Thanks for the heads up on that programmer! It arrived and I have successfully flashed the SPAX BIOS chip with the modified SP97-XV BIOS by Jan Steunebrink and the board is now resurrected~
Next up is finding a power supply I can use and hopefully a case for this looong board to fit in.
Then I'll start working out the problems.
Thanks again!
Edit:
So uh, I installed the SP97-XV BIOS and it has a bunch of IRQ and DMA reservations that I can force onto the ISA bus making them unavailable to the built in Crystal PCI sound card. And suddenly, Sound Blaster AWE32 working perfectly~
That wasn't difficult at all~ (other than bricking the board and buying the programmer... it was just more money than I thought the project would cost 😅)
