Manual(s):
Found the manual! But how do I attach it? 🤔 When trying to upload I get the message that ZIP and PDF are not allowed.

Motherboard BIOS(es):
Interestingly mine has an AMI BIOS (as opposed to Award) but unfortunately the "Low" EPROM seems to be damaged.

You have to upload your manual to another platform (mega, mediafire, whatever ...)

Ah. Sorry about that. I temporarily put it on my private webspace:
http://westarps.de/temp/PpmUy2sbApBdRG2 ... Manual.pdf

Would appreciate a short info if it's no longer needed so I can pull the file. Thanks!! :-)

(Note: This URL works. But as I do not currently use an SSL certificate Chrome will block this URL because of mixed encryption content. It may be necessary to manually copy the URL into the address bar.)

I've also added a picture of my board if that's of any interest.

It's such a shame that your board has a bad ROM because I think it has an AMI bios. AMI bios even from this era means that the manufacturer has put their id in the bios so we can find who made this board ...

Unless you can somehow get it to POST with that bad ROM ? If so please show us the POST string and attempt to dump the bios using software instead :D


By the way I've added the manual to the presentation. I'm going to upload the photo shortly :)

Yes, it's very frustrating. 😕 I'm very curious myself. Unfortunately the board does not currently POST. I have tried the usual to no avail including flashing the Award version off your site and one version off a different board with similar chipset. Nothing worked. The CPU and the VGA card are warming up but no signal and nothing from the PC speaker. I have now ordered a POST diagnostics card via eBay which has yet to arrive. Not optimistic, though. :-/

I could manage to dump the HIGH (odd) part:

When I try to dump the LOW (even) part the reader complains about a bad pin. When I force it to read the module it appears to be completely empty (FF...). I have tried to lower the voltage below the rated voltage / cool it / heat it slightly... nothing worked.
