PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI local bus has
bus mastering capability. The settings are Disabled or Enabled. The Optimal and Fail-
Safe default setting is “Disabled”.
•
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, and 11, in priority order. The
Optimal and Fail-Safe default settings are Auto.
DMA Channel 0 to DMA Channel 7
This option can be used to reserve a DMA channel for use by legacy ISA adapter
cards. The settings are Disabled, DMA ChI, DMA Ch 3 DMA Ch 5, DMA Ch 6, or DMA
Ch 7. The Optimal and Fail-Safe default settings are PnP.
IRQ3 to IRQ15
These options specify the bus that the named interrupt request lines (IRQs) are used
on. These options allow you to specify IRQs for use by legacy ISA adapter cards.
These options determine if AMIBlOS should remove an IRQ from the pool of available
IRQs passed to BIOS configurable devices. The available IRQ pool is determined by
readling the ESCD NVRAM. If more IRQs must be removed from the pool, the end user
can use these PCI/PnP Setup options to remove the IRQ by assigning the option to the
ISA/ElSA setting. Onboard I/O is configurable by AMIBlOS. The IRQs used by onboard
I/O are configured as PCi/PnP.
The settings are PCI/PnP or ISA/EISA. The Optimal and Fail-Safe default settings are
“PCI/PnP”.
