BIOS
Offboard PCI IDE Primary IRQ
Offboard PCI IDE Secondary IRQ
These options specify the PCI interrupt used by the primary (or secondary)
IDE channel on the offboard PCI IDE controller. The settings are
Disabled
,
Hardwired
,
INTA
,
INTB
,
INTC
, and
INTD
.
PCI Slot1 & AGP Slot IRQ
PCI Slot2 IRQ
PCI Slot3 & PCI Slot 1, 2 IRQ
PCI Slot4 IRQ
Use these options to specify the IRQ priority for PCI devices installed in
the PCI expansion slots. The settings are
Auto, (IRQ) 3, 4, 5, 7, 9, 10,
11
and
14,
in priority order.
DMA Channel 0
DMA Channel 1
DMA Channel 3
DMA Channel 5
DMA Channel 6
DMA Channel 7
These DMA channels control the data transfers between the I/O devices
and the system memory. The chipset allows the BIOS to choose which
channels to do the job. The settings are
PnP
or
ISA/EISA.
IRQ3
IRQ4
IRQ5
IRQ7
IRQ9
IRQ10
IRQ11
IRQ14
IRQ15
These options specify which bus the specified IRQ line is used on and
allow you to reserve IRQs for legacy ISA adapter cards. If more IRQs
must be removed from the pool, the end user can use these options to
reserve the IRQ by assigning an
ISA/EISA
setting to it. Onboard I/O is
configured by AMIBIOS. All IRQs used by onboard I/O are configured as
PCI/PnP.
IRQ14 and 15 will not be available if the onboard PCI IDE is enabled. If all
IRQs are set to
ISA/EISA
and IRQ14 and 15 are allocated to the onboard PCI
IDE, IRQ 9 will still be available for PCI and PnP devices. This is because at
