That's a PC-Chips M537 (note: not M537DMA33 aka M537+). Inspect the south bridge chip, it must be a VIA 586A or B to support USB at all.

Round that time, there were pre-1.0 USB chips out from all chipset manufacturers, shipped in anticipation of the 1.0 standard not changing anything relevant. It did however, rendering the pre-1.0 USB controllers useless. Later BIOSes for the boards affected then went to hide their USB ports.

OK, 586B has working USB. First of all, inspect the hardware on whether you got a VXpro or a VXpro+ chipset there - to find whether your board is a 537 or a 537DMA33.

Then visit go.to/ajz and click yourself through to the 53x folder to access all the collected resources for this board, including diagrams and later BIOSes.

VXPro = 537 , right?

Yes ... although I'm a bit surprised to find a 586B on the older board. Look in the corner near the keyboard connector, there should be a revision number Vx.x there. What is it?

V5.1A

Ah, so it's the just-short-of-having-the-new-chipset revision. IIRC, v5.2 was the first one to use the VIA VPX north bridge, not the VP-1 (and henceforth using the VXpro+ alias name).
