OffBoard PCI IDE Primary IRQ/Secondary IRQ
These options specify the PCI interrupts used by the primary and secondary IDE channels on the
off-board PCI IDE controller.
If the OffBoard PCI IDE Card option described above is set to Auto, these options are not avail-
able.
The Setup screen displays the system options:
OffBoard PCI IDE Primary IRQ
Disabled
OffBoard PCI IDE Secondary IRQ
Disabled
Available options are:
Disabled
INTA
INTB
INTC
INTD
Hardwired
DMA Channels 0, 1, 3, 5, 6 and 7
The Setup screen displays the system option:
DMA Channel#
PnP
where # is the DMA Channel number.
Available options are:
PnP
ISA/EISA
IRQ5/IRQ9/IRQ10/IRQ11/IRQ15
These options indicate whether or not the specified interrupt request (IRQ) is available for use by
the system for PCI/Plug and Play features or is reserved for use by option cards on the ISA Bus.
This allows you to specify IRQs for use by legacy ISA adapter cards. The IRQ setup options
indicate whether AMIBIOS should remove an IRQ from the pool of available IRQs passed to BIOS
configurable devices. If more IRQs must be removed from the pool, you can set the IRQ option to
ISA/EISA. On-board I/O is configurable by AMIBIOS; the IRQs used by on-board I/O are config-
ured as PCI/PnP.
