PNP/PCI Configurations

This section describes configuring the PCI bus system and PnP (Plug & Play)

feature. PCI, or Peripheral Component Interconnect, is a system which allows

I/O devices to operate at speeds nearing the speed the CPU itself uses when

communicating with its special components. This section covers some very

technical items and it is strongly recommended that only experienced users

should make any changes to the default settings.

Plug and Play Aware O/S

When set to Ye s, BIOS will only initialize the PnP cards used for booting (VGA,

IDE, SCSI). The rest of the cards will be initialized by the PnP operating system

like Windows

98, 2000 or ME. When set to No, BIOS will initialize all the PnP

cards. Select Yes if the operating system is Plug & Play.

Clear NVRAM

The ESCD (Extended System Configuration Data) NVRAM (Non-volatile Ran-

dom Access Memory) is where the BIOS stores resource information for both

PNP and non-PNP devices in a bit string format. When the item is set to Yes,

the system will reset ESCD NVRAM right after the system is booted up and

then set the setting of the item back to No automatically.
