IRQ assignments
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 APIC(s).
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 SSU option does not make the interrupt available.
