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]
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]
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 DC00 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 to use this
address range, you can increase the block size to either 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]
