PCI/Plug and Play Setup
Plug and Play Aware O/S
Set this option to Yes to inform the BIOS that the operating system can handle plug and Play
(PnP) devices. The settings are No and Yes. The Optimal default setting is No.
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, and 248. The Optimal
default setting is 64.
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:
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 default setting is Disabled.
Allocate IRQ to PCI VGA
The Optimal default setting is No.
