Configuring shadow memory
Select the Memory Shadow option to enable video BIOS
shadowing or configure specific option ROM shadow blocks.
Note
Shadowing for the system BIOS is always enabled. For the best
system performance, always set the Video Shadow option to
Enabled
(the default setting).
Your computer can access RAM faster than ROM. The options
on this screen allow your system to copy the contents of its video
ROM and any optional ROMs into RAM. When you use
shadowing, your system can perform certain operations faster,
providing a significant increase in performance.
Note
Some option ROMs cannot be shadowed using the Shadow
Memory Region options; see the documentation that came with
your optional equipment for information on shadowing the
option’s BIOS ROM.
