Abstract
An electronic apparatus having a ROM disposed in a data processing apparatus, and a writeable and nonvolatile memory device storing an operation setting value of the ROM is provided. When powered on, the apparatus determines whether the ROM has been changed or replaced. If it is determined that the ROM has been changed, the apparatus writes the initial values of the ROM into the memory device. Thereby, the device eliminates the need for a person to perform the rewriting operation on the writeable and nonvolatile memory device even when the ROM has been replaced.
