- REMOVING OS/2 2.0 FROM YOUR SYSTEM
- ----------------------------------
-
- This document describes how to remove OS/2 from a partition.
-
- If you have installed OS/2 in a dual boot configuration, it is important
- to boot back to DOS (by following the instructions on page 30 of the
- install guide) before removing OS/2. If you are unable to boot back to
- DOS, follow the steps in the section "PUTTING DOS BACK ON YOUR SYSTEM"
- before proceeding.
-
- TO REMOVE OS/2 2.0
- ------------------
-
- NOTE: Using a program that removes entire directory trees, such as the DOS
- Shell, makes this process a lot simpler.
-
- 1. Erase and remove all the OS/2 Specific directories
- (including subdirectories) from your hard disk, this includes
- the following directories:
-
- /OS2
- /SPOOL
- /PSFONTS
- /NOWHERE
- /DESKTOP
- /OS!2_2.O_D <--- this is your Workplace Shell directory
-
- Note: In cetain cases, the desktop directory may have a similar,
- but different directory name, remove the appropriate directory for
- your case.
-
- 2. Execute the following steps to remove the system files from the
- root directory (i.e., from the C:\ dos prompt):
-
- Note: OS/2 2.0, DOS 5.0 or later must be used for the following to work
- correctly as the -h parameter is unspecified in previous versions
- of the DOS attrib command. (An alternative would be to use a
- DOS utility that will allow you to change the hidden attribute of
- a file).
-
- 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
-
- 3. To clear up any extended attribute problems that may occur, execute
- the following steps:
-
- a) Insert the Installation Diskette into drive A.
- b) Turn on the computer. If the computer is already on, press
- and hold the Ctrl + Alt, and press Del to restart the system.
- c) When you are prompted to do so, remove the Installation Diskette
- and insert Diskette 1.
- d) Press Enter.
- e) When the Welcome screen is displayed, press Esc to display the
- command prompt.
- f) Remove Diskette 1 and insert Diskette 2 (the diskette that
- contains the CHKDSK command).
- g) To correct the errors on your hard disk, type the following at
- the command prompt:
-
- CHKDSK C: /F
-
- and press Enter. (If your operating system resides on a drive
- other than C, use the appropriate drive letter instead).
- h) Remove the diskette from Drive A.
- i) Press and hold Ctrl + Alt, and press Del to restart the system.
-
- CAUTION: If you are going to be reinstalling OS/2 2.0 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 (a DOS disk with system on it).
- b) If the SYS.COM file isn't already on your disk, copy it from your
- DOS directory on the harddrive 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:\), overwritting 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 retreive
- the ones that OS/2 kept for you (during installation for the
- purpose of dual boot):
-
- copy c:\os2\system\config.dos c:\config.sys
- copy c:\os2\system\autoexec.dos c:\autoexec.bat
-
- e) At this point you may wish to reboot to make sure that you can
- boot off your hard drive.
