Video ROM BIOS Shadow

This field allows you to change the video BIOS location from ROM to RAM. Relocating to RAM enhances system performance because information access is faster than to ROM. Setup default setting is Enabled.

C8000 – CBFFF Shadowto 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.
