4. BIOS SETUP PCI Configuration
Video ROM BIOS Shadow [Enabled]
This field allows you to change the video BIOS location from ROM to RAM. Relocat-
ing 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 avail-
able 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]
