      BACKGROUND
      
      If the file DPMS.EXE is being loaded from an uncompressed swapped
      drive, or a Stacker drive which is not swapped, you will receive
      the error message "Cannot find a device file that may be needed
      to run Windows in 386 Enhanced mode". You may correct this
      situation by modifying your CONFIG.SYS file.
      
      SOLUTION
      
         - Determine where DPMS.EXE is being loaded from in CONFIG.SYS.
         - Determine a location to place DPMS.EXE that will not cause
           an error.
         - Modify CONFIG.SYS to properly load DPMS.EXE.
           
      Determine where DPMS.EXE is being loaded from in CONFIG.SYS
      
       1.  From the DOS prompt, type: ED /C <enter>. This will bring up
           your CONFIG.SYS file in an editor.
       2.  Note the line that is loading DPMS.EXE. It will look
           something like this:
           DEVICE=X:\STACKER\DPMS.EXE
           where x is a drive letter. Write down this drive letter.
           
      Determine a location to place DPMS.EXE that will not cause an
      error
      
       1.  From the DOS prompt, type: STACKER <enter>. This will
           display a Stacker drive map.
       2.  Locate the line displaying the drive that you noted above.
           For this example we will assume this is drive D.
       3.  For the error message to occur your drive map would look
           something like one of the two examples below.
           a. If  DPMS.EXE is loaded from an uncompressed swapped
           drive:
           Drive C was drive C at boot time [ D:\STACVOL.DSK = nnnMB ]
           Drive D was drive D at boot time
              
           b. If DPMS.EXE is loaded from a Stacker drive which is not
              swapped:
           Drive C was drive C at boot time
           Drive D was drive D at boot time [ C:\STACVOL.000 = nnnMB ]
       4.  In either case, loading DPMS.EXE from drive C instead of
           drive D will solve the problem.
           
      Modify CONFIG.SYS to properly load DPMS.EXE
      
      You may also need to copy DPMS.EXE to the drive from which it
      will load.
      
       1.  Change to drive from which you will load DPMS.EXE. In this
           example, that would be drive C.
       2.  Locate the STACKER directory. If the Stacker directory does
           not exist, create it by going to the root directory and
           typing MD STACKER <enter>. Then change to the STACKER
           directory.
       3.  Copy the DPMS.EXE file from its source. In this example you
           would type:
           COPY D:\STACKER\DPMS.EXE <enter>
       4.  If you had to create the STACKER directory, also copy the
           Stacker editor. Type:
           COPY D:\STACKER\ED.EXE <enter>
       5.  Type ED /C <enter>. Again look for the DPMS line in
           CONFIG.SYS.
       6.  Change the line to load DPMS.EXE from the drive you have
           selected. In this example you would change the line to read:
           DEVICE=C:\STACKER\DPMS.EXE
       7.  Save the file and restart your system. You will now be able
           to start Windows in enhanced mode.
