4. BIOS SETUP

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]

D0000-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]

ISA MEM Block BASE [No/ICU]

This field allows you to set the base address and block size of a legacy ISA

card that uses any memory segment within the C800 and DFFF address

range. If you have such a card and you are not using an ICU to specify its

address range, select a base address from the six available options; the ISA

MEM Block SIZE field will then appear for selecting the block size. If you

have more than one legacy ISA card in your system 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 ISA MEM Block

BASE to its default setting of [No/ICU]. Configuration options: [No/ICU]

[C800] [CC00] [D000] [D400] [D800] [DC00]
