PURPOSE:To decide a starting mode without any manual operation by comparing the contents of an initial storage area with those of a power recovery storage area to perform a switching operation at the time of start and maintaining and updating the data contents at the start of the power recovery. CONSTITUTION:The contents of the initial storage area 20 are compared with those of the power recovery storage area 30 at the time of starting a system. When the coincidence is secured between both contents, the system is started with the start of the power recovery. When to coincidence is obtained between both contents, the system is started by an initial starting operation. Then the contents of the area 20 are copied to the area 30. Therefore the initial start or the power recovery start is automatically carried out and at the same time the new data contents of the power recovery start are always maintained and updated in the area 30. Thus a starting mode is decided without any manual operation. |
