- 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.
