Video BIOS Shadow
It determines whether video BIOS will be copied to RAM, however, it is optional from
chipset design. Video Shadow will increase the video speed.
C8000 - DFFFF Shadow
These categories determine whether other expansion cards ROM BIOS will be copied to
Main memory by 16K byte or 32K byte per/unit and the size depends on chipset. Which
segment should be chose depending on cards ROM BIOS address decoding and chips size.
