Press <Enter> 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
.
