Abstract

A system and method to determine a healthy group of processors and associated firmware for booting a system after a resetting event is disclosed. Redundant copies of processor specific firmware are examined for validity. Processors determine their own health status, and one processor determines a group of processors with the best available health status. Inter-processor interrupt messages provide the communication mechanism to allow an algorithm to determine a group of processors to continue booting the system.
