                UPGRADING FROM MS-DOS 6.22'S DISK COMPRESSION
                          (Applies to Stacker 4.0)

      BACKGROUND
      
      MS-DOS 6.22 is provided with a disk compression utility called
      DriveSpace. Stacker does not convert DriveSpace drives to Stacker
      drives. You may setup Stacker on a DriveSpace drive by
      uncompressing it and then running the Stacker Setup.
      
      SOLUTION
      
       1.  Uncompress the DriveSpace drive in accordance with the
           documentation included with the software. If you try to run
           the Stacker Setup before uncompressing the drive, you will
           receive the error message: "Cannot open x:\DBLSPACE.000".
           Setup will not give any error messages specific to
           DriveSpace.
           
                                  IMPORTANT
       Do not try to rename the DRVSPACE.XXX file to DBLSPACE.000 and
        convert the renamed file or rerun the Stacker Setup. You will
                                 lose data!
                                      
       2.  Run the Stacker Setup in accordance with the directions in
           the Stacker User's Guide.
       3.  After Setup, the system will restart. You will receive some
           error messages, and the Stacker drive may not load. This is
           easily corrected.
       4.  Change to the DOS directory. Type:
           ATTRIB -S -H -R C:\DRVSPACE.BIN <enter>
           DEL C:\DRVSPACE.BIN <enter>
       5.  Restart your system. Stacker will load and your system will
           start normally.
