A system for controlling initialization and self-test operations in a multiprocessor system (100) facilitates the use of central processing units (120, 132, 160) based around differing microprocessor types. More specifically, the present invention involves storing configuration information, initialization self-test code, and boot code specific to each processor, memory module, or I/O circuit board in non-executable form in a non-volatile memory (123,129, 133, 161) on the respective circuit board, and storing the executable portion of the boot code needed by the initial boot processor in a centrally accessible non-volatile memory (152). Moreover, the present invention provides a system to automatically transfer default system initialization operations from a de- fault processor to a first alternative processor if the default processor fails, and to automatically transfer initialization operations to a second alternative processor if the first alternative processor fails, and so forth depending upon how many alternative proces- sors are installed in the multiprocessor system (100).
