "textconfig" and a graphical version called "wx". The text
+# mode version uses stdin/stdout and is always compiled in. The graphical
+# version is only available when you use "--with-wx" on the configure
+# command. If you do not write a config_interface line, Bochs will
+# choose a default for you.
+#
+# NOTE: if you use the "wx" configuration interface, you must also use
+# the "wx" display library.

+#=======================================================================
+# DISPLAY_LIBRARY
+#
+# The display library is the code that displays the Bochs VGA screen. Bochs
+# has a selection of about 10 different display library implementations for
+# different platforms. If you run configure with multiple --with-* options,
+# the display_library command lets you choose which one you want to run with.
+# If you do not write a display_library line, Bochs will choose a default for
+# you.
+#
+# The choices are:
+# x use X windows interface, cross platform
+# win32 use native win32 libraries
+# carbon use Carbon library (for MacOS X)
+# beos use native BeOS libraries
+# macintosh use MacOS pre-10
+# amigaos use native AmigaOS libraries
+# sdl use SDL library, cross platform
+# svga use SVGALIB library for Linux, allows graphics without X11
+# term text only, uses curses/ncurses library, cross platform
+# rfb provides an interface to AT&T's VNC viewer, cross platform
+# wx use wxWindows library, cross platform
+# nogui no display at all

+# CDROMD:
+#
+# cdromd: dev=/dev/cdrom, status=inserted
+# cdromd: dev=/dev/cdrom, status=ejected
+# cdromd: dev=e:, status=ejected
+#
+# In windows, the drive letter + colon notation should be used for cdroms.
+# Depending on versions of windows and drivers, you may only be able to
+# access the "first" cdrom in the system. On MacOSX, use path="drive"
+# to access the physical drive.
+#
+# NOTE: diskd and cdromd must not be used together!
