PURPOSE:To prevent the failure of system load processing when an architecture is changed by selecting the nucleus program of an operating system corresponding to a selected architecture out of plural operating systems and loading the selected program into a main storage. CONSTITUTION:When the start of a system load process is instructed from a system console 1, a 1st program 6a is loaded into an area 5a of a main storage 5 from an external storage 6. Then the architecture of a computer is decided when the program 6a is carried out. Thus a nucleus program 6b or 6c of an operating system is selected and loaded into an area 5b of the storage 5 in accordance with the decided architecture. Thus it is possible to prevent the failure of the system load processing due to the discordance despite the change of the architecture.
