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 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.
