#: 120
Manufacturer/Identifier: IEI SSC-5X86H VER:C
Chipset : ALi 1487/1489
BIOS : Award Modular BIOS v4.51G
ID string : 06/28/96-ALI-1487/89-2A4KDD35C-00

Note that this image is a dump of the installed BIOS on my SBC, not an official update image from IEI.

The newer awdflash doesn't know how to backup this older award bios (happens quite often), as a result this is not a valid dump.
Can you please use UniFlash instead?
https://www.rainbow-software.org/uniflash/

Redumped the BIOS with Uniflash 1.40. Compared it with the original dump, and indeed, it looks like Awdflash only managed to dump half of it.

How do you go about verifying the new dump by the way? Can it be done with CBROM, Modbin, or something like that?

Attached the new dump. Will update the original post once it's verified.

Well actually that pointed to yet another board, so the end result is this:
https://theretroweb.com/motherboards/s/unknown-sih-486b
We have a manufacturer, yet another alias, bioses, manuals and pictures now. Oh and please, don't use stason links, find a TH99 mirror somewhere like this for instance:
https://arvutimuuseum.ee/th99/
There are many more out there. Stason is just an ad-ridden version of that.
