BIOS Setup

Primary Graphic’s Adapter

This setting specifies which graphics card is your primary graphics adapter.

PCI Latency Timer

This item controls how long each PCI device can hold the bus before another takes

over. When 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.

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.
