This is a SBC card:
Advantech PCA-6157 rev. A2. Takes Pentium 75 through 200 due to single plane 3.3V VRM. Takes async SRAM cache only, and based on 430FX chipset.

I'm trying to revive this card means needs missing bios firmware and keyboard controller replaced, manual for this card.

Keyboard controller is easy enough to get (AMIKEY-2), but firmware I have no luck with.

Here's this picture of what it looks like.

Thanks and cheers,

Super I/O seems to be a SMC FDC37C665, maybe try the AOpen AP5C, Gigabyte GA-586ATE/P, etc. those also have that same SIO.

Update, contacted Advantech directly and got the bios!

Also thank you for the manual.

I also asked Advantech about permission to make this bios and manual available to public domain, this is pending.

Cheers,

Great ! Wonder why they dropped those earlier bios off being downloadable, they do not take much space.
FWIW I tried to DL the manual direct from them but got an error, the driver files downloaded fine from them though....hmmm
