IRQ Settings

The hardware interrupts (IRQs) are automatically assigned for each PCI slot and embedded device in the
NetServer. The automatic IRQ assignments are made by the BIOS during the boot process. Additional IRQs
are required beyond the standard set of 15 since some accessory boards, like multi-port adapter boards,
may require more than one IRQ per slot. A special hardware feature (APIC) eliminates interrupt conflicts by
providing an expanded set of IRQs with up to four dedicated interrupts for each PCI slot.
