These options specify the bus that the named interrupt request
lines (IRQs) are used on. These options allow you to specify IRQs
for use by legacy ISA adapter cards.
These options determine if AMIBIOS should remove an IRQ from
the pool of available IRQs passed to BIOS configurable devices.
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 PCI/PnP Setup options to remove the IRQ by
assigning the option to the ISA/EISA setting. Onboard I/O is
configurable by AMIBIOS. The IRQs used by onboard I/O are
configured as PCI/PnP.
The settings are PCI/PnP or ISA/EISA.
