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.
