PROBLEM TO BE SOLVED: To improve the security by automatically limiting a specified operation and to improve the reliability by making risks small, by providing a machine identifier in an accessible register intrinsically provided in a server. SOLUTION: A flash ROM 102 is provided with the function of electric erasure and write by a program and a BIOS program is stored in the flash ROM 102. A main memory 103 for system management is used as an area for storing data for server maintenance and used for the checking of machine ID(identifier) discrimination by the rewrite of BIOS and the preservation of a rewrite instruction request flag from a host terminal. Then, in the case that the machine ID is not correct, since normal BIOS write is not performed, the rewrite error of mistaking data or the like is prevented and safety is provided in terms of a user operation. |
