Shadow
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, for example, 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 impoves 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 sect ion of memory separately. Many
system designers hardwire shadowing of the system BIOS and
eliminate a System BIOS Shadow option.
Video BIOS sh adows 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.
