Advanced PCI/PnP Settings
• Clear NVRAM – [No] or [Yes]
This field is used to clear NVRAM during system boot.
• Plug & Play O/S – [No] or [Yes]
∗ If [No] is selected, the BIOS is allowed to configure all the devices in the system.
∗ If [Yes] is selected, the Operating System (OS) is allowed to change the interrupt, I/O, and
DMA settings for the devices in the system. This is only used by Plug & Play capable OSs.
• PCI Latency timer – [32], [64], [96], [128], [160], [192], [224], or [248]
This feature sets the latency of all PCI devices on the PCI bus. The various settings allow the
PCI Latency timer to be adjusted to the number of clock cycles specified. The default setting
[64] adjust the PCI Latency timer to 64 PCI clock cycles.
• Allocate IRQ to PCI VGA – [Yes] or [No]
This field allows or restricts the system from giving the VGA adapter card an interrupt address.
∗ If [Yes] is selected, the BIOS is allowed to allocate an IRQ to any VGA adapter card that uses
the PCI local bus.
• Palette Snooping – [Disabled] or [Enabled]
∗ If [Disabled] is selected, the BIOS prevents the VGA card from using Palette Snooping. This
should not be changed unless the VGA card manufacturer requires this feature to be Enabled.
