PCI Latency Timer (PCI Clocks)
This option specifies the latency timings (in PCI clocks) for PCI
devices installed in the PCI expansion slots. The settings are 32, 64, 96,
128, 160, 192, 224, or 248.
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:

This option must be set to Enabled if any ISA adapter card installed in
the system requires VGA palette snooping.
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.
