Hi i recently got this beauty, wanna know more about her. There are almost none markings, just the "REV 2.2 1991,8.". The chipset is SIS85c401/2. Looked up whole net and didnt find anything even similar. Most of them have lower number of jumpers, this one has 16 of them... not sure if i want to put my 3V CPUs, since it probably only utilises 5V ones? Anyone knows ?

That board is from early 1992, so quite old. Of course it only supports 5 volts cpus. So put in an intel DX or DX2. 5 volts only.

If you have a way of dumping the BIOS, then you can possibly via the ID string identity who manufactured the board
