Abstract: A method, apparatus, and computer instructions for generating a hardware interrupt to the operating system in response to detecting a presence of the event in the platform. The event is stored in a partition queue associated with a partition firmware in response to the presence of the event. The event is identified in the partition queue, in response to receiving a request to check the hardware interrupt in the partition firmware. The event is processed in response to identifying the event.

Abstract: A method, apparatus and computer instructions for handling exception vectors by firmware. An exception vector is identified to form an identified exception vector when control is passed from an operating system to the firmware. The identified exception vector is saved to form a saved exception vector. The identified exception vector is then replaced with a substitute vector; and the saved exception vector is restored when control is returned to the operating system to form a restored exception vector. At that point, the restored exception vector is again used to perform error and debugging processes.
