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 communi-
cating 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 ESCD
The ESCD (Extended System Configuration Data) NVRAM (Non-volatile Random Ac-
cess 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.
Primary Graphics Adapter
This setting specifies which VGA card is your primary graphics adapter. Setting
options are:
[Auto] The system will automatic detect the current graphic card.
[PCI Mode] The system initializes the installed PCI VGA card first.
