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

Main power connector (J48)
0E0000h to 0EFFFFh

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.
