IRQ3
IRQ4
IRQ5
IRQ7
IRQ9
IRQ10
IRQ11
IRQ12
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 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 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 AMIBIOS. All
IRQs used by onboard I/O are configured as PCI/PnP.

IRQ12 only appears if the Mouse Support option in Advanced Setup is
set to Disabled.

IRQ14 and 15 will not be available if the onboard PIIX3 PCI IDE is
enabled. 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 or PCI/PnP. The Optimal and Fail–Safe default
settings are PCI/PnP.
