For best results, disable both of these options.

SeaBIOS runs all the option roms directly.

Coreboot is still having issues running the vga rom.

Not being able to find the coreboot table is an odd error - it needs
to be fixed as it results in incorrect memory sizing.

Here you can see SeaBIOS runs three option roms.
