reduces the amount of high memory (640KB to 1MB) available for

Video BIOS shadows into memory area C0000-CBFFF. 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.
