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 a memory segment within the C800 and DFFF address range.
If you have such a card and you are not using ICU to specify its address
range, select a base address from the six available options.
When you select an option other than [No/ICU], the ISA MEM Block SIZE
field appears for selecting the block size. If there is more than one legacy
ISA card in the 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 ICU to
accomplish this task, leave ISA MEM Block BASE to its default setting
[No/ICU]. Configuration options: [No/ICU] [C800] [CC00] [D000] [D400]
[D800] [DC00]
Video ROM BIOS Shadow [Enabled]
When enabled, this field allows you to change the video BIOS location
from ROM to RAM. Relocating the video BIOS to RAM enhances system
performance because information access is faster than in ROM.
Configuration options: [Disabled] [Enabled]
C8000-DFFFF Shadow [Disabled]
These fields are used for shadowing other expansion card ROMs. If you
install any expansion card with a built-in ROM, you need to know which
addresses the ROM uses to specifically shadow them. Shadowing a ROM
reduces the memory available between 640K and 1024K by the amount
used for this purpose. Configuration options: [Disabled] [Enabled]
