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.
Claims2
A method for starting up a recording and reproducing apparatus, said recording and reproducing apparatus being connected to a host computer, said host computer comprising at least a first controller and a first RAM, said recording and reproducing apparatus comprising at least a second controller, a ROM accommodating a bootstrap program, a second RAM and a disk drive for driving disks having an initial program loader recorded thereon;
- said method comprising the steps of:
- causing said second controller to load said bootstrap program from said ROM into said second RAM when said recording and reproducing apparatus is powered;
- notifying said host computer by said second controller of completion of the loading of said bootstrap program form said ROM into said second RAM;
- causing said first controller to load said bootstrap program from said second RAM into said first RAM in accordance with said bootstrap program;
- and
- loading said initial program loader from said disks into said first RAM via said second RAM on the basis of said bootstrap program loaded into said first RAM, whereby said recording and reproducing apparatus is started up.
