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.
Primary Graphics Adapter
This setting specifies which VGA card is your primary graphics adapter.
PCI Latency Timer
This feature controls how long each PCI device can hold the bus before another
takes over. The larger the value, the longer the PCI device can retain control of the
bus. As each access to the bus comes with an initial delay before any transaction
can be made, low values for the PCI Latency Timer will reduce the effective PCI
bandwidth while higher values improve it. Key in a DEC number between [0] and
[255].
