    	       Bravo MS Drive Bay Adapter on the Secondary Controller

    PROBLEM

    The drive bay adapter may not work on the secondary controller, on the
    Bravo MS system, with a CD-ROM on the primary controller.

    CAUSE

    The drive bay adapter does not work because it is set as a "master" device,
    and for this reason can only be put as the master device on the secondary
    controller.  This, combined with a CD-ROM on the primary controller, stops
    DOS from seeing the first device on the secondary controller.  DOS can only
    allocate a drive letter for a device on the secondary controller, if there are two
    hard drives on the primary controller.

    SOLUTION

    There must be two hard drives on the primary controller to use a drive bay
    adapter on the secondary controller.
