PCI PnP
The PCI PnP 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
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]

timer register.

if requested.
