  Bochs - Wikipedia, the free encyclopedia
Bochs is a portable open source x86 and AMD64 PCs emulator mostly written in C++.
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.
Bochs can emulate the hardware needed by the guest operating system, including hard drives, cd drives, and floppy drives.

 bochs: The Open Source IA-32 Emulation Project (Home Page)
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.

 Review: VMWare Workstation 3.1 vs Virtual PC 4.3.2 vs Bochs 1.4 - OSNews.com
The open source Bochs, VMware Workstation by VMware, Inc. and VirtualPC from Connectix are applications that virtualize or emulate the x86 hardware, allowing you to run multiple operating systems on top of a "host" operating system that these three applications run upon.
Bochs emulates the x86 hardware and some of its peripherals, which makes it able to be easily portable among a number of platforms & architectures.
Bochs is not for everyone, as users must know a bit about their hardware.

Starting with Bochs 1.3, you can use environment variables in the bochsrc file, for example: diskc: file="$IMAGES/30M.sample", cyl=615, heads=6, spt=17 Starting with version 2.0, two environment variables have a built-in default value which is set at compile time.
Bochs has a selection of about 10 different display library implementations for different platforms.
This is the number of IPS that bochs is capable of running on your machine.

 Daemon News 199907 : Questions and Answers on Bochs with Kevin Lawton   (Site not responding. Last check: 2007-10-08)
Bochs is a pure emulator, in that it emulates everything: the CPU, IO devices, memory, etc. It's easiest to think about DOSEMU and Wine as API emulators.
Fortunately, emulation of the IO devices is also done in bochs, and it is this code which I'm moving over to the open source domain to be used in freemware.
I didn't base bochs on any prior work, though there were a couple major factors which made bochs possible, and still are major players.

 NewsForge | Getting started with Bochs
Bochs, an open source project, may be a better answer.
Bochs (pronounced "box") provides I/O emulation for a computer's standard parallel port, serial port, VGA card, disk, CD-ROM, timer chip, and network card, along with a custom BIOS.
The Bochs operating environment is regulated by a single file,.bochsrc, which resides in the base directory.

 FreeBSD on Bochs | Sig9
Since this experiment is going to be fairly complex and eventually consist of quite a few files, it's best to create a directory exclusively for this purpose, rather than clutter it up with the rest of your documents.
The Bochs configuration file specifies the location of disk images, details of the emulation layer and its virtual peripheral components (see bochsrc(5)).
Bochs makes it easier to test these changes without having to worry about messing up my desktop system or having to reboot.
