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 graphics card is your primary graphics adapter. Settings
are:
[PCIE1 -> PCIE2 -> PCI] The system initializes the PCI Express graphics card
that installed in PCIE x 16 first slot first.
[PCIE2 -> PCIE1 ->PCI] The system initializes the PCI Express graphics card
that installed in PCIE x 16 second slot first.
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.
PCI Slot 1/2 IRQ
These items specify the IRQ line for each PCI slot.
