PCI IRQ Assignment
By default, an IRQ is automatically assigned to the PCI devices that
are installed in the PCI slots. If a PCI device has not been assigned
an IRQ, you must manually assign an IRQ for the device. During
system boot-up, you will see NA for the device that does not
have an IRQ assigned.
