BIOS Setup 3-13
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.
