=======================================================================
  SYS1200 or SYS0008 Error when Starting DOS Sessions under OS/2 Warp
=======================================================================

Please Read Entire Document for Full Explanation of Procedures
--------------------------------------------------------------

DESCRIPTION

When starting the system, the following error message appears:

   SYS1200: The system cannot create the DOS environment. The error 
   code is ***.

When starting a DOS or WIN-OS/2 session, the "Cannot start..." message 
is received. In addition, when running COMMAND.COM from an OS2 Window, 
the following error message is received:

   SYS0008: There is not enough memory available to process this
   command. All available memory is in use.

RESOLUTION

Note: Make sure you have a backup of any file you intend to change.

You must selectively reinstall DOS support. Before starting, however, 
delete all files in the \OS2\MDOS subdirectory, unless WIN-OS/2 support
is installed; in this case, back up the VWIN.SYS and VW32S.SYS files in
the \OS2\MDOS subdirectory before deleting the files.

When Selective Install is complete, copy the VWIN.SYS and VW32S.SYS 
files back to the \OS2\MDOS directory. You also need to add the WINDOWS
directory to the PATH statement in the AUTOEXEC.BAT file.
 
 1. Open OS/2 System; then open Command Prompts.

 2. Select OS/2 Window; then type the following, pressing Enter after
    each:

       CD \OS2\MDOS
       COPY VW*.SYS \OS2
       DEL *.*

 3. When you see "Are you sure?," press Y.

 4. Type Exit and press Enter. This will end the OS/2 Window session.

 5. Open the OS/2 System folder.

 6. Open the System Setup folder; then select Selective Install.

 7. Select OK in the System Configuration window to get to the next
    screen.

 8. If the Multimedia Device Settings window is displayed, select OK.

 9. In the OS/2 Setup and Installation window select OS/2 DOS support.

10. Select Install.

11. Select the correct source drive, and then select Install.

12. Insert the OS/2 diskettes when prompted.  

13. Do NOT perform shutdown when prompted. Instead, open the OS/2  
    Window and type the following, pressing Enter after each: 

       CD \OS2
       COPY VW*.SYS/MDOS
       CD \
       E AUTOEXEC.BAT

    The AUTOEXEC.BAT file is displayed. At the end of the file is the
    PATH statement.

14. Add the WINDOWS directory, as follows:

       PATH C:\OS2;C:\OS2\MDOS;C:\;C:\WINDOWS;

15. Save and exit the file.

16. Shut down and then restart the system.

This should solve the problem 99% of the time, if OS/2 Warp was not 
installed over a previous version of OS/2.
