Un Identifiable Motherboard

I have a 486 motherboard and it has not model number what so ever. Can someone please help me identify it?

Is it up and running, if so use "sissoftsandra" and check the system board. If not running look at the biggest chips on it not counting the cpu and that should tell you what the north/southbrides are which should tell you the chipset, good a place as any to start.

on startup you should be able to see what bios you run and cross reference it online with what boards run that bios and the revision.
