PCIPnP
The PCIPnP menu items allow you to change the advanced settings for PCI/PnP
devices. The menu includes setting IRQ and DMA channel resources for either
PCI/PnP or legacy ISA devices, and setting the memory size block for legacy ISA
devices.
Take caution when changing the settings of the PCI/PnP Configuration menu
items. Incorrect field values can cause the system to malfunction.
Plug And Play O/S [No]
When set to [No], BIOS configures all the devices in the system. When set to
[Yes] and if you install a Plug and Play operating system, the operating system
configures the Plug and Play devices not required for boot.
Configuration options: [No] [Yes]
PCI Latency Timer [64]
Allows you to select the value in units of PCI clocks for the PCI device latency
timer register. Configuration options: [32] [64] [96] [128] [160] [192] [224] [248]
Allocate IRQ to PCI VGA [Yes]
When set to [Yes], BIOS assigns an IRQ to PCI VGA card if the card requests for
an IRQ. When set to [No], BIOS does not assign an IRQ to the PCI VGA card even
if requested. Configuration options: [Yes] [No]
Palette Snooping [Disabled]
When set to [Enabled], the pallete snooping feature informs the PCI devices that
an ISA graphics device is installed in the system so that the latter can function
correctly. Configuration options: [Disabled] [Enabled]
