Hello Evasive,
it has been a long time but today I finally found the time to fiddle with this board again.
It POSTed and I took some pictures for you.

The attachment IMG_20250119_191119.jpg is no longer available
The BIOS itself looks rather sparse too:

The attachment IMG_20250119_191420.jpg is no longer available
Is there anything that I can do to help you identify this motherboard?
