I'm working on a x86 virtualization project and having a hard time with emulating the PC keyboard interface correctly. The problem is that the 8042-based keyboard controller interface is reasonably well documented, the 8042 chip itself is well documented, the AT and PS/2 keyboards are well documented, but no one seems to say what exactly the 8042 firmware does. Does anyone here know where I might obtain a ROM dump of a PC 8042-based keyboard controller? Doesn't really matter how old, though something with PS/2 mouse support would be best. Commented 8042 source code would of course be even better, but that's probably not likely... Thanks in advance for any info.

Das einzige mir bekannte veröffentlichte Tastatur-Bios befindet sich in dem Buch: "Hans-Joachim Blank: Single Chip PC, Verlag Markt und Technik 1992, Haar bei München". Das Buch sollte sich noch antiquarisch beschaffen lassen. Das Bios stammt von AWARD und wurde zwischen 1985 und 1990 gepflegt. Es liegt als Binärdatei vor. mfg
