4.4.19 Video BIOS Shadow
This field allows you to change the video BIOS location from ROM to RAM. Relocating to
RAM enhances system performance, as information access is faster than the ROM.
4.4.20 C8000-CBFFF to DC000-DFFFF
These fields are used for shadowing other expansion card ROMs. If you install other
expansion cards with ROMs on them, you will need to know which addresses the ROMs use
to shadow them specifically. Shadowing a ROM reduces the memory available between
640KB and 102KB by the amount used for this purpose.
