Video or Adapter ROM Shadow
ROM shadow is a technique in which BIOS code is copied from
slower ROM to faster RAM. The BIOS is then executed from the
RAM.
Each option allows for a segment of 16KB or 32KB to be shadowed
from ROM to RAM. If one of these options is enabled and there is
BIOS code present in that particular segment, the BIOS is shadowed.
ISA Video ROM Shadow
Video BIOS shadowing may be done in a 32K segment at C000H.
Enabling shadowing can speed up the operation of a machine be-
cause RAM can be accessed more rapidly than ROM and the data
bus is wider to RAM.
