Lessee, since the Basic Input Output System is burned into the CMOS
chips of an x86 and copied or 'mirrored' into DRAM during boot, I
spoze you could rewrite just about anything except the stuff like
the video ROM addresses of various peripherals. 

When I consider the size of Ralf Brown's INTERVUE database of
interrupts, I think the rewrite would be a daunting task. Although I
seem to recall numerous times when RTFM that I find mention of some
BIOS routines that have been rewritten by an executable. How much to
rewrite with improved routines is moot point.
