PROBLEM TO BE SOLVED: To update a BIOS without activating a dedicated system program from an FD. SOLUTION: At the time of updating the BIOS, a BIOS updating driver 102 reserves and resisters callback in an operating system(OS) 103 so as to call back a BIOS updating processing part 102-1 just before ending shutdown processing of the OS 103. The OS 103 runs a shutdown processing program 104 and calls back the BIOS updating processing part 102-1 reserved and registered beforehand in the extension. At such a time point, the shutdown processing is not completely finished but almost all programs stop operating. In such a state, the BIOS updating processing part 102-1 updates the BIOS.
