                    230948-210      SONY DRIVES

    SOLUTION:       If your Advantage! system uses a Sony CD-ROM drive, and it
                    does not function properly, replace it with a Sony drive.  To
                    identify the type of drive your system uses, observe the CD-
                    ROM tray in front of the system; it has "Compact Disc" molded
                    in the middle.

                    If your Advantage! system uses a Mitsumi CD-ROM drive, and it
                    does not function properly, replace it with a Mitsumi drive.
                    To identify the type of drive your system uses, observe the
                    CD-ROM tray in front of the system; it has "Double Speed"
                    molded in the middle and "Compact Disc" molded on the right.

                    See part numbers listed above.  For additional information on
                    Sony and Mitsumi drives and drivers, see Software Bulletin #
