What is Bochs?

|
Bochs is a portable x86 PC emulation software package that emulates
|
|
|
|
|
enough of the x86 CPU, related AT hardware, and BIOS to run DOS,
|
|
|
|
|
Windows '95, Minix 2.0, and other OS's, all on your workstation.

Bochs is an open source project distributed under the <a
|
2001-05-09 05:44:39 +04:00
|
|
|
href="http://www.gnu.org/copyleft/lesser.html">GNU Lesser General Public License</a>. It was originally a commercial product, but in March 2000
|
2001-05-09 04:25:47 +04:00
|
|
|
<a href="www.linux-mandrake.com">MandrakeSoft</a> bought Bochs and committed it
|
|
|
|
|
to Open Source. <a href="http://www.linux-mandrake.com/en/announce-bochs-20000323.php3">Here</a> is the press release.

Bochs now compiles/runs on many platforms. See the following list
|
|
|
|
|
for supported platforms and special notes:
|
|
|
|
|
<UL>
|
|
|
|
|
<LI><B>Unix/X11:</B> This is my main development platform.
|
|
|
|
|
<LI><B>BeOS:</B> I also did this port, originally to R3/PPC using
|
|
|
|
|
CodeWarrior. It now works on R4/x86 with egcs. Simon Huet
|
|
|
|
|
picked up maintaining/reworking the BeOS GUI port. Check
|
|
|
|
|
out Simon's
|
|
|
|
|
<A HREF="http://members.xoom.com/bebochs/">BeBochs</A> page.
|
|
|
|
|
<LI><B>Win32:</B> This port was done by David Ross. I've enhanced the build
|
|
|
|
|
process for Win32. You can compile with either the MS Visual C++ 5.0 or
|
|
|
|
|
GNU-Win32 environments. Go to <A HREF="win32.html">Compiling Bochs on Win32</A>
|
|
|
|
|
<LI><B>OS/2:</B> Nick Behnken used PE2LX to translate David Ross's Win32 port
|
|
|
|
|
to an OS/2 program. Check out
|
|
|
|
|
<A HREF="http://www.htc.net/~nbehnken">Nick Behnken's page</A>.
|
|
|
|
|
<LI><B>OS/2:</B> Craig Ballantyne ported bochs to OS/2. I will
|
|
|
|
|
integrate this back into the main bochs source soon. Check out the
|
|
|
|
|
<A HREF="http://www.guisoft-corp.com">guiSoft Corp. home page</A>.

ported bochs to the Mac. His changes are integrated, though it
|
2001-04-10 05:04:59 +04:00
|
|
|
is work in progress. He compiled with CodeWarrior Pro R1 (CW12),
|
|
|
|
|
and included a project file 'Bochs.proj' in the top-level directory
|
|
|
|
|
of source code, which you may need to modify. I added
|
|
|
|
|
a '--with-macos' option to configure, so you can use a Unix
|
|
|
|
|
machine to generate header files for the Mac.
|
|

|
David has not had time to maintain the page or the Mac port since early
|
|
|
|
|
2000. If you have Mac development tools and want to contribute, contact
|
|
|
|
|
the developers list.

<LI><B>FreeDOS for Bochs:</B>
|
|
|
|
|
David Batterham
|
|
|
|
|
also offers information on running FreeDOS inside of bochs.
|
|
|
|
|
You can download a disk image with a pre-installed copy of FreeDOS,
|
|
|
|
|
a completely free DOS-like operating system.

|
|

Here is a list of platforms on which Bochs has successfully
|
|
|
|
|
been compiled and run, starting as of version bochs-971118a.
|
|
|
|
|
Note that, Bochs will compile/run on many other platforms,
|
|
|
|
|
but I'm starting the list from scratch again. If you have
|
|
|
|
|
had success with Bochs, please let me know so that I can
|
|
|
|
|
add your platform to this list.

here is a table listing the status of bochs' ability to run
|
|
|
|
|
various Operating Systems. If you have run other ones not listed
|
|
|
|
|
here, or would like to see new ones, please send me email.

may have changed since it was last updated, and is provided

What can you do with Bochs?
|
|
|
|
|
</H1>
|
|
|
|
|
|
|
|
|
|
Bochs can be compiled and used in a variety of modes, some which are
|
|
|
|
|
still in development. The 'typical' use of bochs is to provide
|
|
|
|
|
complete x86 PC emulation, including the x86 processor, hardware devices,
|
|
|
|
|
and memory. This allows you to run OS's and software within the emulator on
|
|
|
|
|
your workstation, much like you have a machine inside of a machine. For
|
|
|
|
|
instance, let's say your workstation is a Unix/X11 workstation, but you
|
|
|
|
|
want to run Win'95 applications. Bochs will allow you to run Win'95
|
|
|
|
|
and associated software on your Unix/X11 workstation, displaying a
|
|
|
|
|
window on your workstation, simulating a monitor on a PC.
|
|
|
|
|
<P>
|
|
|
|
|
Currently, bochs emulates the x86 CPU completely in software, and
|
|
|
|
|
does not run any instructions natively, even if you are running it
|
|
|
|
|
on an x86 machine.
|
|
|
|
|
<P>
|
|
|
|
|
Bochs may be of interest to you for other special modes, or uses.
|
|
|
|
|
You may wish to use only the device models included with bochs in
|
|
|
|
|
combination with your own CPU emulation, use it's CPU emulation
|
|
|
|
|
with another set of device models, use it's built in non-intrusive
|
|
|
|
|
debugger, co-emulate the bochs CPU model against another CPU
|
|
|
|
|
emulator/simulator, or use data compiled from instrumentation
|
|
|
|
|
facilities to analyze use of the x86 instruction set.
|
|
|
|
|
<P>
|
|
|
|
|
In addition to running x86 software on your workstation,
|
|
|
|
|
bochs may be of interest to x86 clone projects, x86 device driver
|
|
|
|
|
development teams, PC hardware development, and many other uses.
