ABSTRACT:
An information processing apparatus comprising a power unit, a first control unit and a second control unit in which power supply is controlled based on a control signal from the first control unit, wherein when electric power supply from the power supply unit has been stopped and then the electric power supply from the power supply unit has been started, if update of a memory of the first control unit has been instructed, the first control unit transfers the content of a flash ROM in the first control unit into the memory thus updates the content of the memory. At this time, the second control unit is kept in a power-off status by a control signal line until the update of the memory is completed. After the completion of the update, power-on is notified by the control signal line, and the reset status of the second control unit is released.
