AMI BIOS Setup PCI IDE Bus Master Set this option to Enabled to specify that the IDE controller on the PCI local bus has bus mastering capability. Options are Disabled and Enabled. PCI Slot 1/5 IRQ, PCI Slot 2 IRQ, PCI Slot 3 IRQ, PCI Slot 4 IRQ This item specifies the IRQ line for each PCI slot. Settings: 3, 4, 5, 7, 9, 10, 11 and 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. 3-19
