Software that resides in a read only memory (ROM) chip on a device is called firmware.
The Award BIOS permits shadowing of firmware such as the system BIOS, video BIOS,
and similar operating instructions that come with some expansion peripherals such as a
SCSI adaptor. Shadowing copies firmware from ROM into system RAM, where the CPU
can read it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be
read by the system through the 8-bit X-bus. Shadowing improves the performance of
the system BIOS and similar ROM firmware for expansion peripherals. But it also
reduces the amount of high memory (640 KB to 1 MB) 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 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.
