BIOS Setup

PCI/PNP Resource Management

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.

Clear NVRAM

The NVRAM (Non-volatile Random Access Memory) is where the BIOS stores re- source information for both PNP and non-PNP devices in a bit string format. When the item is set to [Yes], the system will reset NVRAM right after the system is booted up and then set the setting of the item back to [No] automatically.

Plug & Play 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 98, 2000, ME or XP. When set to No, BIOS will initialize all the PnP cards. Select Yes if the operating system is Plug & Play.
