Abstract
A multiprocessor data processing system includes a system management facility which controls the loading of each control store in the respective multiprocessor. The system management facility generates a sequence of commands which puts a processor in load mode, initializes a control store address register, transfers firmware words from a main memory to the control store, resets the load mode, starts a verify operation and checks the result of the verify operation.
