I'm trying to get a VIA VT6421A card bootable on my Biostar MB-8500TTD.
I burned the "Memphis" ROM on an EPROM and stuck it on a PCI Ethernet card. Couldn't reflash the VT6421A's onboard EEPROM, sometimes they are fake.
The ROM will boot on a newer ATX box, but not on the 8500TTD. It has Award BIOS v4.51PG.
