Abstract
In a computer system, when the system is first booted in a normal mode, main memory data stored in a main memory immediately after the system is booted, is stored as backup data in a backup memory or the like. A backup flag representing whether or not the backup data can be restored is set and the system is rebooted. When the system is next booted in the normal mode, the backup data stored in the backup memory or the like is restored as the main memory data in the main memory. The backup flag is automatically reset in a maintenance mode.
