IRQ3/IRQ4/IRQ5/RQ7/IRQ9/IRQ10/IRQ11/IRQ14/IRQ15
These options specify the bus that the specified IRQ line is used on.
These options allow you to reserve IRQs for legacy ISA adapter cards.
These options determine if AMI
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 pool, the end user can use
these options to reserve the IRQ by assigning an ISA/EISA setting to it.
Onboard I/O is configured by AMI
are configured as PCI/PnP. If all IRQs are set to ISA/EISA and IRQ14 and 15
are allocated to the onboard PCI IDE, IRQ9 will still be available for PCI and
PnP devices, because at least one IRQ must be available for PCI and PnP
devices. The settings are ISA/EISA or PCI/PnP. The Optimal and Fail-Safe
default settings are IRQ3 through 7 are ISA/EISA. The Optimal and Fail-Safe
default settings PCI/PnP.
