- 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, etc.)
- \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: If your operating system is on a drive other
- than C, use the appropriate drive letter.
- 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 boot 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 boot to DOS from the hard disk.
