System Interrupts - IBM Aptiva Handbook

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 that has a device name in parenthesis might not be available on all models.
In some cases, the device listed uses the IRQ.
