                            INSTALLING MS-DOS 6.2

      BACKGROUND
      
      The MS-DOS 6.2 Setup program may not correctly detect some
      Stacker 3.1 drives. You may have experienced these problems while
      setting up DOS 6.2:
      
        DOS 6.2 reports there must be at least 4,200,000 bytes free on
        drive C (even if you do have the space free)
        
        DOS 6.2 reports that it cannot update certain files
        
      Hopefully, Microsoft will remedy these problems in future
      releases of DOS. Meanwhile, Stac provides a simple solution. You
      need a file called 62STAC.EXE. It is available on CompuServe,
      America Online, or the Stac BBS. Use this file BEFORE installing
      MS-DOS 6.2
      
      -----------------------------------------------------------------
      Important: If you've installed MS-DOS 6.2 and can no longer
      access your Stacker drives or receive the message BAD OR MISSING
      COMMAND INTERPRETER, you'll have to temporarily uninstall MS-DOS
      6.2. Insert the Uninstall disk in drive A and restart your
      system. After DOS is successfully uninstalled, press R to restore
      the previous version of DOS. Then, follow the instructions below
      for using 62STAC.EXE and reinstalling MS-DOS 6.2.
      -----------------------------------------------------------------
      
      USING 62STAC.EXE
      
      To install MS-DOS 6.2 on your Stacker drive:
      
       1. Start you computer normally, and exit from all programs.
          Switch to the directory where you have copied 62STAC.EXE.
      
       2. Type 62STAC.EXE and press <Enter>.  This will uncompress
          three files, STAC62.TXT,  BEFORE62.EXE, and AFTER62.EXE.
      
       3. Type BEFORE62.EXE and press <Enter>.  Note:  this utility
          must be run just prior to the MS-DOS 6.2 Setup program. If
          for any reason you restart your system before proceeding to
          the next step, you must run BEFORE62.EXE again.
      
       4. Run MS-DOS 6.2 Setup per its instructions.
      
       5. When Setup is complete and the system restarts, switch to
          the appropriate directory and type AFTER62.EXE and press
          <Enter>.  MS-DOS 6.2 is now completely installed on your
          system.
