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
Yes
, 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
®
95 or 98. When set to
No
, BIOS will initialize all the PnP cards.
So, select
Yes
if the operating system is Plug & Play aware.
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.
