4.4.4 Shadow Configuration

Video ROM BIOS Shadow [Enabled]

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

C8000-DFFFF Shadow [Disabled]

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 640K and 1024K by the
amount used for this purpose. Configuration options: [Disabled] [Enabled]
