Linux (and some other software packages) use<a href="http://www.linuxsupportline.com/~billm/">wm-FPU-emu, written by Bill Metzenthen</a>. I modified the code to interface with bochs, withpermission from Bill.<p>To compile bochs to use this FPU emulator, grab the wm-FPU-emupackage from the bochs<A HREF="ftp://bochs.com/pub/">FTP site</A>,and extract it somewhere. This will create a directory called "math-emu". Supply the path tothis directory to the configure command in bochs, by includingthe option "--enable-fpu=/path/math-emu", where path is whereveryou extracted it.<p>Error reporting needs more work. Though, I havegot the paranoia tests to run on Linux running inside of bochslinked with wm-FPU-emu. They ran the same as on a realLinux/Pentium machine.<p>-Kevin</body></html>⌨️ 快捷键说明
