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.
