      BACKGROUND
      
      If you're using a CD-ROM, you may have to reconfigure it to use a
      new drive letter.  Most CD-ROMs are assigned drive letters by the
      MSCDEX.EXE program through AUTOEXEC.BAT, after Stacker drive
      letters are assigned.  If your drive letter has changed as a
      result of installing Stacker, you may need to reconfigure your CD-
      ROM to use the next letter.
      
      CONFIGURING THE CD-ROM FOR MS-DOS 6.0 AND STACKER 3.1
      
      If you use MS-DOS 6.0 and Stacker 3.1, the easiest way to
      maintain pre-Stacker drive letter assignments is to have Stacker
      start assigning drive letters at a later point.  For example, if
      your pre-Stacker configuration used letters C through E, you can
      tell Stacker to start assigning new drive letters with drive F.
      
      1. From a DOS prompt, type:
      
              C:\STACKER\STACKER <Enter>
          
         Note the drive letter of the uncompressed drive which is
         exchanged with C (your boot drive).  In this example it is
         drive F:
      
              drive C: was drive C: at boot time [ F:\STACVOL.DSK =
                                                  100.0MB ]
      2. Type:
              
              C:\STACKER\STACINI drive: <Enter>
          
         where drive: is the uncompressed boot drive letter.
       
      3. Press <Enter> to insert a new line.
       
      4. Arrow up to the new line and type:
              
              /BD=drive
          
         where drive is after the last drive letter you wish to
         preserve.  For example, if you want to maintain the pre-
         Stacker identity of drives C through E, use /BD=F
       
      5. Press CTRL+Z to save the STACKER.INI file.
       
      6. Restart your computer.
       
      CONFIGURING THE CD-ROM FOR ALTERNATE VERSIONS OF STACKER OR DOS
      
      If you're not using MS-DOS 6.0, or if you're not using Stacker
      3.1, you must reconfigure the CD-ROM to use the next drive letter
      after Stacker.  For example, if your Stacker configuration uses
      letters C through F, you can reconfigure the CD-ROM as drive G.
      
      1. Edit your CONFIG.SYS file.  The lines and sequence should be
         something like this:
      
              DEVICE=C:\DOS\SETVER.EXE
              DEVICE=C:\STACKER\STACKER.COM  C:\STACVOL.DSK
              DEVICE=C:\STACKER\SSWAP.COM C:\STACVOL.DSK /SYNC+
              DEVICE=<CDROM DRIVER COMMANDS>
          
         where <CDROM DRIVER COMMANDS>  is your CD-ROM device driver
         and switches.  The CD-ROM driver line is already in your
         CONFIG.SYS file - just make sure that it loads after
         SSWAP.COM as shown.
      
      2. Type C:\STACKER\STACKER to identify the drive letters
         used at boot time.  For example, if STACKER shows that you
         are using drives C through F, then G is the next available
         drive letter.
      
      3. Edit your AUTOEXEC.BAT file.  The MSCDEX line has this
         general format:
      
              MSCDEX /D:name /M:x /V /L:letter /E
      
      4. Change letter to the next available drive letter.  If G is
         the next drive letter, the line now looks like this:
      
              MSCDEX /D:name /M:x /V /L:G /E
      
         Save the file and restart your computer.
      
      5. Verify that the CD-ROM is active by loading a CD and
         checking its contents.  For example, if your CD-ROM is drive
         G, type DIR G:  from DOS, or click on the G drive icon in
         Windows File Manager.
       
      6. Re-setup any applications or programs that have to recognize
         the CD-ROM drive letter automatically.
