PNP/PCI Configuration
This section describes configuring the PCI bus system and PnP (Plug &
Play) feature. PCI, or Personal Computer 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 experi-
enced users should make any changes to the default settings.
Clear ESCD
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.
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.
Then you have to turn on the palette “snoop”, permitting the palette
