Abstract

If a system configuration turns back to the system configuration which was once set up previously, it is not required to set up the system configuration through user interaction. In a data processing system having a non-volatile memory for staring information on system configuration also after the system is turned off, if information on new system configuration is set up, the newly set up information is stored not only unto a predetermined area of said non-volatile memory, but also into a second non-volatile memory such as a disk storage apparatus, etc.
different from said non-volatile memory or an area other than said predetermined area of sand non-volatile memory and if changes to the system configuration axe detected, for example, at a self-diagnostic test at the time of the supply of power to the system, a check of whether or not information that accords with the information on the current system configuration exists in said second non-volatile memory or the area other than said predetermined area of said non-volatile memory, i.s made and if accordance is obtained, the appropriate information is transferred to said predetermined area of said non-volatile memory.
