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.>
|
||||

||||

||||
This program is free software; you can redistribute it and/or modify
|
||||

|
||||
(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
|
||||

|
||||
|
||||
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.

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.

reasons, individual files may contain their own licence declarations.

Most builds of iPXE do not contain all iPXE code (in particular, most

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.

# 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

# 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.

# 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

# 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

# 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

# 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,

# 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",

# 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
|

|

# 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.
|
||||
#
|

=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>.

\&\f(CW\*(C`serial\-console\*(C'\fR provides a virtual serial console for use with
|
||||
Bochs. Running \f(CW\*(C`serial\-console\*(C'\fR 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

Before starting Bochs, run \f(CW\*(C`serial\-console\*(C'\fR 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 \f(CW\*(C`serial\-console\*(C'\fR, and anything typed in
|

the \f(CW\*(C`serial\-console\*(C'\fR window will arrive on the emulated machine's

The original file will be restored when \f(CW\*(C`serial\-console\*(C'\fR exits. The

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().

* 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.
|

|

* Addendum (21/10/03). Some cards don't play nicely with this trick,

|

* 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.

/* Most documentation refers to the E820 buffer as being 20 bytes, and

* the API makes it perfectly legitimate to pass only a 20-byte buffer
|
||||
* and expect to get valid data. However, some morons at ACPI decided
|
||||
* to extend the data structure by adding an extra "extended
|
||||
* attributes" field and by including critical information within this
|
||||
* field, such as whether or not the region is enabled. A caller who
|
||||
* passes in only a 20-byte buffer therefore risks getting very, very
|
||||
* misleading information.
|
||||
*
|
||||
* I have personally witnessed an HP BIOS that returns a value of
|
||||
* 0x0009 in the extended attributes field. If we don't pass this
|
||||
* value through to the caller, 32-bit WinPE will die, usually with a
|
||||
* PAGE_FAULT_IN_NONPAGED_AREA blue screen of death.
|
||||
*
|
||||
* Allow a ridiculously large maximum value (64 bytes) for the E820
|
||||
* buffer as a guard against insufficiently creative idiots in the
