<P>PROBLEM TO BE SOLVED: To provide a computer system capable of performing a normal system recovery by preventing data from being rewritten due to the initialization processing of a system by a watch dog timer or interrupt processing due to an interrupt signal in a device for performing a retry operation by returning to a check point. <P>SOLUTION: The watch dog timer is initialized as a first process of processes to restore the data of a main memory until a check point time (S105). Alternatively, an interrupt controller is set to an interruption inhibition state as a first process of processes to restore the data of the main memory until the check point time, and the data of the main memory and the data of the register of the CPU are restored until the check point time, and the interrupt inhibition state of the interrupt controller is released. <P>COPYRIGHT: (C)2009,JPO&INPIT |
