REMOVING OS/2 2.X Manually 6/09/94
File:REMOVE.fax
TITLE: Removing OS/2 2.X from your system
DESCRIPTION OF SYMPTOMS:
In certain cases it will be necessary to remove OS/2 from your
system manually. For instance, 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. (To boot back
to DOS from OS/2 2.0 follow the instructions on page 30 of the
installation guide; from OS/2 2.1 follow the instructions on page 48
of the installation guide). If you are unable to boot back to DOS,
follow the steps in the section "PUTTING DOS BACK ON YOUR
SYSTEM" at the end of this fax.
SUMMARY OF 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.
DETAILS OF RESOLUTION:
1. Execute the following steps to remove any hidden files that may
exist in the OS2\BITMAP directory (i.e., C:\OS2\BITMAP):
CD OS2\BITMAP
ATTRIB -s -h aaaaa.*
ERASE aaaaa.*
2. Remove all OS/2 specific directories. This includes the
following directories:
\OS2
\SPOOL
\PSFONTS
\NOWHERE
\DESKTOP <-- may be DESKTOP2, DESKTOP3, etc.
\OS!2_2.0_D <-- the OS/2 2.0 Workplace Shell directory
Note: This process can be expedited by using a program that
removes entire directory trees, such as the DOS Shell.
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,
execute the following steps:
a) Insert the Installation disk into drive A.
b) Reboot the computer.
c) When prompted to do so, remove the Installation disk and
insert diskette 1, then press <ENTER>.
d) When the Welcome screen is displayed, press ESC to
display the command prompt.
e) Remove diskette 1 and insert diskette 2 (the diskette that
contains the CHKDSK command).
f) Type the following at the command prompt:
CHKDSK C: /F
and press Enter. (If your operating system resides on a drive
other that C, use the appropriate drive letter instead).
g) Remove the diskette from drive A and reboot the system.
CAUTION: If you are going to be reinstalling OS/2 2.X with the dual
boot option, you MUST be able to boot DOS from your hard drive
before proceeding. See the next section if you need help on putting
DOS back on your system.
PUTTING DOS BACK ON THE SYSTEM
------------------------------
You may put DOS back by reinstalling your DOS package, or an
easier way is by using the DOS SYS command. To use the SYS
command, execute the following steps:
a) Boot up a DOS bootable floppy disk.
b) If the SYS.COM file isn't already on your disk, copy it from
your DOS directory on the hard drive onto your disk.
c) Execute the following command to make your hard drive
bootable again:
SYS C:
d) If you have a backup copy of the DOS CONFIG.SYS and
AUTOEXEC.BAT copy them into the root directory (i.e., C:\),
overwriting the OS/2 CONFIG.SYS and AUTOEXEC.BAT. If you
don't have a backup, and installed OS/2 in a dual boot
configuration, you may execute the following step to retrieve
the ones that OS/2 kept for you:
COPY C:\OS2\SYSTEM\CONFIG.DOS C:\CONFIG.SYS
COPY C:\OS2\SYSTEM\AUTOEXEC.DOS C:\AUTOEXEC.BAT
e) At this point you should be able to boot into DOS from the
hard drive.
