In the end I tried both of the Mr-bios files to test them, V097B5NA.BIN and V097B5NA.BIO. They have different sha-1 hash values and after flashing each one and testing I can't make out any differences. All bios options and version # appear identical.
A big problem now though, all PCI cards I have (S3 TRIO, Promise TX2 IDE controller, YMF 724) don't work. The Intel Advanced Morrison motherboard (430fx chipset) uses a LPX form factor and a riser card for ISA/PCI. All my ISA cards still work but if I insert any PCI card in the riser the computer will freeze when loading DOS. It completes POST but when loading DOS the screen stays black or is black with a blinking underscore in the top left corner. There is a PCI menu section in Mr-bios where you can assign SLOT# (1-20), INT A,B,C,D and low or high level IRQ trigger. I have tried most combinations without success. The riser that came with this motherboard has 2 PCI slots and 3 ISA.
Has anyone in here flashed an Intel-Morrison motherboard to Mr-bios and got it working with PCI cards.
