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.
Clear ESCD
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.
Primary Graphics Adapter
This item specifies which VGA card is your primary graphics adapter. Settings:
PCI, AGP.
PCI VGA Palette Snoop
PCI VGA palette is the set of colors currently used by the video device.
Some special VGA cards may not show colors correctly and need to look
into the video device’s VGA palette to determine what colors are in use.
