ISA Shared Memory Base Address
Sets the base address for the ISA Shared Memory. The options are C8000h,
CC000h, D0000h, D4000h, D8000h, and DC000h. This setting could affect the
ISA Shared Memory Size item. The value entered in the ISA Shared Memory
Size item cannot extend to the E0000h address. For example, if a size of 64K
was selected, options D4000h, D8000h, and DC000h will not be available.
IRQ 3, 4, 5, 7, 9, 10, 11, 12, 14, 15
Sets the status of the IRQ. The options are Available and Used By ISA Card. The
PCI auto-configuration code looks here to see if these interrupts are available for use
by a PCI add-in board. If an interrupt is available, the PCI auto-configuration code
can assign the interrupt to be used by the system. If your system contains an ISA
agent that uses one of these interrupts, select Used By ISA Card for that interrupt.
NOTE
Some of the IRQ's may not be available in this option, depending
on the setting chosen for the COM1, COM2 and parallel ports in
the Peripheral Configuration Subscreen.
