If your computer adheres to the Intel MultiProcessor Specification version 1.4, Peripheral Component Interconnect (PCI) devices may display interrupt request (IRQ) numbers above 15.

NOTE: the IRQs for the el59x and aic78xx devices.

NOTE: Press Hardware Resources and IRQ information.

This condition is normal and results from the way that the BIOS and HAL interacts with the computer's Asynchronous Processor Interrupt Controller (APIC).
