Abstract: PROBLEM TO BE SOLVED: To provide a method of switching a boot device of information processing equipment capable of making maintenance personnel easily switch the boot devices with strictly performing security control for the information processing equipment not equipped with an input device. SOLUTION: In the information processing equipment not equipped with a man-machine interface for inputting, a step to short-circuit an output port and an input port, a step S12 to output a confirmation signal from the output port when activating power supply to or restarting the information processing equipment, a step S13 to determine whether the signal is input to the input port or not, a step S14 to switch a boot start of OS to a second boot device when the signal is input to the input port, and a step S19 to switch the boot start of OS to a first boot device when the signal is not input in the input port are performed.

Abstract: PROBLEM TO BE SOLVED: To reduce power consumption without spoiling user's convenience. SOLUTION: An information processor is equipped with a central processing unit and an external storage having a drive control unit which reads or writes a recording medium according to a request from an OS. The drive control unit is equipped with; a power supply control section which transmits a connection state response indicating the connection of the external storage to the information processor to the OS and stops the supply of power to the drive control unit when receiving the connection state request inquiring whether or not the external storage is connected to the information processor from the OS; a request proxy receiving section which receives the connection state request to the drive control unit from the OS instead of the drive control unit when the supply of power to the drive control unit is stopped; and a request proxy reply section which returns that the external storage is connected to the information processor when receiving the connection state request.
