Interrupt Requests
The following paragraphs list the system interrupts (IRQs), parallel interrupts, and serial
interrupts. See Section 4, “System Boards,” for parallel and serial addresses.
System Interrupts
The system has 16 IRQs (IRQ 0 through 15) assigned to different devices (for example, printer,
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 Utility” in this section for information on using the utility to assign or change the
interrupts.
The following table lists the IRQ settings. Assignments 0 through 15 are in order of decreasing
priority.
