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 Graphic's Adapter
This setting specifies which graphic card is your primary graphics adapter. Setting
options are:
[PEG] The system initializes the installed PEG card first. If an PEG card is
not available, it will initialize the PCI VGA card.
[PCI] The system initializes the installed PCI VGA card first. If a PCI VGA
card is not available, it will initialize the PEG card.
PCI Latency Timer
This item controls how long each PCI device can hold the bus before another takes
over. W hen set to higher values, every PCI device can conduct transactions for a
longer time and thus improve the effective PCI bandwidth. For better PCI performance,
you should set the item to higher values. Setting options: [32], [64], [96], [128], [160],
[192], [224], [248].
