Interrupts

Important

If you disable an IDE controller to free the

interrupt for that controller, you must

physically unplug the IDE cable from the
system board. Simply disabling the drive

by configuring the BIOS option does not

make the interrupt available.

The following table reflects a typical configuration, but you can change these
interrupts. Use this information to determine how to program each interrupt.
