Offboard PCI IDE Card
This option specifies if an offboard 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
the offboard PCI IDE controller adaper card is installed), Slot1, Slot2, Slot3 or
Slot4. The Optimal and Fail-Safe settings are Auto.
If an offboard 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.
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 or INTD. The Optimal and Fail-Safe
default settings are Disabled.
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
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.
