                      CONFIGURING FLOPPY DRIVES FOR AST SYSTEMS

    To insure proper installation of a floppy drive into an AST computer system,
    make sure the following conditions are met.  The AST diskette drive
    specification calls for "frame" ground to be connected to "logic" ground.

    On many floppy drives this is accomplished by the correct placement of a
    jumper on the drive's control electronics printed circuit board.  Refer to
    the instructions included with the drive to verify correct placement of the
    grounding jumper.

    In addition, the grounding strap from the power supply should be attached to
    the drive's metal frame during installation.  It should be noted that it may
    be necessary to move the ground strap from it's normal position on the
    Premium computer's chassis to a position where the ground connection on the
    floppy drive frame can be accessed.
