4. BIOS SETUP
PCI/PNP UMB Resource Exclusion
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 device onboard that re-
quires 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]
