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 NVRAM
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 wil 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
When set to [Enabled], multiple VGA devices operating on different buses can handle
data from the CPU on each set of palette registers on every video device. Bit 5 of the
command register in the PCI device configuration space is the VGA Palette Snoop bit (0
is disabled). For example, if there are two VGA devices in the computer (one PCI and
one ISA) and the:
