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

Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms.

Bochs includes emulation of the Intel x86 CPU, a custom BIOS and common I/O devices. Currently, Bochs can be compiled to emulate a 386, 486, Pentium/PentiumII/PentiumIII/Pentium4 or x86-64 CPU including optional SSEx, MMX, and 3DNow! instructions.

Bochs is capable of running most Operating Systems inside the emulation including Linux, Windows 95, DOS, and Windows NT 4. Bochs was written by Kevin Lawton and is currently maintained by this project.

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 OSes 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 Win95 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.
