It was originally a commercial product, but in March 2000 <a href="www.linux-mandrake.com">MandrakeSoft</a> bought Bochs and committed itto Open Source. <a href="http://www.linux-mandrake.com/en/announce-bochs-20000323.php3">Here</a> is the press release.<P>Bochs now compiles/runs on many platforms. See the following listfor supported platforms and special notes:<UL><LI><B>Unix/X11:</B> This is my main development platform.<LI><B>BeOS:</B> I also did this port, originally to R3/PPC usingCodeWarrior. It now works on R4/x86 with egcs. Simon Huetpicked up maintaining/reworking the BeOS GUI port. Checkout Simon's<A HREF="http://members.xoom.com/bebochs/">BeBochs</A> page.<LI><B>Win32:</B> This port was done by David Ross. I've enhanced the buildprocess for Win32. You can compile with either the MS Visual C++ 5.0 orGNU-Win32 environments. Go to <A HREF="win32.html">Compiling Bochs on Win32</A><LI><B>OS/2:</B> Nick Behnken used PE2LX to translate David Ross's Win32 portto an OS/2 program. Check out<A HREF="http://www.htc.net/~nbehnken">Nick Behnken's page</A>.<LI><B>OS/2:</B> Craig Ballantyne ported bochs to OS/2. I willintegrate this back into the main bochs source soon. Check out the<A HREF="http://www.guisoft-corp.com">guiSoft Corp. home page</A>.<LI><B>Macintosh:</B>David Batterham<A HREF="mailto:drbatter@socs.uts.edu.au">drbatter@socs.uts.edu.au</A>or<A HREF="mailto:drbatter@yahoo.com">drbatter@yahoo.com</A>ported bochs to the Mac. His changes are integrated, though itis work in progress. He compiled with CodeWarrior Pro R1 (CW12),and included a project file 'Bochs.proj' in the top-level directoryof source code, which you may need to modify. I addeda '--with-macos' option to configure, so you can use a Unixmachine to generate header files for the Mac.Check out David's<A HREF="http://members.xoom.com/macbochs/">MacBochs website</A>.David has not had time to maintain the page or the Mac port since early2000. If you have Mac development tools and want to contribute, contactthe developers list.<LI><B>FreeDOS for Bochs:</B>David Batterhamalso offers information on running FreeDOS inside of bochs.You can download a disk image with a pre-installed copy of FreeDOS,a completely free DOS-like operating system.Check out his website at<A HREF="http://members.xoom.com/macbochs/freedos.html">http://members.xoom.com/macbochs/freedos.html.</A><BR>For more info about FreeDOS, see<A HREF="http://www.freedos.org/">FreeDOS Web page</A></UL><P>There's more! You can find more detailed testing information on the testing status pageon <a href="http://bochs.sourceforge.net">bochs.sourceforge.net</a>.<BR><HR><H1><A NAME="Platforms">Platforms:</A></H1>Here is a list of platforms on which Bochs has successfullybeen compiled and run, starting as of version bochs-971118a.Note that, Bochs will compile/run on many other platforms,but I'm starting the list from scratch again.

The 'typical' use of bochs is to providecomplete x86 PC emulation, including the x86 processor, hardware devices,and memory. This allows you to run OS's and software within the emulator onyour workstation, much like you have a machine inside of a machine. Forinstance, let's say your workstation is a Unix/X11 workstation, but youwant to run Win'95 applications. Bochs will allow you to run Win'95and associated software on your Unix/X11 workstation, displaying awindow on your workstation, simulating a monitor on a PC.<P>Currently, bochs emulates the x86 CPU completely in software, anddoes not run any instructions natively, even if you are running iton an x86 machine.<P>Bochs may be of interest to you for other special modes, or uses.You may wish to use only the device models included with bochs incombination with your own CPU emulation, use it's CPU emulationwith another set of device models, use it's built in non-intrusivedebugger, co-emulate the bochs CPU model against another CPUemulator/simulator, or use data compiled from instrumentationfacilities to analyze use of the x86 instruction set.<P>In addition to running x86 software on your workstation,bochs may be of interest to x86 clone projects, x86 device driverdevelopment teams, PC hardware development, and many other uses.</BODY></HTML>⌨️ 快捷键说明
