Dont know if anyone can help, I've used hwinfo and it can only tell me the chipset:
UMC UM8881F

On the board is written:
UM880PAIO Rev 1.0

The BIOS is phoenix A013216

Wim's bios page mentions some boards useing UMC chipsets with similar names as possibly being Mustek but this is followed by a question mark. Would this be the Mustek known for scanners? I can find no mention of mobo's on there site. Any ideas who uses that kind of ID?
