PCI Latency Timer (PCI Clocks)

This option specifies the latency of all PCI devices on the PCI Local Bus. The settings are in units equal to PCI clocks.

The Setup screen displays the system option:

PCI Latency Timer (PCI Clocks) 64

Available options are:

 

32

160

PCI VGA Palette Snoop

Palette snooping allows multiple VGA devices operating on different buses to handle data from the processor on each set of palette registers on every video device, e.g. if there are two VGA devices in your system (one PCI and one ISA). Bit 5 of the command register in the PCI device configuration space is the VGA Palette Snoop bit (0 is disabled).

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

The Setup screen displays the system option:

PCI VGA Palette Snoop

Disabled

Two options are available:

•Disabled - Data read and written by the processor is only directed to the PCI VGA device's palette registers.

•Enabled - Data read and written by the processor is directed to both the PCI VGA device's palette registers and the ISA VGA device's palette registers, permitting the palette registers of both devices to be identical.

PCI IDE BusMaster

This option specifies whether the IDE controller on the PCI Local Bus has bus mastering capability. AMIBIOS can perform bus master transfers using scatter/gather DMA on the PCI IDE interface. No special drivers are needed, but the IDE drive must support PCI bus mastering.
