================================================================
              REMOVING OS/2 2.X FROM A SYSTEM
================================================================

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

At times, it may be necessary to remove OS/2 from a system
manually.  For example, if OS/2 has to be reinstalled, it
is recommended that the existing operating system first be
removed.  If you have installed OS/2 in a dual boot
configuration, it is important to boot back to DOS before
removing OS/2.

If you cannot boot back to DOS, instructions are in this
document.


RESOLUTION:

1. Remove any hidden files that may exist in the OS2\BITMAP
   directory.

2. Remove all the OS/2 specific directories.

3. Delete the OS/2 system files from the root directory.

4. Run CHKDSK to clear up any corruption on the drive.


PROCEDURES:

1. Type the following commands to remove any hidden files that
   may exist in the OS2\BITMAP directory, for example,
   C:\OS2\BITMAP. Press Enter after each one.

             CD OS2\BITMAP
             ATTRIB -s -h aaaaa.*
             ERASE aaaaa.*

2. Remove the following OS/2 specific directories:

             \OS2
             \SPOOL
             \PSFONTS
             \NOWHERE
             \DESKTOP      (may be DESKTOP2, DESKTOP3, ...)
             \OS!2_2.0_D   (OS/2 2.0 Workplace Shell directory)


3. Remove the OS/2 system files from the root directory:

             ATTRIB -s -r -h OS2*.*
             ERASE OS2*.*

             ATTRIB -s -r -h EA?DATA.?SF
             ERASE EA?DATA.?SF

             ATTRIB -s -r -h WP?ROOT.?SF
             ERASE WP?ROOT.?SF

4. To clear up any extended attribute problems that may occur,
   run CHKDSK:

        a. Insert the Installation diskette into drive A.
        b. Restart the system.
        c. When prompted, remove the Installation diskette and
           insert diskette 1. Press Enter.
        d. At the Welcome screen, press Esc to go to a command
           prompt.
        e. Remove diskette 1 and insert diskette 2, which
           contains the CHKDSK command.
        f. Type the following at the command prompt:

                  CHKDSK C: /F   and press Enter.

           NOTE: C: is drive where OS/2 resides
        g. Remove the diskette from drive A and restart the
           system.

CAUTION:  If you are going to be reinstalling OS/2 2.X with the
dual boot option, you MUST be able to start DOS from your hard
disk before proceeding.  Use the following instructions if you
need to put DOS back on your system.


PUTTING DOS BACK ON THE SYSTEM
----------------------------------------------------------------

You can put DOS back by reinstalling your DOS package.  An
easier way is to use the DOS SYS command.  Do the following
to use the SYS command:

1.  Start the system with a DOS bootable diskette.

2. If the SYS.COM file is not on the diskette, copy it from
   the DOS directory on the hard disk to the diskette.

3.  Type the following to make the hard disk bootable again:

               SYS C:

4. If you have a backup copy of the DOS CONFIG.SYS and
   AUTOEXEC.BAT copy them into the root directory,
   overwriting the OS/2 CONFIG.SYS and AUTOEXEC.BAT.

   If you do not have a backup, and installed OS/2 in a dual boot
   configuration, type the following to retreive the ones OS/2
   saved:

               COPY C:\OS2\SYSTEM\CONFIG.DOS C:\CONFIG.SYS
               COPY C:\OS2\SYSTEM\AUTOEXEC.DOS C:\AUTOEXEC.BAT

5. You should now be able to start to DOS from the hard disk.
