OffBoard PCI IDE Card
This option specifies if an off board PCI IDE controller adapter card is
installed in the computer. You must specify the PCI expansion slot on the
mainboard where the offboard PCI IDE controller is installed. If an offboard
PCI IDE controller is used, the onboard IDE controller is automatically
disabled. The settings are Auto(AMI
®
BIOS automatically determines where
the offboard PCI IDE controller adaper card is installed), Slot1, Slot2, Slot3 or
Slot4. The Optimal and Fail-Safe settings are Auto.
If an off board PCI IDE controller adapter card is installed in the
computer, you must also set the Offboard PCI IDE Primary IRQ and Offboard
PCI IDE Secondary IRQ options.
DMA Channel 0/1/3/5/6/7
These options specify the bus that the specified DMA channel is
used. These options allow you to reserve DMAs for legacy ISA adapter
cards.
These options determine if AMI
®
BIOS should remove a DMA from
the available DMAs passed to devices that are configurable by the system
BIOS. The available DMA pool is determined by reading the ESCD
NVRAM. If more DMAs must be removed from the pool, the end user can
use these options to reserve the DMA by assigning an ISA/EISA setting to
it.
IRQ3/IRQ4/IRQ5/RQ7/IRQ9/IRQ10/IRQ11/IRQ14/IRQ15
These options specify the bus that the specified IRQ line is used on.
These options allow you to reserve IRQs for legacy ISA adapter cards.
These options determine if AMI
®
BIOS should remove an IRQ from
the pool of available IRQs passed to devices that are configurable by the
system BIOS. The available IRQ pool is determined by reading the ESCD
NVRAM. 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 AMI

BIOS. All IRQs used by onboard I/O
