• Used MEM base addr and Used MEM Length: The default value is N/A.
The Used MEM base addr (CB00, CC00, D000, D400, D800, DC00)
and Used MEM Length (8K, 16K, 32K, 64K) were to support the some
specific ISA Legacy cards with requested memory space below 1M
address. Now with these two funtions, users canm define where the used
memory address is located and its length of the legacy area that is used
by the legacy device to avoid the memory space conflict. For example, if
users select “D000” for Used MEM base addr” and “16K” for “Used
MEM Length”, that means the address region D000H-D3FFFH is
occupied by ISA legacy cards, and thus BIOS will not assign this region
for PnP/ISA and PCI cards.
