Abstract
Abstract A method for starting up a recording and reproducing apparatus connected to a host computer. The method involves allowing the host computer to receive necessary programs from the recording and reproducing apparatus illustratively upon power-up, whereby the apparatus is started up. When the recording and reproducing apparatus is powered, the controller of the host computer transfers first a bootstrap program and then an initial program loader from the apparatus to the host computer, and loads the transferred programs into a RAM of the latter for startup operation.
