4.4.4 Shadow Configuration

Video ROM BIOS Shadow [Enabled]

When enabled, this field allows you to change the video BIOS location
from ROM to RAM. Relocating the video BIOS to RAM enhances system
performance because information access is faster than in ROM.
Configuration options: [Disabled] [Enabled]

C8000-DFFFF Shadow [Disabled]

These fields are used for shadowing other expansion card ROMs. If you
install any expansion card with a built-in ROM, you need to know which
addresses the ROM uses to specifically shadow them. Shadowing a ROM
reduces the memory available between 640K and 1024K by the amount
used for this purpose. Configuration options: [Disabled] [Enabled]
