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 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.
