System BIOS Cacheable
Enabling this parameter allows you to change the system BIOS from ROM to

RAM than in ROM. Disabling the parameter prevents the system BIOS from
being cached. The default setting is Enabled .
C000 ~ DC00, 16K Shadow
These parameters are for shadowing expansion cards with ROM. You need to
know the specific addresses that ROMs use to shadow the expansion cards
before you set any of these parameters. If you do not know this information,
enable all the ROM shadow settings. This ensures shadowing of any present
ROMs and reduces the available memory . Select Cached if the data in the
chosen addresses are already copied into RAM.
