ABSTRACT:
A device, an apparatus using the device, and a method designed for performing operations such as automatic installation of driver software facilitate expansion of the existing functions of the apparatus. A microprocessing unit, a random access memory, an operation part, a read only memory or the like are mutually connected via a system bus and mounted in main equipment which is made up of a personal computer. A media controller is connected to the system bus of the main equipment. An electronic device is connected to the media controller as a medium for executing external memory, expanding the existing function or the like, the electronic device being provided with an Ethernet providing connection to external computer networks via a media side controller and a nonvolatile memory in which driver software data driving the Ethernet under respective environments is stored.
