The following table reflects a typical configuration, but you can change these interrupts. Use this information to determine how to program each interrupt. The actual interrupt map is defined using configuration registers in the I/O controller. I/O Redirection Registers in the I/O APIC are provided for each interrupt signal. The signals define hardware interrupt signal characteristics for APIC messages sent to local APICs.
If you disable an IDE controller to free the interrupt for that controller, you must physically unplug the IDE cable from the motherboard. Simply disabling the drive by configuring the SSU option does not make the interrupt available.
