Well the system is sacrificed and I got quite far with a 28F001 DIP part in a
ZIF zocket. Unfortunately I connected +15 to the wrong pin (off by one
errors in hardware are often more damaging than in software) last night and
fried something. I had RAM initialized properly now (I think) and ramtest
was executing the load part. Unfortunately the SuperIO (SMC FDC37N958FR)
seems to have a watchdog in the internal 8051 core and the 8051 firmware does
not follow SMSC's recommended mailbox protocols so I can't shut it off
directly. <grrrrr>
Does anyone have a P5-class ICE I can borrow? :-) Bochs doesn't get far
enough running the original BIOS to see how the mailbox registers are
accessed. I had hacked it to spit out any I/O accesses but I have to do a
lot of work in getting the tx chipset more fully emuated before the original
BIOS will get to the part where it talks to the 8051 core. :-(
