Abstract:
When a match of a pair of a first configuration register value obtained by a configuration register value obtainment unit and a first configuration register value related to the first configuration register value stored in a storage unit with being related to the first startup control unit, or a match of a pair of a second configuration register value obtained by the configuration register value obtainment unit and a second configuration register value related to the second configuration register value stored in the storage unit with being related to the second startup control unit, is detected, startup processing of an information processing apparatus is continued. Thereby, the startup processing can be completed even when a part of processing units is swapped with a spare processing unit having the same configuration, and the functions of the startup control units can be effectively exploited.
