Hi byte_76 and Jasa1063. I finally got this machine out of storage and dumped the BIOS. My BIOS was stored on an SST 29EE010 chip, contents here...

I hope this helps!

Hi SteveHere,

I’ve saved the revision D bios from my board if you would like to test it on yours.

Grab it from my thread here:

Troubleshooting 486 Motherboard

Do you have any 3.3V / 3.45V CPU’s to test in your board?
What behavior do you get from your board when you insert such a CPU without changing any other settings besides voltage?

My board is just dead. The power supply turns on but there is nothing on the post analyser card.
