I traced through my rom image.  at t=511471, the BIOS jumps to 10:4000 
(selector 16 starts at 0, so it's jumping into very low memory, where it was 
busy putting something earlier.  I think it was decompressing something there 
from the looks of the trace and the map file.)

Once at 0x04000, it outputx 0x13 to port 0x80 and seems to commit suicide 
shortly thereafter.

I'll send you what I have offlist.
