+ 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.

+gPXE LOG file
+
++ Development for gPXE was moved from SourceForge CVS to a git
+ repository on git.etherboot.org in the first half of the year 2007.
+
++ The gitweb interface for gPXE is available at:
+
+ http://git.etherboot.org/?p=gpxe.git
+
++ The gitweb interface largely obsoletes the LOG file that used to be
+ distributed with Etherboot.

+gPXE README File
+
+gPXE is an implementation of the PXE specification for network
+booting, with extensions to allow additional features such as booting
+via HTTP, iSCSI, and AoE.
+
+In generally, gPXE is compatible with the industry-standard PXE
+specification, and also supports Etherboot .nbi file loading and some
+additional protocols and features.
+
+For more detailed information about gPXE, please visit our project
+website at: http://etherboot.org/
+
+BUILDING gPXE IMAGE FROM SOURCE
+
+If you don't want to install development tools, and have access to the
+Web, you can get gPXE and Etherboot ROM images made on demand from
+http://rom-o-matic.net/
+
+If you would like to compile gPXE images from source, here are some tips.
+
+We normally compile gPXE images on x86, 32-bit Linux machines. It is
+possible to also use x86-64 machines. We use gcc compiler options to
+create 32-bit output.
+
+It is important to have the necessary software packages installed. A gcc-based
+toolchain is required.
+
+The following packages (at least) are required:
+
+ - a gcc tool chain (gcc 3.x or gcc 4.x)
+ - binutils
+ - perl
+ - syslinux
+ - mtools
+
+To test your environment, cd to the "src" directory and type:
+
+ make
+
+You should see a lot of output, and when it stops, the "bin" directory
+should be populated with gPXE images and object files.
+
+To learn more about what to build and how to use gPXE, please visit our
+project website at http://etherboot.org/ , particularly the "howto" section.
+
+CONTACTING US
+
+Pointers to our project mailing lists are on http://etherboot.org/

+Real-time help is often available on IRC on the #etherboot channel of
+irc.freenode.net.

+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 "check:"
+echo "- if tftp server's download dir mounted to /mnt"
+echo "- loopback device is built-in or loaded"
+echo "\n press Enter when done"
+read tmp
+UPLOAD="/mnt/tmp" # tftp server's dir to upload bootimage
+echo -e "\nZeroing $DEVICEFILENAME of $FSBLOCKS k"
+echo "to be used as device for root filesystem model"
+dd if=/dev/zero of=$DEVICEFILENAME bs=1k count=$FSBLOCKS
+echo -e "\nMaking file system on $DEVICEFILENAME"
+mke2fs -m 0 $DEVICEFILENAME
+echo "Mounting $DEVICEFILENAME as a loopback device"
+mount -o loop -t ext2 $DEVICEFILENAME $MOUNT
+curdir=`pwd`
+cd $BOOTDISKDIR
+echo -e "Copying files from $BOOTDISKDIR to $DEVICEFILENAME, please wait"
+find . -print|cpio -pmd $MOUNT
+echo "Unmounting $MOUNT"
+umount $MOUNT
+cd $curdir
+echo "Copying $DEVICEFILENAME to $ROOTFS"
+dd if=$DEVICEFILENAME of=$ROOTFS bs=1k
+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;
+
+

+
+...
+
+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.]

+#
+# If you have a Compex RL2000 PCI 32-bit (11F6:1401),

+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]
