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