System Interrupts

The system has 16 IRQs (IRQ 0 through 15) assigned to different devices (for
example, printer, modem, keyboard, mouse). Initial IRQ settings are assigned at
the factory, with settings dependent on the installed device(s). Several IRQs are
unassigned for the installation of add-on devices. See "BIOS Setup" in this
section for information on using the BIOS Setup utility to assign or change the
interrupts.
The following table lists the IRQ settings. Note that assignments 0 through 15
