American Megatrends MAN-772 manual Peripheral Setup, Primary Prefetch, IDE Secondary IRQ options

Peripheral Setup

Choose the Peripheral Setup icon from the WINBIOS Setup screen to display the Peripheral Setup options, described below.

Onboard Floppy Controller Set this option to Enabled to enable the floppy drive controller on the motherboard. The settings are Enabled or Disabled. The Optimal and Fail-Safe default settings are Enabled.

Onboard Primary/Secondary IDE This option specifies the IDE channels on the onboard IDE controller that will be used. The settings are Disabled, Primary, Secondary, or Both. The Optimal and Fail-Safe default settings are Disabled.

Onboard IDE Bus Master Set this option to Enabled to specify that the IDE controller on the PCI local bus includes a bus mastering capability. The settings are Enabled or Disabled. The Optimal and Fail-Safe default settings are Disabled.

Primary Prefetch

Secondary Prefetch These options specify the IDE channel or channel where prefetch is enabled. The settings are Disabled, Master, Slave, or Both. There are no default settings.

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.

Onboard 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.
