available for loading device drivers, etc.
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 area C0000-C7FFF. The remaining areas
shown on the BIOS Features Setup screen may be occupied by other expan-
sion 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.
