       BACKGROUND.
       
       The MS-DOS 6.0 setup program may fail if MS-DOS 6.0 is already
       installed and drive C is compressed with Stacker 3.1.  Under this
       configuration, MS-DOS 6.0 setup cannot identify your hard disk's
       startup partition.
       
       SOLUTION
       
           Disable swapping of drive C
           Restart your computer and set PATH to the compressed boot
             drive
           Run MS-DOS SETUP /E or SETUP /Q
           Enable swapping of drive C and restart your computer
           Modify SYSTEM.INI and PROGMAN.INI
            
       Disable swapping of drive C
       
        1. Insert Stacker Disk 1 into drive A or B.
        2. Change to the floppy disk drive by typing A: (or B:) and
           pressing <Enter>.
        3. From the DOS prompt, type STACKER and press <Enter>.
        4. Note the drive letter of the uncompressed drive which is
           exchanged with C (your boot drive).  The drive letter is
           displayed in the far right column.
        5. From the DOS prompt, type
       
                \TOOLS\STACINI drive:
       
           where drive: is the letter of the uncompressed drive.
        6. Change the swap parameter on the line C:\STACVOL.DSK from SW
           to NS.
       
                    C:\STACVOL.DSK,NS
       
        7. Press Ctrl+Z to save the file.
            
       Restart your computer and set PATH to the compressed boot drive
       
        1. Restart your computer.
        2. At the DOS prompt, type:
       
                    PATH=drive:\DOS;drive:\;drive:\WINDOWS
       
           where drive is the letter of the drive which is exchanged
           with C.
            
       Run MS-DOS SETUP /E or SETUP /Q
       
       Select the appropriate installation procedure.
       
        TO REINSTALL MS-DOS 6.0
       +-----------------------------------------------------------------+
       |1. To reinstall all of MS-DOS 6.0, run SETUP /Q from Setup       |
       |   Disk 1.  After the welcome message, setup displays default    |
       |   system settings:                                              |
       |                                                                 |
       |       DOS Type:      MS-DOS                                     |
       |       MS-DOS Path:   C:\DOS                                     |
       |       Display Type:  VGA                                        |
       |                                                                 |
       |2. Change MS-DOS Path to the drive which is exchanged with C.    |
       |   For example, if C swaps with H, change the path to H:\DOS.    |
       |                                                                 |
       |       MS-DOS Path:   H:\DOS                                     |
       |                                                                 |
       |3. Follow the instructions on your screen.                       |
       +-----------------------------------------------------------------+
        
        TO INSTALL OR RECONFIGURE MS-DOS 6.0 OPTIONAL PROGRAMS
       +-----------------------------------------------------------------+           
       |1. To install or reconfigure MS-DOS 6.0 optional programs Anti-  |
       |   Virus, Backup, or Undelete, run SETUP /E from Setup Disk 1.   |
       |2. Follow the instructions on your screen.                       |
       +-----------------------------------------------------------------+            
       
       ENABLE SWAPPING OF DRIVE C AND RESTART YOUR COMPUTER
       
        1. Insert Stacker Disk 1 into drive A or B.
        2. Change to the floppy disk drive by typing A: (or B:) and
            pressing <Enter>.
        3. From the DOS prompt, type
                \TOOLS\STACINI C:
        4. Change the swap parameter on the line C:\STACVOL.DSK back to
           SW.
       
                    C:\STACVOL.DSK,SW
       
        5. Press Ctrl+Z to save the file.
        6. Restart your computer.
            
       MODIFY SYSTEM.INI AND PROGMAN.INI
       
       MS-DOS 6.0 includes optional programs for Windows.  If you
       installed or reconfigured these options running SETUP /E as
       described in this document, then you must modify your SYSTEM.INI
       and PROGMAN.INI files.
       
        1. Edit the file PROGMAN.INI in your Windows directory.  Find
           the line:
       
               Group=drive:\DOS\WNTOOLS.GRP
       
           where drive is the letter of the uncompressed drive which is
           exchanged with C.  Change drive to C:
       
               Group=C:\DOS\WNTOOLS.GRP
       
        2. Save the file.
           
           NOTE:  If you start Windows before making this modification,
           you will get the error "Cannot open program group file
           drive:\DOS\WNTOOLS.GRP'.  Load it in the future?"   Click
           YES, then make the modification.  Program Manager will
           correctly display the Microsoft Tools program group the next
           time you start Windows.
       
        3. Edit the file SYSTEM.INI in your Windows directory.  Find
           the VFINTD.386 line in the [386Enh] section:
               
               [386Enh]
               .
               .
               ;======== MS-DOS 6 Setup Modification - Begin ========
               device=drive:\DOS\VFINTD.386
               ;======== MS-DOS 6 Setup Modification - End ========
        
           where drive is the letter of the uncompressed drive which is
           exchanged with C.  Change drive to C:
       
               device=C:\DOS\VFINTD.386
        
        4. Save the file.
           NOTE:  If you start Windows before making this modification,
           you will get the error "Cannot find a device file that may
           be needed to run Windows in 386 enhanced mode.  You need to
           run the Setup program again.  drive:\DOS\VFINTD.386  Press a
           key to continue."  Press any key, then change your SYSTEM.INI
           file.
