System Interrupts; Appendix A: Specification Tables - IBM Aptiva Series Handbook

System interrupts

This table shows the system Interrupt Requests (IRQs) and their functions. You may use this information if you install an
adapter card that requires you to set IRQs. An IRQ function which has a device name in parenthesis may not be available on all
models. In some cases, the device listed uses the IRQ.
