Abstract
An apparatus and method for fault resilient booting of a multi-processor system. The apparatus attempts a cold reset of the system, during which each processor performs a built-in self test. The apparatus selects a boot strap processor to perform a warm reset, during which any failed processors are tristated using a flush command. If no boot strap processor is available, the apparatus performs the warm reset and tristates any failed processor including the processor predesignated to be the boot strap processor, and then repeats the attempt to establish the boot strap processor.
