Hi,

I removed the VGA BIOS from my MS-6159 ROM, but it doesn’t launch the external VGA BIOS.
I soldered two BIOS chips piggy-back and made them selectable so I can experiment with the BIOS.

cbrom bios.bin /vga release — this removed the VGA BIOS.

However, my Matrox card never initializes unless I add the Matrox VGA BIOS directly to the main BIOS ROM.
What do I need to modify in order to get my BIOS to launch the ROM on the PCI card?

Thanks,
Matthias
