A method for supporting multiple distributed interrupt controllers, designated as bus agents, in a symmetric multiprocessing system, which method 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, which computer 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.
