	       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.
