Thanks to everyones help I found the answer. Most HP/Compaq boards of that gen were made by Tyan. The one I referred to above turns out to be the HP version of the "Tyan Thunder K8WE S2895". I hope this might also help someone else looking for detailed specs on these boards. The differences seem to be the BIOS chip, the on-off/reset, LED, and front panel connections. HP has connectors added to the board and there are no pins on the board where the Tyan connections would normally be.
