PURPOSE:To simultaneously execute the IPL of a plural slave processors by providing a master processor, plural slave processors and a system bus, and providing plural pieces of IPL control tables. CONSTITUTION:Plural processors 1 to 5 are connected subordinately to the system bus 6. It is assumed that a second and a third processors 3, 4 among them are faulty and IPL processing is being executed simultaneously from the external storage device 13 of the master processor 1 to second, third slave processors 3, 4. Because plural pieces of the IPL control tables only one piece of which was provided in the past are provided in order to execute the IPL of plural slave processors 2 to 5 by using idle time as shown in a waveform diagram, and the competition of IPL control processing is eliminated, and simultaneously, the idle time is used effectively, the IPL of plural slave processors 2 to 5 can be made efficient.
