The present invention is provided with: a processor (101); a storage medium (102) for storing an Operating System (OS) executed by the processor (101); one or more devices (104, 105) which are reinitialized upon restart of the OS; an active OS (410) which is executed at system startup to initialize the devices (104, 105), and which performs an OS process in a normal state after the system startup; and a standby OS (420) which is executed at system startup, detecting the devices (104, 105) connected to the processor (101) and then standing by after initializing the detected devices, and which, when the active OS (410) needs to be restarted because of an abnormality occurring therein, reinitializes the devices by using reinitialization data for the devices which the stand by OS (420) had stored during the initialization process before going to standby. |
