Offboard PCI/ISA IDE Card This option specifies if an offboard PCI IDE controller adapter
card is installed in the computer. You must choose ISA if an ISA IDE card is
installed or the PCI expansion slot on the motherboard where the offboard PCI
IDE controller is installed. If an offboard ISA or PCI IDE controller is used, the
onboard IDE controller is automatically disabled. The settings are Auto
(AMIBIOS automatically determines where the offboard PCI IDE controller
adapter card is installed), Absent, ISA, Slot1, SLot2, Slot3, or Slot4. The
Optimal And Fail-Safe default settings are Auto.
In the AMIBIOS for the Intel Triton II ISA chipset, this option forces IRQ14
and IRQ15 to a PCI slot on the PCI local bus. This is necessary to support non-
compliant ISA IDE controller adapter cards.
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 Primary/Secondary This option specifies the IDE controller channels used by the
offboard IDE adapter card. The settings are Disabled, Primary, Secondary, or
Both. There are no Optimal and Fail-Safe default settings.
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.
Serial Port1 IRQ This option specifies the IRQ used for serial port1. The settings are IRQ4 or
Disabled. The Optimal default setting is IRQ4. The Fail-Safe default setting is
Disabled.
