PCI IDE IRQ Map to
This field is used to select the PCI IDE IRQ mapping or PC AT(ISA) interrupt. If the
system does not require one or both of the PCI IDE connectors on the system board,
select a value based on the type (PCI or ISA) of IDE interfaces (one or more) installed
on the system. The standard ISA interrupts for the IDE channels are IRQ14 for the
primary IDE and IRQ15 for the secondary IDE.
Selection options: PCI-SLOT1, PCI- SLOT 2, PCI- SLOT 3, PCI- SLOT 4, ISA, PCI-
Auto
Primary/Secondary IDE INT#
A maximum of four interrupts (INTA#, INTB#, INTC#, and INTD#) can be active for
each PCI peripheral connection. By default, INTA# is assigned to a PCI connection.
Assigning INTB# is meaningless unless the peripheral device requires two interrupt
services. As the chipset’s PCI IDE interface has two channels, it requires two
interrupt services. The default settings for the primary and secondary IDE INT#
fields specify values appropriate for two PCI IDE channels and a lower interrupt is
assigned to the primary PCI IDE channel than for the secondary PCI IDE channel.
Used MEM base addr
Selects the base address of the memory area for peripheral devices that require access
to high memory.
Selection options: C800, CC00, D000, D400, D800, DC00, N/A
Used MEM Length
Specifies the size of the memory area specified by the previous field. The memory
length field only appears if a base address is specified.
Selection options: 8K, 16K, 32K, 64K
