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 of 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 make any changes to the default settings.
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.
IRQ Resource Setup
Press <Enter> to enter the sub-menu and the following screen appears:
IRQ
3/4/5/7/9/10/11/14/15
These items specify the bus where the specified IRQ line is used. The settings determines if AMIBIOS
should remove an IRQ from the pool of available IRQs passed to devices that are configurable by the
