BIOS Setup [PCI/AGP] [PCI/Int-VGA] The system initializes the installed PCI VGA card first. If a PCI VGA card is not available, it will initialize the AGP card. The system initializes the installed PCI VGA card first. If a PCI VGA card is not available, it will initialize the onboard VGA device. PCI IDE BusMaster Set this option to [Enabled] to specify that the IDE controller on the PCI local bus has bus mastering capability. Setting options: [Disabled], [Enabled]. PCI Slot1/Slot4 IRQ Priority, PCI Slot2 IRQ Priority, PCI Slot3 IRQ Priority, PCI Slot5 IRQ Priority These items specify the IRQ line for each PCI slot. Setting options: [3], [4], [5], [7], [9], [10], [11], [Auto]. Selecting [Auto] allows BIOS to automatically determine the IRQ line for each PCI slot. Set IRQs to PCI or ISA Press to enter the sub-menu and the following screen appears: IRQ 3/4/5/7/9/10/11/14/15 These items specify the bus where the specified IRQ line is used. The settings determine if AMIBIOS should remove an IRQ from the pool of available IRQs passed to devices that are configurable by the system BIOS. The available IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must be removed from the IRQ pool, the end user can use these settings to reserve the IRQ by assigning an [ISA/EISA] setting to it. Onboard I/O is configured by AMIBIOS. All IRQs used by onboard I/O are configured as PCI/PnP. If all IRQs are set to [ISA/EISA], and IRQ 14/15 are allocated to the onboard PCI IDE, IRQ 9 will still be available for PCI and PnP devices. Available settings: [ISA/EISA] and [PCI/PnP]. Set DMAs to PnP or ISA Press to enter the sub-menu and the following screen appears: 3-17
