    Abstract: A method for supporting multiple distributed interrupt controllers, designated as bus agents, in a symmetric multiprocessing system, includes the steps of assigning a unique identification number to each bus agent, receiving bus requests from the bus agents over four data lines in groups of four, and granting bus ownership to a selected one of the requesting bus agents. Similarly, a computer system that supports multiple distributed interrupt controllers, designated as bus agents, in a symmetric multiprocessing system, includes structure for assigning a unique identification number to each bus agent, four data lines for receiving bus requests from the bus agents in groups of four, and structure for granting bus ownership to a selected one of the requesting bus agents.

    Abstract: A hot spare boot circuit that automatically switches from a non-operational CPU to an operational CPU for powering up the computer system. In the multiprocessor computer system, a first CPU is designated to perform power on operations. If the first CPU fails, which is determined when a dead man counter in the hot spare boot circuit times out, the hot spare circuit ensures that the first CPU is in a disabled state. Next, the hot spare boot circuit identifies an operational second CPU, reinitializing certain ID information as necessary such that the second CPU can properly perform power on operations. The hot spare boot then awakens the second CPU, using a startup interprocessor interrupt in one embodiment, or simply negating the hard reset of the second CPU in a second embodiment. The second CPU then proceeds to perform the power on functions.
