| − | | + | '''Bochs''' is an open-source [[Intel CPUs|386, 486 and Pentium emulator]] written in C++ geared around emulating the full [[wikipedia:x86|x86]] architecture. It does not have high emulation speeds because it emulates every x86 instruction and devices. |
| − | '''[[wikipedia:Bochs|Bochs]]''' is a free and open-source [[POS_(Pong_Consoles)_CPUs_and_Other_Chips#x86_CPUs|x86 CPU]] emulator written in C++ geared around emulating the full [[wikipedia:x86|x86]] architecture. It's designed to emulate every x86 instruction and device, prioritizing accuracy at the cost of speed. Its high accuracy, built-in debugger, support of recent x86-64 systems, and extensibility via plugins make it very useful for developing and testing operating systems and other low-level PC software. | |

| − | ==Overview==
| |
| − | Compared to [[QEMU]], Bochs focuses on portability and simplicity. Only x86 systems may be emulated. CPU emulation is performed through a generic interpreter, meaning it has been ported to non-x86 hosts. However, the results are very slow, and no virtualization technology is supported.
| |
| − | | |
| − | Unlike [[PCem]] which relies on BIOS ROMs to emulate actual machines, Bochs chose to create its own open-source BIOS to simulate a generic PC. Bochs also ships with the open-source SeaBIOS that is used in QEMU. Users may use their own BIOS images from actual machines, although the results are mixed and this is not officially supported.
| |
| − | | |
| − | Bochs cannot correctly emulate the speed or timing of older CPUs. The oldest CPU supported in the default builds is a Pentium (although as old as a 386 is supported by compiling with a custom ''enable-cpu-level'' flag), and selecting the oldest CPUs runs the same core as newer CPUs, just with the newer instructions disabled.
| |
| − | | |
| − | If one is interested in operating system development, this emulator is king. However, due to the slow speed, awkward user interface, and lack of gaming-centered features, you are better off using [[DOSBox]] for playing games, or a fork of [[PCem]] if full system emulation is needed.
| |
| − | | |
| − | Bochs has very rudimentary support for emulation of the FM Towns architecture via a fork, but development was abandoned long time ago so this can be used as an "FM Towns emulator" only for curiosity's sake. There are significantly better [[FM Towns emulators]] nowadays.
