ABSTRACT:
A multiprocessor system containing a plurality of processor boards each having at least one processor, a CPU (central processing unit) which has malfunctioned when the multiprocessor system boots up can be firmly isolated from a system bus. In this multiprocessor system, each of the plural processor boards includes a nonvolatile memory for storing therein an initial diagnosis result of each processor on this processor board. When a system boots up, a master processor in the respective processor boards is selected based upon the initial diagnosis result stored in the nonvolatile memory, and furthermore, a master processor for the entire system is selected from these selected master processors.
