Enable shadowing into each section of memory separately. Many
system designers hardwire shadowing of the system BIOS and
eliminate a System BIOS Shadow option.
Video BIOS shadows into memory are C0000-C7FFF. The remaining
areas shown on the BIOS Features Setup screen may be occupied
by other expansion card firmware. If an expansion peripheral in
your system contains ROM-based firmware, you need to know the
address range the ROM occupies to shadow it into the correct area
of RAM.
