Video Cards may not show colors properly. The setting Enabled should correct this
problem. Otherwise leave this on the setup default setting of Disabled.

Video ROM BIOS Shadow
This field allows you to change the video BIOS location from ROM to RAM. Relo-
cating to RAM enhances system performance because information access is faster
than to ROM. Setup default setting is Enabled.
C8000 – CBFFF Shadow to DC000 – DFFFF Shadow
These fields are used for shadowing other expansion card ROMs. If you install
other expansion cards with ROMs on them, you will need to know which addresses
the ROMs use to shadow them specifically. Shadowing a ROM reduces the memory
available between 640KB and 1024KB by the amount used for this purpose. Leave
on default setting of Disabled.
