PCI Slot1 IRQ Priority
PCI Slot2 IRQ Priority
PCI Slot3 IRQ Priority
PCI Slot4 IRQ Priority
These options 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, 12, 14,
or 15, 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
IRQ12
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 least one IRQ must be available for PCI and PnP devices. The
settings are PCI/PnP or ISA/EISA.
