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 operat-
ing system like Windows ® 98, 2000 or ME. When set to No, BIOS will initial-
ize all the PnP cards. Select Yes if the operating system is Plug & Play.
Clear NVRAM
The ESCD (Extended System Configuration Data) NVRAM (Non-volatile
Random 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.
