Bochs is a highly portable open source IA-32 (x86) PC emulator
written in C++, that runs on most popular platforms. It includes emulation of the
Intel x86 CPU, common I/O devices, and a custom BIOS. Currently, Bochs can be compiled
2007-09-16 20:39:30 +04:00
to emulate a 386, 486, Pentium/PentiumII/PentiumIII/Pentium4 or x86-64 CPU including optional MMX,
SSEx and 3DNow! instructions.< BR >
2005-08-08 21:16:38 +04:00
Bochs is capable of running most Operating Systems inside the emulation including Linux, DOS,
2007-09-16 20:39:30 +04:00
Windows® 95/98 and Windows® NT/2000/XP or Windows Vista. Bochs was written by Kevin Lawton
and is currently maintained by this project.< BR >
2001-06-17 08:14:28 +04:00
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.

The Bochs community held an IRC open discussion chat on Sunday, February 1, 2004.
We talked about current and future developments (< a href = "irc-20040201.html" > Transcript< / a > ). Here are some transcripts of earlier conversations:

Bug Reports< / a > :
2001-06-17 08:14:28 +04:00
Mouse, interrupt controller,
timer, IDE controller, network card, keyboard, VGA... Most of our bug
reports and feature requests are due to incomplete C++ models of the
various PC devices. To improve this, we need PC Hardware Gurus who know
where to find the specs for this stuff and improve the hardware models for
Bochs. Working on models is a fun way to learn how things work, and unlike
designing a real hard disk, you can test out your changes on a real operating
system immediately!
