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.
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.)
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.
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.
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
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.

In general iPXE files are licensed under the GPL. For historical
reasons, individual files may contain their own licence declarations.
Most builds of iPXE do not contain all iPXE code (in particular, most
builds will include only one driver), and so the overall licence can
vary depending on what target you are building.
The resultant applicable licence(s) for any particular build can be
determined by using "make bin/xxxxxxx.yyy.licence"; for example:
make bin/rtl8139.rom.licence
to determine the resultant licence(s) for the build bin/rtl8139.rom

ROM-o-matic web interface for building iPXE ROMs
------------------------------------------------
This web application generates iPXE images and sends them to a web
browser.
Available as part of the iPXE source code distribution, which can be
downlaoded from http://etherboot.org/
Author: Marty Connor <mdc@etherboot.org>
License: GPLv2
Support: http://etherboot.org/mailman/listinfo/ipxe
Please send support questions to the iPXE mailing list
System Requirements
-------------------
- Apache web server
- PHP 4+
- Tools required to build iPXE installed on the server
- gcc, mtools, syslinux, perl, etc.
Setup
-----
As distributed, it is expected that the rom-o-matic source code
directory is in the contrib directory of a iPXE source distribution.
The easiest way to do this is to simply put a iPXE source distribution
in a web server accessible directory.
If this is not the case, you will need to either edit the file
"globals.php"
or create a file called
"local-config.php"
containing the following lines:
<?php
$src_dir = "../../src";
?>
Then change the line beginning "$src_dir = " to the path of your iPXE
source code tree.
To make build times shorter, before you run rom-o-matic for the first time
you should cd to the ipxe "src" directory and enter the following
commands:
$ make
$ make bin/NIC
This will pro-compile most object files and will make your rom-o-matic
builds much faster.
Running rom-o-matic from a web browser
--------------------------------------
Enter a URL like:
http://example.com/ipxe-1.x.x/contrib/rom-o-matic

#=======================================================================
# 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.
#=======================================================================
#config_interface: textconfig
#config_interface: wx
#=======================================================================
# 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 wxWidgets library, cross platform
# nogui no display at all
#
# NOTE: if you use the "wx" configuration interface, you must also use
# the "wx" display library.
#
# Specific options:
# Some display libraries now support specific option to control their
# behaviour. See the examples below for currently supported options.
#=======================================================================
#display_library: amigaos

# ROMIMAGE:
# The ROM BIOS controls what the PC does when it first powers on.
# Normally, you can use a precompiled BIOS in the source or binary
# distribution called BIOS-bochs-latest. The ROM BIOS is usually loaded
# starting at address 0xf0000, and it is exactly 64k long.
# You can also use the environment variable $BXSHARE to specify the
# location of the BIOS.
# The usage of external large BIOS images (up to 512k) at memory top is
# now supported, but we still recommend to use the BIOS distributed with
# Bochs. Now the start address can be calculated from image size.

# CPU:
# This defines cpu-related parameters inside Bochs:
#
# COUNT:
# Set the number of processors:cores per processor:threads per core
# when Bochs is compiled for SMP emulation.
# Bochs currently supports up to 8 threads running simultaniosly.
# If Bochs is compiled without SMP support, it won't accept values
# different from 1.
#
# RESET_ON_TRIPLE_FAULT:
# Reset the CPU when triple fault occur (highly recommended) rather than
# PANIC. Remember that if you trying to continue after triple fault the
# simulation will be completely bogus !
#
# IPS:
# Emulated Instructions Per Second. This is the number of IPS that bochs
# is capable of running on your machine. You can recompile Bochs with
# --enable-show-ips option enabled, to find your workstation's capability.
# Measured IPS value will then be logged into your log file or status bar
# (if supported by the gui).
#
# IPS is used to calibrate many time-dependent events within the bochs
# simulation. For example, changing IPS affects the frequency of VGA
# updates, the duration of time before a key starts to autorepeat, and
# the measurement of BogoMips and other benchmarks.
#
# Examples:
# Machine Mips
# ________________________________________________________________
# 2.1Ghz Athlon XP with Linux 2.6/g++ 3.4 12 to 15 Mips
# 1.6Ghz Intel P4 with Win2000/g++ 3.3 5 to 7 Mips
# 650Mhz Athlon K-7 with Linux 2.4.4/egcs-2.91.66 2 to 2.5 Mips

# This defines the type and characteristics of all attached ata devices:
# type= type of attached device [disk|cdrom]
# mode= only valid for disks [flat|concat|external|dll|sparse|vmware3]
# mode= only valid for disks [undoable|growing|volatile]
# path= path of the image

# translation=type of translation of the bios, only for disks [none|lba|large|rechs|auto]
# model= string returned by identify device command
# journal= optional filename of the redolog for undoable and volatile disks
#
# Point this at a hard disk image file, cdrom iso file, or physical cdrom
# device. To create a hard disk image, try running bximage. It will help you
# choose the size and then suggest a line that works with it.
#
# In UNIX it may be possible to use a raw device as a Bochs hard disk,
# but WE DON'T RECOMMEND IT. In Windows there is no easy way.
#
# 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.
#
# The path is always mandatory. For flat hard disk images created with
# bximage geometry autodetection can be used (cylinders=0 -> cylinders are
# calculated using heads=16 and spt=63). For other hard disk images and modes
# the cylinders, heads, and spt are mandatory.
#
# Default values are:
# mode=flat, biosdetect=auto, translation=auto, model="Generic 1234"
#
# The biosdetect option has currently no effect on the bios

# CLOCK:
# This defines the parameters of the clock inside Bochs:
#
# SYNC:
# TO BE COMPLETED (see Greg explanation in feature request #536329)
#
# TIME0:
# Specifies the start (boot) time of the virtual machine. Use a time
# value as returned by the time(2) system call. If no time0 value is
# set or if time0 equal to 1 (special case) or if time0 equal 'local',
# the simulation will be started at the current local host time.
# If time0 equal to 2 (special case) or if time0 equal 'utc',

# LOG:
# Give the path of the log file you'd like Bochs debug and misc. verbiage
# to be written to. If you don't use this option or set the filename to
# '-' the output is written to the console. If you really don't want it,
# make it "/dev/null" (Unix) or "nul" (win32). :^(
#
# Examples:
# log: ./bochs.out
# log: /dev/tty
#=======================================================================
#log: /dev/null
log: bochsout.txt
#=======================================================================
# LOGPREFIX:
# This handles the format of the string prepended to each log line.
# You may use those special tokens :
# %t : 11 decimal digits timer tick
# %i : 8 hexadecimal digits of cpu current eip (ignored in SMP configuration)
# %e : 1 character event type ('i'nfo, 'd'ebug, 'p'anic, 'e'rror)
# %d : 5 characters string of the device, between brackets
#
# Default : %t%e%d

#=======================================================================
# LOG CONTROLS
#
# Bochs now has four severity levels for event logging.
# panic: cannot proceed. If you choose to continue after a panic,
# don't be surprised if you get strange behavior or crashes.
# error: something went wrong, but it is probably safe to continue the
# simulation.
# info: interesting or useful messages.
# debug: messages useful only when debugging the code. This may
# spit out thousands per second.
#
# For events of each level, you can choose to crash, report, or ignore.
# TODO: allow choice based on the facility: e.g. crash on panics from
# everything except the cdrom, and only report those.
#
# If you are experiencing many panics, it can be helpful to change
# the panic action to report instead of fatal. However, be aware
# that anything executed after a panic is uncharted territory and can
# cause bochs to become unstable. The panic is a "graceful exit," so
# if you disable it you may get a spectacular disaster instead.
#=======================================================================
panic: action=ask
error: action=report
info: action=report
debug: action=ignore
#pass: action=fatal
#=======================================================================
# DEBUGGER_LOG:
# Give the path of the log file you'd like Bochs to log debugger output.
# If you really don't want it, make it /dev/null or '-'. :^(
#
# Examples:
# debugger_log: ./debugger.out
#=======================================================================
#debugger_log: /dev/null
#debugger_log: debugger.out
debugger_log: -
#=======================================================================
# COM1, COM2, COM3, COM4:
# This defines a serial port (UART type 16550A). In the 'term' you can specify
# a device to use as com1. This can be a real serial line, or a pty. To use
# a pty (under X/Unix), create two windows (xterms, usually). One of them will
# run bochs, and the other will act as com1. Find out the tty the com1
# window using the `tty' command, and use that as the `dev' parameter.
# Then do `sleep 1000000' in the com1 window to keep the shell from
# messing with things, and run bochs in the other window. Serial I/O to
# com1 (port 0x3f8) will all go to the other window.
# Other serial modes are 'null' (no input/output), 'file' (output to a file
# specified as the 'dev' parameter), 'raw' (use the real serial port - under
# construction for win32), 'mouse' (standard serial mouse - requires
# mouse option setting 'type=serial' or 'type=serial_wheel') and 'socket'
# (connect a networking socket).
#
# Examples:
# com1: enabled=1, mode=null
# com1: enabled=1, mode=mouse
# com2: enabled=1, mode=file, dev=serial.out
# com3: enabled=1, mode=raw, dev=com1
# com3: enabled=1, mode=socket, dev=localhost:8888
#=======================================================================
#com1: enabled=1, mode=term, dev=/dev/ttyp9
#=======================================================================
# PARPORT1, PARPORT2:
# This defines a parallel (printer) port. When turned on and an output file is
# defined the emulated printer port sends characters printed by the guest OS
# into the output file. On some platforms a device filename can be used to
# send the data to the real parallel port (e.g. "/dev/lp0" on Linux, "lpt1" on
# win32 platforms).
#
# Examples:
# parport1: enabled=1, file="parport.out"
# parport2: enabled=1, file="/dev/lp0"
# parport1: enabled=0
#=======================================================================
parport1: enabled=1, file="parport.out"
#=======================================================================
# SB16:
# This defines the SB16 sound emulation. It can have several of the
# following properties.
# All properties are in the format sb16: property=value
# midi: The filename is where the midi data is sent. This can be a
# device or just a file if you want to record the midi data.
# midimode:
# 0=no data
# 1=output to device (system dependent. midi denotes the device driver)
# 2=SMF file output, including headers
# 3=output the midi data stream to the file (no midi headers and no
# delta times, just command and data bytes)
# wave: This is the device/file where wave output is stored
# wavemode:
# 0=no data
# 1=output to device (system dependent. wave denotes the device driver)
# 2=VOC file output, incl. headers
# 3=output the raw wave stream to the file
# log: The file to write the sb16 emulator messages to.
# loglevel:
# 0=no log
# 1=resource changes, midi program and bank changes
# 2=severe errors
# 3=all errors
# 4=all errors plus all port accesses
# 5=all errors and port accesses plus a lot of extra info
# dmatimer:
# microseconds per second for a DMA cycle. Make it smaller to fix
# non-continuous sound. 750000 is usually a good value. This needs a
# reasonably correct setting for the IPS parameter of the CPU option.
#
# For an example look at the next line:
#=======================================================================
#sb16: midimode=1, midi=/dev/midi00, wavemode=1, wave=/dev/dsp, loglevel=2, log=sb16.log, dmatimer=600000
#=======================================================================
# VGA_UPDATE_INTERVAL:
# Video memory is scanned for updates and screen updated every so many
# virtual seconds. The default is 40000, about 25Hz. Keep in mind that
# you must tweak the 'cpu: ips=N' directive to be as close to the number
# of emulated instructions-per-second your workstation can do, for this
# to be accurate.
#
# Examples:
# vga_update_interval: 250000
#=======================================================================
vga_update_interval: 300000
# using for Winstone '98 tests
#vga_update_interval: 100000
#=======================================================================
# KEYBOARD_SERIAL_DELAY:
# Approximate time in microseconds that it takes one character to
# be transfered from the keyboard to controller over the serial path.
# Examples:
# keyboard_serial_delay: 200
#=======================================================================
keyboard_serial_delay: 250
#=======================================================================
# KEYBOARD_PASTE_DELAY:
# Approximate time in microseconds between attempts to paste
# characters to the keyboard controller. This leaves time for the
# guest os to deal with the flow of characters. The ideal setting
# depends on how your operating system processes characters. The
# default of 100000 usec (.1 seconds) was chosen because it works
# consistently in Windows.
#
# If your OS is losing characters during a paste, increase the paste
# delay until it stops losing characters.
#
# Examples:
# keyboard_paste_delay: 100000
#=======================================================================
keyboard_paste_delay: 100000
#=======================================================================
# MOUSE:
# This option prevents Bochs from creating mouse "events" unless a mouse
# is enabled. The hardware emulation itself is not disabled by this.
# You can turn the mouse on by setting enabled to 1, or turn it off by
# setting enabled to 0. Unless you have a particular reason for enabling
# the mouse by default, it is recommended that you leave it off.
# You can also toggle the mouse usage at runtime (control key + middle
# mouse button on X11, SDL, wxWidgets and Win32).
# With the mouse type option you can select the type of mouse to emulate.
# The default value is 'ps2'. The other choices are 'imps2' (wheel mouse
# on PS/2), 'serial', 'serial_wheel' (one com port requires setting
# 'mode=mouse') and 'usb' (3-button mouse - one of the USB ports must be
# connected with the 'mouse' device - requires PCI and USB support).
#
# Examples:
# mouse: enabled=1
# mouse: enabled=1, type=imps2
# mouse: enabled=1, type=serial
# mouse: enabled=0
#=======================================================================
mouse: enabled=0
#=======================================================================
# private_colormap: Request that the GUI create and use it's own
# non-shared colormap. This colormap will be used
# when in the bochs window. If not enabled, a
# shared colormap scheme may be used. Not implemented
# on all GUI's.
#
# Examples:
# private_colormap: enabled=1
# private_colormap: enabled=0
#=======================================================================
private_colormap: enabled=0
#=======================================================================
# fullscreen: ONLY IMPLEMENTED ON AMIGA
# Request that Bochs occupy the entire screen instead of a

# Examples:
# fullscreen: enabled=0
# fullscreen: enabled=1
#=======================================================================
#fullscreen: enabled=0

# ne2k: NE2000 compatible ethernet adapter
#
# Examples:
# ne2k: ioaddr=IOADDR, irq=IRQ, mac=MACADDR, ethmod=MODULE, ethdev=DEVICE, script=SCRIPT
#
# ioaddr, irq: You probably won't need to change ioaddr and irq, unless there
# are IRQ conflicts.
#
# mac: The MAC address MUST NOT match the address of any machine on the net.
# Also, the first byte must be an even number (bit 0 set means a multicast
# address), and you cannot use ff:ff:ff:ff:ff:ff because that's the broadcast
# address. For the ethertap module, you must use fe:fd:00:00:00:01. There may
# be other restrictions too. To be safe, just use the b0:c4... address.
#
# ethdev: The ethdev value is the name of the network interface on your host
# platform. On UNIX machines, you can get the name by running ifconfig. On
# Windows machines, you must run niclist to get the name of the ethdev.
# Niclist source code is in misc/niclist.c and it is included in Windows
# binary releases.
#
# script: The script value is optional, and is the name of a script that
# is executed after bochs initialize the network interface. You can use
# this script to configure this network interface, or enable masquerading.
# This is mainly useful for the tun/tap devices that only exist during
# Bochs execution. The network interface name is supplied to the script
# as first parameter
#
# If you don't want to make connections to any physical networks,
# you can use the following 'ethmod's to simulate a virtual network.
# null: All packets are discarded, but logged to a few files.
# arpback: ARP is simulated. Disabled by default.
# vde: Virtual Distributed Ethernet
# vnet: ARP, ICMP-echo(ping), DHCP and read/write TFTP are simulated.
# The virtual host uses 192.168.10.1.
# DHCP assigns 192.168.10.2 to the guest.
# TFTP uses the ethdev value for the root directory and doesn't
# overwrite files.

# KEYBOARD_MAPPING:
# This enables a remap of a physical localized keyboard to a
# virtualized us keyboard, as the PC architecture expects.
# If enabled, the keymap file must be specified.
#
# Examples:
# keyboard_mapping: enabled=1, map=gui/keymaps/x11-pc-de.map
#=======================================================================
keyboard_mapping: enabled=0, map=
#=======================================================================
# KEYBOARD_TYPE:
# Type of keyboard return by a "identify keyboard" command to the
# keyboard controler. It must be one of "xt", "at" or "mf".
# Defaults to "mf". It should be ok for almost everybody. A known
# exception is french macs, that do have a "at"-like keyboard.
#
# Examples:
# keyboard_type: mf
#=======================================================================
#keyboard_type: mf
#=======================================================================
# USER_SHORTCUT:
# This defines the keyboard shortcut to be sent when you press the "user"
# button in the headerbar. The shortcut string is a combination of maximum
# 3 key names (listed below) separated with a '-' character. The old-style
# syntax (without the '-') still works for the key combinations supported
# in Bochs 2.2.1.
# Valid key names:
# "alt", "bksl", "bksp", "ctrl", "del", "down", "end", "enter", "esc",
# "f1", ... "f12", "home", "ins", "left", "menu", "minus", "pgdwn", "pgup",
# "plus", "right", "shift", "space", "tab", "up", and "win".
#
# Example:
# user_shortcut: keys=ctrl-alt-del
#=======================================================================
user_shortcut: keys=ctrl-alt-del
#=======================================================================
# I440FXSUPPORT:
# This option controls the presence of the i440FX PCI chipset. You can
# also specify the devices connected to PCI slots. Up to 5 slots are
# available now. These devices are currently supported: ne2k, pcivga,
# pcidev and pcipnic. If Bochs is compiled with Cirrus SVGA support
# you'll have the additional choice 'cirrus'.
#
# Example:
# i440fxsupport: enabled=1, slot1=pcivga, slot2=ne2k
#=======================================================================
i440fxsupport: enabled=1, slot1=pcipnic
#i440fxsupport: enabled=1, slot1=ne2k
#=======================================================================
# USB1:
# This option controls the presence of the USB root hub which is a part
# of the i440FX PCI chipset. With the portX option you can connect devices
# to the hub (currently supported: 'mouse' and 'keypad'). If you connect
# the mouse to one of the ports and use the mouse option 'type=usb' you'll
# have a 3-button USB mouse.
#
# Example:
# usb1: enabled=1, port1=mouse, port2=keypad
#=======================================================================
#usb1: enabled=1
#=======================================================================
# CMOSIMAGE:
# This defines image file that can be loaded into the CMOS RAM at startup.
# The rtc_init parameter controls whether initialize the RTC with values stored
# in the image. By default the time0 argument given to the clock option is used.
# With 'rtc_init=image' the image is the source for the initial time.
#
# Example:
# cmosimage: file=cmos.img, rtc_init=image
#=======================================================================
#cmosimage: file=cmos.img, rtc_init=time0

=head1 NAME
serial-console
=head1 SYNOPSIS
serial-console [options]
Options:
-h,--help Display brief help message
-v,--verbose Increase verbosity
-q,--quiet Decrease verbosity
-l,--log FILE Log output to file
-r,--rcfile FILE Modify specified bochsrc file
=head1 DESCRIPTION
C<serial-console> provides a virtual serial console for use with
Bochs. Running C<serial-console> creates a pseudo-tty. The master
side of this pty is made available to the user for interaction; the
slave device is written to the Bochs configuration file
(C<bochsrc.txt>) for use by a subsequent Bochs session.
=head1 EXAMPLES
=over 4
=item C<serial-console>
Create a virtual serial console for Bochs, modify C<bochsrc.txt>
appropriately.
=item C<serial-console -r ../.bochsrc -l serial.log>
Create a virtual serial console for Bochs, modify C<../.bochsrc>
appropriately, log output to C<serial.log>.
=back
=head1 INVOCATION
Before starting Bochs, run C<serial-console> in a different session
(e.g. a different xterm window). When you subsequently start Bochs,
anything that the emulated machine writes to its serial port will
appear in the window running C<serial-console>, and anything typed in
the C<serial-console> window will arrive on the emulated machine's
serial port.
You do B<not> need to rerun C<serial-console> afresh for each Bochs
session.
=head1 OPTIONS
=over 4
=item B<-l,--log FILE>
Log all output (i.e. everything that is printed in the
C<serial-console> window) to the specified file.
=item B<-r,--rcfile FILE>
Modify the specified bochsrc file. The file will be updated to
contain the path to the slave side of the psuedo tty that we create.
The original file will be restored when C<serial-console> exits. The
default is to modify the file C<bochsrc.txt> in the current directory.
To avoid modifying any bochsrc file, use C<--norcfile>.

Etherboot/NILO i386 initialisation path and external call interface
===================================================================
1. Background
GCC compiles 32-bit code. It is capable of producing
position-independent code, but the resulting binary is about 25%
bigger than the corresponding fixed-position code. Since one main use
of Etherboot is as firmware to be burned into an EPROM, code size must
be kept as small as possible.
This means that we want to compile fixed-position code with GCC, and
link it to have a predetermined start address. The problem then is
that we must know the address that the code will be loaded to when it
runs. There are several ways to solve this:
1. Pick an address, link the code with this start address, then make
sure that the code gets loaded at that location. This is
problematic, because we may pick an address that we later end up
wanting to use to load the operating system that we're booting.
2. Pick an address, link the code with this start address, then set up
virtual addressing so that the virtual addresses match the
link-time addresses regardless of the real physical address that
the code is loaded to. This enables us to relocate Etherboot to
the top of high memory, where it will be out of the way of any
loading operating system.
3. Link the code with a text start address of zero and a data start
address also of zero. Use 16-bit real mode and the
quasi-position-independence it gives you via segment addressing.
Doing this requires that we generate 16-bit code, rather than
32-bit code, and restricts us to a maximum of 64kB in each segment.
There are other possible approaches (e.g. including a relocation table
and code that performs standard dynamic relocation), but the three
options listed above are probably the best available.
Etherboot can be invoked in a variety of ways (ROM, floppy, as a PXE
NBP, etc). Several of these ways involve control being passed to
Etherboot with the CPU in 16-bit real mode. Some will involve the CPU
being in 32-bit protected mode, and there's an outside chance that
some may involve the CPU being in 16-bit protected mode. We will
almost certainly have to effect a CPU mode change in order to reach
the mode we want to be in to execute the C code.
Additionally, Etherboot may wish to call external routines, such as
BIOS interrupts, which must be called in 16-bit real mode. When
providing a PXE API, Etherboot must provide a mechanism for external
code to call it from 16-bit real mode.
Not all i386 builds of Etherboot will want to make real-mode calls.
For example, when built for LinuxBIOS rather than the standard PCBIOS,
no real-mode calls are necessary.
For the ultimate in PXE compatibility, we may want to build Etherboot
to run permanently in real mode.
There is a wide variety of potential combinations of mode switches
that we may wish to implement. There are additional complications,
such as the inability to access a high-memory stack when running in
real mode.
2. Transition libraries
To handle all these various combinations of mode switches, we have
several "transition" libraries in Etherboot. We also have the concept
of an "internal" and an "external" environment. The internal
environment is the environment within which we can execute C code.
The external environment is the environment of whatever external code
we're trying to interface to, such as the system BIOS or a PXE NBP.
As well as having a separate addressing scheme, the internal
environment also has a separate stack.
The transition libraries are:
a) librm
librm handles transitions between an external 16-bit real-mode
environment and an internal 32-bit protected-mode environment with
virtual addresses.
b) libkir
libkir handles transitions between an external 16-bit real-mode (or
16:16 or 16:32 protected-mode) environment and an internal 16-bit
real-mode (or 16:16 protected-mode) environment.
c) libpm
libpm handles transitions between an external 32-bit protected-mode
environment with flat physical addresses and an internal 32-bit
protected-mode environment with virtual addresses.
The transition libraries handle the transitions required when
Etherboot is started up for the first time, the transitions required
to execute any external code, and the transitions required when
Etherboot exits (if it exits). When Etherboot provides a PXE API,
they also handle the transitions required when a PXE client makes a
PXE API call to Etherboot.
Etherboot may use multiple transition libraries. For example, an
Etherboot ELF image does not require librm for its initial transitions
from prefix to runtime, but may require librm for calling external
real-mode functions.
3. Setup and initialisation
Etherboot is conceptually divided into the prefix, the decompressor,
and the runtime image. (For non-compressed images, the decompressor
is a no-op.) The complete image comprises all three parts and is
distinct from the runtime image, which exclude the prefix and the
decompressor.
The prefix does several tasks:
Load the complete image into memory. (For example, the floppy
prefix issues BIOS calls to load the remainder of the complete image
from the floppy disk into RAM, and the ISA ROM prefix copies the ROM
contents into RAM for faster access.)
Call the decompressor, if the runtime image is compressed. This
decompresses the runtime image.
Call the runtime image's setup() routine. This is a routine
implemented in assembly code which sets up the internal environment
so that C code can execute.
Call the runtime image's arch_initialise() routine. This is a
routine implemented in C which does some basic startup tasks, such
as initialising the console device, obtaining a memory map and
relocating the runtime image to high memory.
Call the runtime image's arch_main() routine. This records the exit
mechanism requested by the prefix and calls main(). (The prefix
needs to register an exit mechanism because by the time main()
returns, the memory occupied by the prefix has most likely been
overwritten.)
When acting as a PXE ROM, the ROM prefix contains an UNDI loader
routine in addition to its usual code. The UNDI loader performs a
similar sequence of steps:
Load the complete image into memory.
Call the decompressor.
Call the runtime image's setup() routine.
Call the runtime image's arch_initialise() routine.
Call the runtime image's install_pxe_stack() routine.
Return to caller.
The runtime image's setup() routine will perform the following steps:
Switch to the internal environment using an appropriate transition
library. This will record the parameters of the external
environment.
Set up the internal environment: load a stack, and set up a GDT for
virtual addressing if virtual addressing is to be used.
Switch back to the external environment using the transition
library. This will record the parameters of the internal
environment.
Once the setup() routine has returned, the internal environment has been
set up ready for C code to run. The prefix can call C routines using
a function from the transition library.
The runtime image's arch_initialise() routine will perform the
following steps:
Zero the bss
Initialise the console device(s) and print a welcome message.
Obtain a memory map via the INT 15,E820 BIOS call or suitable
fallback mechanism. [not done if libkir is being used]
Relocate the runtime image to the top of high memory. [not done if
libkir is being used]
Install librm to base memory. [done only if librm is being used]
Call initialise().
Return to the prefix, setting registers to indicate to the prefix
the new location of the transition library, if applicable. Which
registers these are is specific to the transition library being
used.
Once the arch_initialise() routine has returned, the prefix will
probably call arch_main().

* to make this code not be too annoying. (Where do you

* Since this function is actually just a callback from
* the network data transfer code, we need to be able to
* work with the data as it comes in. There is no chance
* for doing a seek other than forwards.
*
* The process we use is to first load the section
* headers. Once they are loaded (shdr != 0) we then
* look for where the symbol table and symbol table
* strings are and setup some state that we found
* them and fall into processing the first one (which
* is the symbol table) and after that has been loaded,
* we try the symbol strings. Note that the order is
* actually required as the memory image depends on
* the symbol strings being loaded starting at the
* end of the symbol table. The kernel assumes this
* layout of the image.
*
* At any point, if we get to the end of the load file
* or the section requested is earlier in the file than
* the current file pointer, we just end up falling
* out of this and booting the kernel without this

* Poll for received packets
*
* @v netdev Network device
*
* Fun, fun, fun. UNDI drivers don't use polling; they use
* interrupts. We therefore cheat and pretend that an interrupt has
* occurred every time undinet_poll() is called. This isn't too much
* of a hack; PCI devices share IRQs and so the first thing that a
* proper ISR should do is call PXENV_UNDI_ISR to determine whether or
* not the UNDI NIC generated the interrupt; there is no harm done by
* spurious calls to PXENV_UNDI_ISR. Similarly, we wouldn't be
* handling them any more rapidly than the usual rate of
* undinet_poll() being called even if we did implement a full ISR.
* So it should work. Ha!
*
* Addendum (21/10/03). Some cards don't play nicely with this trick,
* so instead of doing it the easy way we have to go to all the hassle
* of installing a genuine interrupt service routine and dealing with
* the wonderful 8259 Programmable Interrupt Controller. Joy.
*
* Addendum (10/07/07). When doing things such as iSCSI boot, in
* which we have to co-operate with a running OS, we can't get away
* with the "ISR-just-increments-a-counter-and-returns" trick at all,
* because it involves tying up the PIC for far too long, and other
* interrupt-dependent components (e.g. local disks) start breaking.
* We therefore implement a "proper" ISR which calls PXENV_UNDI_ISR
* from within interrupt context in order to deassert the device
* interrupt, and sends EOI if applicable.
