Abstract

An information processing apparatus switches between an Operating Systemand an Operating Systemduring operation and comprises: a storing unit including a first area storing data managed by OS, a second area storing a reset handler containing instructions for returning to OSand for branching to OS, and a switching unit that switches connection/disconnection of the first area with outside; a table storing unit storing information showing the reset handler's position; a CPU having a program counter and executing an instruction at a position indicated by positional information in the program counter; and a management unit that, when instructed to switch from OSto OSwhile the apparatus is operating with OS, instructs the switching unit to disconnect the first area and the CPU to reset. When instructed to reset itself, the CPU initializes its state and sets the reset handler positional information into the program counter.
