PCI VGA Palette Snoop
When this option is set to Enabled, multiple VGA devices operating on
different buses can handle data from the CPU on each set of palette registers
on every video device. Bit 5 of the command register in the PCI device
configuration space is the VGA Palette Snoop bit (0 is disabled). For example,
if there are two VGA devices in the computer (one PCI and one ISA) and this
field is set for:
gnitteSnoitpircseD

This option must be set to Enabled if any ISA adapter card installed in the
system requires VGA palette snooping.
Allocate IRQ to PCI VGA
This option allows for allocation of an IRQ address according to the PCI VGA
card. Please note that most PCI VGA cards do not use IRQ - only a select few.
The settings are Yes or No.
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.
OffBoard PCI IDE Card
This option specifies whether or not an offboard PCI IDE controller adapter
card is used in the computer, and where it is installed. If an offboard PCI IDE
controller is used, the motherboard onboard IDE controller is automatically
disabled. The settings are Auto and Slot1
through Slot6. If Auto is selected, AMIBIOS automatically determines the
correct setting (including using the onboard controller if no offboard controller
card is detected). 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.
OffBoard PCI IDE Primary IRQ
This option specifies the PCI interrupt used by the primary IDE channel on the
