means 13, a first switch 14, and a second switch 15.

The system maintenance/updating device 1 performs maintenance or updating of the information processing system 2 and maintains the information processing system 2 .

The system initial load device 5 performs initial settings when starting the operation of the information processing system 2. Normally, the system initial load device 5 performs initial settings to bring the system into the state necessary for starting operation, especially when starting a new system operation. , perform initial settings after performing the restore process. When this process is performed, the operating system of the system is reloaded from the system storage medium 6, and the state of the information processing system 2 is set to the complete initial state.

The system storage medium 6 is a medium that stores the operating system of the information processing system 2.

The stored operating system is loaded into the information processing system 2 by the system initial load device 5 and executed.

The input/output device 7 inputs a request for execution of processing by the second means 12 and displays and outputs information returned from the second means 12.

The first means 11 is activated after the execution of the system maintenance/updating device 1, checks the processing performed by the system maintenance/updating device 1, and determines whether the processing will prevent the restoration processing from being performed the next time the information processing system 2 is started up. If it is something that should not be
a first switch 14 on the main memory 3 of the information processing system 2;
Then, the second switch 15 on the auxiliary memory 4 is turned on. Otherwise, the first switch 14 and the second switch 15 are turned off.

The second means 12 is activated by a request from the input/output device 7 and switches the first switch 1 on the main memory 3 of the information processing system 2.
4 and the state of the second switch 15 on the auxiliary memory 4 and outputs the state to the input/output device surface 7.

The third means 13 is incorporated as part of the system initial loading device 5 and is activated at the beginning of the execution of the device.

The activated third means 13 checks the status of the first switch 14 on the main memory 3 and the second switch 15 on the auxiliary memory 4 of the information processing system 2, and if each switch is on, the system initial load device is activated. 5 Specify execution of the helis door process and end the process. Otherwise, the process ends. After the processing is completed, control is transferred to the system initial loading device 5.

The first switch 14 exists on the main memory 3 of the information processing system 2 and stores whether it is in an on state or an off state. The state of the switch is updated by the first means 11. Also the first
Referenced by means 11 and third means 13.

The second switch 15 is the auxiliary memory 4 of the information processing system 2.
It stores whether it is on or off. The state of the switch is updated by the first means 11. Also the first
Referenced by means 11 and third means 13.

Next, the operation of the system restore control device of this embodiment configured as described above will be explained in detail.

First, the system maintenance and update device 1 performs maintenance on the information processing system 2 . After this, the first means 11 is executed. The first means 11 checks the processing performed by the system maintenance/updating device 1, and if the processing requires restoration processing at the next system startup, the first switch 14 existing on the main memory 3; The second switches 15 on the auxiliary memory 4 are both turned on. Further, if there is no need for restoration processing at the next system start-up, both the first switch 14 existing on the main memory 3 and the second switch 15 existing on the auxiliary memory 4 are turned off. When the processing of the first means 11 is finished, the execution of the system maintenance and update device 1 is finished.

When the execution of the system maintenance and update device 1 is completed, the information processing system 2 is temporarily stopped and restarted. The system initial load device 5 is executed to start up the system. When the system initial load device 5 is executed, the built-in first means 11 is executed and checks the status of the first switch 14 existing on the main memory 3 and the second switch 15 existing on the auxiliary memory 4. . If both of the switches are in the on state at this time, it is determined that a restore process has been requested to the system initial load device 5, and the system initial load device 5 is prompted to execute the restore process. If only one of the switches is on or both of the switches are off, a notification is given not to perform the restore process. When the system initial load device 5 receives the notification from the third means 13 as to whether or not to perform the restore process, it executes the store process and transfers the information from the system storage medium 6 to the information processing system when performing the restore process based on the notification. 2
Reroute the system.

The second means 12 operates independently of the first means IL and the third means 13, and receives a request from the input/output device 7 to check the states of the first switch 14 and the second switch 15. The second means 12 that receives the request from the input/output device 7 stores the first
A process of reading the states of the switch 14 and the second switch 15 on the auxiliary memory 4 is executed. Thereafter, the status of each switch is output and displayed to input/output bag #7.
