3-6. PnP/PCI Configurations

Plug and Play Aware O/S:

This item allows you to use a PnP operating system to configure the PCI bus slots instead of the BIOS. When set to [Yes], the interrupts may be reassigned by the BIOS. If you installed a non-PnP OS, or if you want to prevent re assigning of interrupt settings, keep the default setting [No].

PCI Latency Timer (PCI Clocks):

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.

Primary Graphics Adapter:

This item selects whether to initialize the AGP or PCI first when the system boots.

•[AGP]: When the system boots, it will first initialize the AGP.•[PCI]: When the system boots, it will first initialize PCI.Allocate IRQ to VGA:This item assigns an IRQ for the VGA card installed.•[Yes]: Automatically assign an IRQ for the VGA card installed.

•[No]: The IRQ that was previously occupied by the VGA card will be available for new device.
