MS-6702E ATX 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. Clear NVRAM The ESCD (Extended System Configuration Data) NVRAM (Non-volatile Random Access Memory) is where the BIOS stores resource information for both PNP and nonPNP devices in a bit string format. When the item is set to [Yes], the system will reset ESCD NVRAM right after the system is booted up and then set the setting of the item back to [No] automatically. Primary Graphics Adaptor This setting specifies which VGA card is your primary graphics adapter. Setting options: [PCI], and [AGP]. PCI Slot1 IRQ, PCI Slot2/5 IRQ, PCI Slot3 IRQ, PCI Slot4 IRQ These items specify the IRQ line for each PCI slot. Setting options: [3], [4], [5], [7], [9], [10], [11], and [Auto]. Selecting [Auto] allows BIOS to automatically determine the IRQ line for each PCI slot. 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. Settings range from [32] to [248] at a 32 increment. 3-14
