Abstract
PURPOSE:To shorten time required for the restoration of processing state by allowing an initial program loader to refer non-volatile memory defining information at the time of recognizing that the preceding end state is abnormal end, and initializing areas other than an area specified as a non-volatile memory. CONSTITUTION:The initial program loader 11 recognizes whether the preceding end state is normal end or abnormal end at the time of initial program loading IPL, and in case of abnormal end, refers the contents of non-volatile memory defining information 32, and when the non-volatile memory is defined, only the memory is not initialized. Since information stored before system down is left in the 'non-volatile memory' even when the system down or the like is generated and IPL is executed, recovery is made unnecessary or the necessity of recovery can be minimized. Thus, a recovery time at the time of system down can be shortened.
