4. BIOS SETUP

PCI 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]

Reserved MEM Block BASE [No/ICU]

This field allows you to set the base address and block size of an onboard

legacy ISA device that uses any memory segment within the C800 and DFFF

address range. If you have such a device and you are not using an ICU to

specify its address range, select a base address from the six available op-

tions; the Reserved MEM Block SIZE field will then appear for selecting

the block size. If you have more than one legacy ISA device onboard that

requires the use of this address range, you can increase the block size to 8K,

16K, 32K, or 64K. If you are using an ICU to accomplish this task, leave

Reserved MEM Block BASE to its default setting of [No/ICU]. Configu-

ration options: [No/ICU] [C800] [CC00] [D000] [D400] [D800] [DC00]
