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 to emulate a 386, 486, Pentium, Pentium Pro or AMD64 CPU, including optional MMX, SSE, SSE2 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
- CPU / CPUDB
- Bugfixes for CPU emulation correctness (critical bugfix for x86-64 emulation)
- Memory type calculation support for Bochs debugger and instrumentation, to enable configure with
- CPUDB: Added Pentium (P54C) configuration to CPUDB
- CPUDB: Added Broadwell ULT configuration to CPUDB
- OS X 10.2 or later
