Asus P/I-AP55T - Manual (Page 56)

P/I-AP55T User's Manual
If you have a legacy ISA card that uses any memory segment in
the C800h to DCOOh address range and you have not used an ICU to
specify the range it uses, you should set the base address and block
size by using the "ISA MEM Block BASE" line. When you select a
base address from the six options, the "ISA MEM Block SIZE" line
will appear and you can select a block size from the four options. If
you use an ICU to accomplish the same thing, leave "ISA MEM
Block BASE" on the default "No/ICU" setting. If you have more than
one legacy ISA card that needs to use this address range, you can
increase the block size as necessary.
