Abstract: A program updating method and apparatus update a system initialization code as well as a master code to a new version from a remote site. The program updating method according to the present invention includes a first step of determining whether or not the system initialization code source is executed, a second step of executing the system initialization code copy if the system initialization code source is not executed, a third step of determining whether or not a master code requires updating and thereby updating the same with a master code or a server according to the result of the above determination after the system initialization code source is executed, a fourth step of determining whether or not the system initialization code requires updating after updating the master code, and a fifth step of sequentially updating the system initialization code source/copy with a system initialization code of a server if it is determined that the system initialization code requires updating.
