I have two PC Chips M912 motherboards which I got for free some years ago. One has PCB revision 1.4, the other is revision 1.7. I've seen 3 different jumper settings online which are supposedly for the AMD Am5x86, however none of them work. I power up the board, but there is no display shown on the monitor. This motherboard came with the following AMI BIOS revision,
BIOS Release = 12/02/1994
AMI Date = 7/25/94
Does anyone have a newer BIOS or know which jumper settings are proven to work with the Am5x86-133? The Intel DX4-100 works fine in Write-back mode. The Cyrix 5x86 as least attempts to boot, but stalls in early boot (perhaps related to the VLB SCSI card?).
This motherboard is based on the UMC Um4980 chipset. I realise it is not the most sought after board, but I at least would like to get it running with the Am5x86-160 so that I can compare it with an ASUS board based on the SiS471 chipset.
