Installing Boot MGR, and Real DOS 4/29/94
TITLE: MOVING OS/2 2.0 FROM THE C: PARTITION TO THE D:
PARTITION ON PRE-INSTALLED PERSONAL SYSTEMS (PS).
NOTE: This method is not fully tested nor supported by IBM
OS/2 Development at this time. IBM recommends that PS
owners purchase the OS/2 BACKUP DISKETTES FOR
PRE-INSTALLED SYSTEMS. These diskettes do not include
PRODIGY or MSWORKS. To purchase these diskettes, call
the ordering line at 1-800-3IBM-OS2 (US) or
1-800-465-7999 (Canada).
DESCRIPTION OF PROBLEM:
Unable to add MS DOS to a preinstalled OS/2 2.0 system.
SUMMARY OF RESOLUTION:
The following procedures will allow a pre-loaded, 80MB,
system to be converted to a Boot Manager system with an 18MB
primary partition (C:) for DOS and a 55MB logical partition (D:)
for OS/2 2.0. This is intended to be an example. Users should
adjust their partition sizes based on their hardware
configurations and their software requirements. Some DOS
applications will only install on the C: partition. Therefore,
a sufficient C: partition size should be created to accommodate
DOS applications with this restriction.
If you have a Pre-Installed PS\1 with PRODIGY and MSWORKS,
then the OS/2 partition should be a minimum of 80MB. If you
have installed additional applications then the partition sizes
should be increased respectively. In this example, we are
assuming there is only one hard drive and the drive's formatted
capacity is 80MB. Please read this entire document before
beginning any modifications to your system.
DETAILS OF RESOLUTION:
NOTE: You will lose any customization made to your desktop.
1. The first step is to prepare your system for a backup of the
C: partition. Begin by removing the printer icons from your
desktop according to the steps below. DO NOT remove the
PRINTER template icon from the TEMPLATES folder. After you
have removed all of the printer icons, then begin a COMPLETE
backup of your system.
* See the documentation (Making Backup OS/2 Diskettes) which
was shipped with your system for the complete instructions on
creating a backup of your system.
After you have made a complete backup then continue with
these procedures. If you do not backup your system, you may
lose all of your software. If you have already made your
backups then you would want to delete the printer icons as
soon as you have the OS/2 software up and running again.
Deleting Printer Icons
----------------------------------------------------------------
A. Place the mouse on top of the printer icon.
B. Press the right mouse button once and a menu should appear.
C. Select Delete from the menu with the left mouse button.

button.
NOTE: Do not shred the printer icons.
2. There are two copies of the CONFIG.SYS on the hard drive.
One is in the C:\ root directory and the other is in the
C:\OS2\INSTALL subdirectory. Both files should be modified
to change the C: partition references to the D: partition.

Both C: and D: partitions are unformatted at this point.
The next step is to format these partitions.
A. Remove all diskettes from the floppy drives. Insert the

If you have three Utility Diskettes then insert Utility
Diskette 3 into drive A:
E. Type: FORMAT C: and press the ENTER key.
F. Proceed with the format of the C: Drive.
G. Type: FORMAT D: and press the ENTER key.
H. Proceed with the format of the D: Drive.
I. Type: SYSINSTX D: and press the ENTER key.
9. Restore OS/2; see your documentation.
(Restoring Backup OS/2 Diskettes)

10. DO NOT ATTEMPT TO BRING UP OS/2 2.0 AT THIS POINT.
11. Copy the modified files from the floppy to the OS/2 Extended
Logical Drive:

pages 75-76, steps 6 through 11 only. (Recovering From a
Corrupted User INI File)
13. Remove any diskette from the A drive.
NOTE: If you are not ready to install DOS at this time you can
reboot the system and continue with step 17 below.
14. Installation of DOS:
A. Insert your DOS installation diskette into drive A:.
B. Press and hold the CTRL+ALT+DEL keys to restart the system
and follow your instructions for installing DOS.
15. After DOS is installed, remove any diskette and press the
CTRL+ALT+DEL keys to restart your system.
16. The Boot Manager menu should appear. If the Boot Manager
Menu does not appear as expected, when you start the system,
you will need to make the Boot Manager partition startable.
Do the following:
A. Insert Utility Diskette 1 into Drive A and press the
CTRL+ALT+DEL keys to restart your system.
B. When the IBM Logo screen appears, remove Utility Diskette
1 from drive A.
C. Insert Utility Diskette 2 into drive A and press Enter.
D. When the command prompt appears (A:\), remove Utility
diskette 2, and press CTRL+ALT+DEL to restart your system.
17. Select OS/2 2.0 from the Boot Manager menu. If you did not
delete your printer icons before you made your OS/2 backups,
they should be deleted at this point.
18. There are several additional files which still contain
references to the C: drive. These should be updated before
trying to run any of your applications. They include the
following:
D:\OS2\MDOS\WINOS2\PROGMAN.INI
D:\OS2\MDOS\WINOS2\ATM.INI
D:\OS2\MDOS\WINOS2\WIN.INI
There may not be any C: references in the WIN.INI file,
unless a Windows** application has been installed. For
example, if MSWORKS** was installed on the machine then the
WIN.INI file would need to be edited and the
D:\OS2\MDOS\WINOS2\MSWORKS.INI would also need to be edited.
If you have installed any other windows applications, they
too may have INI files which need to be edited. We cannot
provide exact commands in this case, because each user can
have a different set of INI files based on which
applications have been installed by the user.
A. Open an OS/2 Window as described in Step 2, A-C.
B. Edit each of the files above by typing in E <filename>
where <filename> is the path and filename of the files
listed directly above.
C. Follow the steps for Using the SYSTEM EDITOR for each file
listed above.
If you have opened the Enhanced System Editor (EPM) then the
file D:\OS2\EPM.INI should be deleted. To delete the file.
Type the following and then press the Enter key:
DEL D:\OS2\EPM.INI
The next time the application is executed the EPM.INI file
will be recreated.
19. If the Welcome folder no longer appears on the desktop. You
may request the Welcome fax from the OS/2 Support Line which
will assist you in regenerating the Welcome folder.
20. To recreate the printer icons complete the following.
A. Open the WELCOME folder.
B. Open the CONFIGURATION TOOLS.
C. Select the CONFIGURE icon.
D. Select the box next to PRINTER.
E. Select the OK button.
F. Locate your printer driver from the list of supported
printers. Select the printer from the list.
G. Select the OK button.
H. Select the OK button when prompted to continue with the
configuration change.
I. You will now need to do a formal SHUTDOWN and the printer
will appear on the desktop when you reboot.
NOTE: If you experience problems with a printer icon setup
which previously worked, then Delete all of your printer
icons. From an OS/2 Window, change directories to the
DLL subdirectory under the OS/2 directory by typing the
following and then press the Enter key: CD D:\OS2\DLL.
Locate the printer driver subdirectories by typing:
DIR /ad and then press the Enter key.
For each printer subdirectory execute the following:
NOTE: The directories denoted by . and .. are pointers and not
real directories.
A. DEL DIRNAM\*.* and press the Enter key.
(where DIRNAM is one of the names returned by the DIR
command.)
B. Reply with Y.
C. RD DIRNAM
D. Repeat A-D until all of the printer directories have been
deleted.
21. Now SHUTDOWN the system and reboot the machine with the
Utility diskettes. Remake the system INI files; see the
Installation Guide pages 75-76, steps 6 through 11 only.
(Recovering From a Corrupted User INI File)
After you have completed this then reboot OS/2 from the hard
drive and create your printer icons as described above.
