In the following list, find the item that best describes your situation,
and then go to the appropriate heading for instructions.

Removing OS/2 Warp from a Preloaded PS/2 System
-----------------------------------------------
Remember: The OS/2 Warp BonusPak needs OS/2 Warp to work. It might not
function properly with other versions of the operating system.
If you are removing OS/2 Warp to use OS/2 2.0, 2.1, or 2.11:
1. Create a backup of your OS/2 Warp system (use the Diskette Factory).
2. Back up any files that you want to keep.
3. Begin the installation of the OS/2 operating system. When prompted,
choose to FORMAT the partition containing OS/2 Warp. Formatting
deletes all files in the partition.
4. Complete the installation.
Removing OS/2 Warp Using OSDELETE with Either Utility or Installation
Diskettes
---------------------------------------------------------------------
You can remove OS/2 Warp using either the Installation diskettes or
utility diskettes. If your computer came with OS/2 Warp already
installed, there is a program for creating utility diskettes on the
hard disk. For information about creating utility diskettes, press F1
or click on the Help push button. To close the Help window, press Esc.
See the User's Guide to OS/2 Warp for additional information.
Notes:
* If your system is set up with Dual Boot, start the procedures
from DOS.
* If you are using Installation diskettes, copy OSDELETE.EXE
from the OS2\INSTALL\BOOTDISK subdirectory to Diskette 1.
Note: If you are adding files to Diskette 1 and need more
space, you can erase the following files from the COPY
of Diskette 1and use that diskette:
* For a non-Micro Channel system: IBM2.* files
* For a Micro Channel system: IBM1.* files
1. Insert either the Installation Diskette or Utility Diskette 1; then
press Ctrl+Alt+Del.
2. When prompted, remove the diskette and insert either Installation
Diskette 1 or Utility Diskette 2; then press Enter.
Note: If your system created three Utility diskettes,
insert Diskette 3 instead of Diskette 2.
3. At the A:\ prompt, type OSDELETE and press Enter. A message appears
stating you have requested to remove OS/2.
4. When asked "Do You Wish To Continue?," press Y. A message appears
stating that files will be removed from the system.
5. When asked "Do You Wish To Stop Now?," press N. A message appears
asking which partition you wish to remove.
6. Type the partition letter of the drive where OS/2 is installed (for
example, C or D); then press Enter. A message appears asking for the
serial number of your computer.
7. Enter either 0 or the serial number of your computer.
After OS/2 Warp is removed, you will be given the verification
number, 3134. You then will get a message stating that the operating
system no longer resides on the computer, and you will be directed
to insert a system diskette.
8. Remove the diskette; then start the system in DOS.
Note: If you are going to re-install OS/2 Warp, insert the
Installation Diskette and restart the system. If your
system came with OS/2 Warp preloaded, contact the
vendor to obtain the full set of Installation diskettes.
