3-16 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. 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
This setting specifies IRQ for PCI devices.PNP/PCI...
