      BACKGROUND
      
      If your system starts with a solid color background and the OS/2
      clock as the mouse cursor, then you will need to rebuild the OS/2
      desktop in order to start the system properly. Refer to your OS/2
      documentation for background and details. When the boot drive is
      compressed, extra steps are needed in addition to the ones
      outlined in the OS/2 documentation.
      
      SOLUTION
      
      To rebuild the desktop you need:
      
         - Stacker-aware boot disks.
         - A copy of the OS/2 file CHKDSK.COM. With OS/2 2.1, CHKDSK is
           on OS/2 distribution Disk 2 (the third disk in the package).
           If you installed OS/2 Warp from Compact Disc, CHKDSK is on
           the CD in the \OS2IMAGE\DISK_2 directory. It may be in
           different locations depending on the version of OS/2 you are
           using.
           
      If you do not have a set of Stacker-aware boot disks, you can
      create them. You will need:
      
         - The first two disks of the OS/2 distribution set
           (Installation Disk and Disk 1).
         - The Stacker for OS/2 and DOS Disk 1.
         - A blank reusable floppy disk of the same type as the OS/2
           distribution disks.
           
      To create Stacker-aware boot disks:
      
       1.  Perform a DISKCOPY of the OS/2 distribution disk that
           contains the CONFIG.SYS file. It's usually the floppy disk
           labeled "Disk 1". Then mark the copied disk "Stacker-aware
           Disk 1".
       2.  Start your system under DOS. Use a floppy boot disk if
           necessary.
       3.  Insert the Stacker for OS/2 and DOS Disk 1 in drive A or B
           and switch to that drive.
       4.  Type:
           STACBOOT <Enter>
       5.  STACBOOT will prompt you to enter the names of the drives
           that are compressed. For example, if you compressed C and D,
           you would type:
           C D <Enter>
       6.  You will then be prompted to insert the OS/2 disk containing
           CONFIG.SYS into drive A. Insert the disk you marked "Stacker-
           aware Disk 1" into drive A and press <Enter>.  STACBOOT will
           then advise you to remove the disk from drive A. You now
           have a set of Stacker-aware boot disks.
           
      Rebuilding the Desktop with OS/2 2.x, or if you have not
      activated Warp's Archive feature:
      
      Note: If you are running OS/2 Warp, and have activated Warp's
      Archive feature, go to the next section.
      
      Important: Unless you modified the CONFIG.SYS file located in the
      OS2\INSTALL directory to properly reference all Stacker drives on
      your system, DO NOT attempt to revert to the Original Desktop by
      holding down ALT+F1 keys when OS/2 is loading.
      
       1.  Restart your system with the OS/2 installation disk in drive
           A. When prompted for disk number 1 insert the disk you
           labeled "Stacker-aware Disk 1".
       2.  When prompted to continue with the OS/2 installation press
           ESCAPE (F3 if you are using OS/2 Warp) to get to a command
           prompt.
       3.  Insert the disk containing CHKDSK into drive A (or the CD-
           ROM drive if appropriate.) Change to the drive and directory
           where CHKDSK is located. Type:
           CHKDSK d: /F <Enter>
           where d is the OS/2 boot drive.  Make sure there are
           no errors.
       4.  Change to the OS2 directory on your OS/2 boot drive. If it
           is drive C, for example type:
           C:<Enter>
           CD\OS2 <Enter>
       5.  Remove the System and Read-Only attributes from the OS2.INI 
           and OS2SYS.INI files. Type:
	   ATTRIB -S -R OS2*.INI <Enter>
       6.  Rename the existing OS2.INI and OS2SYS.INI files. Type:
           REN OS2.INI OS2INI.BAD <Enter>
           REN OS2SYS.INI OS2SYS.BAD <Enter>
               Rebuild the INI files. Type:
           MAKEINI OS2.INI INI.RC <Enter>
           MAKEINI OS2SYS.INI INISYS.RC <Enter>
       7.  Delete the file WP ROOT. SF which is hidden in the root
           directory of the drive. Type:
           ATTRIB -S -H -R \WP?ROOT.?SF <Enter>
           DEL \WP?ROOT.?SF <Enter>
           Note that the WP ROOT. SF file may not be present, and you
           will receive an error message that the file could not be
           found. If so, simply proceed to the next step.
       8. Restart the system from the hard drive. You should then see
           the OS/2 tutorial on your desktop.
           
      To rebuild the desktop with OS/2 Warp if you have activated the
      Archive feature:
      
      If you have activated Warp's Archive feature (chapter 15 of the
      OS/2 Warp User's Guide), Stacker updates the "archive" CONFIG.SYS
      with the Stacker device drivers. Therefore, you may be able to
      restore a recent version of the desktop.
      
       1.  Restart the system. Press the ALT+F1 key when a small white
           box appears in the upper left corner of your screen.
       2.  When the Recovery Choices screen appears, choose to restore
           the latest archive boot files. The latest files are normally
           restored by pressing the numeral "1" key. See Chapter 15 of
           the OS/2 Warp User's Guide for details on using this
           feature.
       3.  If the desktop fails to return, try restoring older archive
           files.
       4.  When your desktop returns, your latest changes to the
           desktop may not be displayed. You must recreate these
           changes manually.
       5.  If this procedure fails, use the procedures in the previous
           section.
