MS-7511 Mainboard 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. 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 1/2/3 IRQ This setting specifies IRQ for PCI devices. IRQ Resources Setup Press and you will enter the sub-menu of the items. IRQ Resources list IRQ 3/4/5/7/9/10/11/12/14/15 for users to set each IRQ a type depending on the type of device using the IRQ. Settings are: PCI Device For Plug & Play compatible devices designed for PCI bus architecture. Reserved The IRQ will be reserved for further request. 3-16
