VGA Palette
Snoop Bit Action
Disabled Data read and written by the CPU is only directed to the
PCI VGA device's palette registers.
Enabled Data read and written by the CPU is directed to the both
the PCI VGA device's palette registers and the ISA VGA
device palette registers, permitting the palette registers of
both devices to be identical.
This option must be set to Enabled if any ISA adapter card installed in
the system requires VGA palette snooping. The Optimal and Fail-Safe
default settings are Disabled.
4.7.4 PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI bus has bus
mastering capability. The settings are Disabled or Enabled . The Optimal and Fail-Safe
default settings are Disabled.
4.7.5 Off Board PCI IDE Card
This option specifies if an off board PCI IDE controller adapter card is used in the
computer. You must also specify the PCI expansion slot on the motherboard where the
off board PCI IDE controller card is installed. If an off board PCI IDE controller is used,
the motherboard onboard IDE controller is automatically disabled. The settings are
Disabled, Auto, Slot1, Slot2, Slot3, Slot4, Slot5, or Slot6. If Auto is selected, AMIBIOS
automatically determines the correct setting. The Optimal and Fail-Safe default settings
are
Auto. This option forces IRQ 14 and 15 to a PCI slot on the PCI local bus. This is
necessary to support non-compliant PCI IDE adapter cards.
4.7.6 Off Board PCI IDE Primary IRQ
This option specifies the PCI interrupt used by the primary IDE channel on the off
board PCI IDE controller. The settings are
Disabled, Hardwired, INTA, INTB, INTC , or
INTD . The default setting is Disabled.
4.7.7 Off Board PCI IDE Secondary IRQ
This option specifies the PCI interrupt used by the secondary IDE channel on the off
board PCI IDE controller. The settings are
Disabled, Hardwired, INTA, INTB, INTC , or
INTD . The default setting is Disabled.
4.7.8 Assign IRQ to PCI VGA Card
Assign the IRQ# for VGA card.
