Bochs for Windows displaying HAL91 (Linux)

Bochs is a portable open source x86 and AMD64 PCs emulator mostly written in C++ and distributed under GNU Lesser General Public License.

Bochs is mostly used for operating system development (when an emulated operating system crashes, it does not crash the host operating system, so the emulated OS can be debugged) and to run other guest operating systems inside already running host operating systems. Some people use it to run old computer games inside their non-compatible computers. To meet Wikipedias quality standards, this article or section may require cleanup. ...

A Windows CE developer operating under the pseudonym "Mamaich" ported BOCHS as a proof of concept to the embedded Microsoft platform, taking the port through the 1.x release with his final public build being based upon the BOCHS 2.1.1 source tree. The release, aimed at the ARM architecture (specifically the SA1110 and PXA25x variants) demonstrated the increased power present in modern PDA devices, allowing for - at least as a proof of concept - an IA32 environment to be emulated on-top of the ARM architecture. Mamaich's distribution vanished from the Internet in mid-2005 and can now be downloaded from HPC:Factor.

Use

Bochs can emulate the hardware needed by the guest operating system, including hard drives, CD drives, and floppy drives. Disk and ISO images can be "inserted" while the system is being run. However, the system performance is very slow due to the fact that it is only emulated. It doesn't provide any CPU virtualization features.
