- DUALBOOT PROCEDURES for OS/2 2.X, WARP
- ================================================================
-
- Please Read Entire Document for Full Explanaiton of Procedures
- -----------------------------------------------------------------
-
- This document explains how to add DUALBOOT capability to OS/2
- and how to recover from the inability to boot from DOS to OS/2
- or OS/2 to DOS.
-
- ----------------------------------------------------------------
- USING DUAL BOOT IN OS/2 WARP
-
- When you install OS/2 Warp, using the Easy Installation method, a
- Dual Boot feature is automatically set up. Dual Boot lets you
- switch back and forth between OS/2 and DOS.
-
- Dual Boot also determines which operating system should start
- when you turn on the computer. Each time you shut down and
- restart, the computer starts in the operating system was last
- being used. For example, if you shut down your system while
- running DOS, the system starts in DOS the next time you turn on
- your computer.
-
-
- IF DUAL BOOT DOES NOT WORK IN OS/2 WARP:
-
- If the BOOT command is unsuccessful when you try to switch from
- DOS to OS/2, you may have programs running that take up too much
- memory. If so, close the programs before you use the BOOT
- command. If the programs are loaded from your AUTOEXEC.BAT file,
- you should deactivate the programs before using the BOOT command.
- ================================================================
-
- STARTING THE DUAL BOOT FEATURE IN OS/2 2.x, WARP:
-
- Use the Dual Boot function to switch from one operating system
- to another:
-
- - To switch from OS/2 to DOS:
- 1. Open OS/2 System Icon.
- 2. Open Command Prompts Icon.
- 3. Open Dual Boot Icon.
- 4. When a message appears asking if you want your system to
- be reset, type:
- Y and press Enter
-
- - To switch from DOS to OS/2:
- 1. At the DOS command prompt, type:
- C:\OS1\BOOT /OS2 and press Enter
-
-
- ================================================================
-
- ADDING DUAL BOOT CAPABILITY TO OS/2 2.X:
-
- Edit the CONFIG.DOS file.
- 1. At the command prompt, type:
- E CONFIG.DOS and press Enter
-
- 2. Type the following line tin the file:
- SHELL=C:DOS\COMMAND.COM /P /E:25 and press Enter
-
- 3. Save the file and close the editor.
- If prompted for file type select TYPE the set PLAIN TEXT.
-
- If CONFIG.DOS or AUTOEXEC.DOS do not exist, create them
- and add the above statement.
-
- 4. From an OS/2 Full screen session, type:
-
- CD C:\DOS and press Enter
- DIR COMMAND.COM and press Enter
-
- If COMMAND.COM does not show in the directory, use the
- following command to COPY it from the root directory.
-
- COPY C:\COMMAND.COM C:\DOS\COMMAND.COM and press Enter
- BOOT /DOS and press Enter
-
- A message appears asking if you wish to continue? Answer Y
- for yes. The system restart and DOS starts.
-
- After DOS starts go to a DOS prompt.
- CD C\OS2
- BOOT /OS2
-
- A message appears asking if you wish to continue? Answer Y for
- yes. System restarts and OS/2 starts.
-
-
-
- RECOVERING DUALBOOT IN OS/2 2.X: DOS TO OS/2 OR OS/2 TO DOS
- ----------------------------------------------------------------
- The following procedure allows recovery from the inability to
- DUALBOOT from DOS to OS/2 or OS/2 to DOS. This assumes the
- installation of OS/2 and DOS is completed.
-
-
- PROBLEM 1: NOT ABLE TO DUALBOOT FROM OS/2 TO DOS (hangs)
-
- PROCEDURE:
-
- 1. Start OS/2 from the hard disk.
- 2. Shutdown the system.
- 3. Insert DOS bootable diskette in drive A: and restart system.
- 4. Type the following commands, and press Enter after each one:
- C:
- COPY C:\CONFIG.SYS C:\OS2\SYSTEM\CONFIG.OS2
- COPY C:\AUTOEX0EC.BAT C:\OS2\SYSTEM\AUTOEXEC.OS2
- COPY C:\OS2\SYSTEM\AUTOEXEC.DOS C:\AUTOEXEC.BAT
- COPY C:\OS2\SYSTEM\CONFIG.DOS C:\CONFIG.SYS
- DEL C:\OS2\SYSTEM\CONFIG.DOS
- DEL C:\OS2\SYSTEM\AUTOEXEC.DOS
- RENAME C:\OS2\SYSTEM\BOOT.DOS C:\OS2\SYSTEM\TEMP
- A:
- SYS C:
- 5. Remove diskette from drive A: and restart the system.
-
- NOTE: If SYS.COM can not be found in drive A:, copy it from
- your \DOS subdirectory on the hard disk.
-
-
- PROBLEM 2: NOT ABLE TO GO FROM DOS TO OS/2 (hangs)
-
- PROCEDURE:
-
- 1. Start DOS from hard disk.
- 2. Restart system using the Installation Diskette and Diskette 1
- 3. Press Esc at the Welcome Screen.
- 4. At the A: prompt, type: C: and press Enter
- 5. Type the following commands, and press Enter after each one:
- COPY C:\CONFIG.SYS C:\OS2\SYSTEM\CONFIG.DOS
- COPY C:\AUTOEX0EC.BAT C:\OS2\SYSTEM\AUTOEXEC.DOS
- COPY C:\OS2\SYSTEM\AUTOEXEC.OS2 C:\AUTOEXEC.BAT
- COPY C:\OS2\SYSTEM\CONFIG.OS2 C:\CONFIG.SYS
- DEL C:\OS2\SYSTEM\CONFIG.OS2
- DEL C:\OS2\SYSTEM\AUTOEXEC.OS2
- RENAME C:\OS2\SYSTEM\BOOT.OS2 C:\OS2\SYSTEM\TEMP
- A:
- SYSINSTX C:
- 6. Remove diskette from drive A: and restart the system.
-
-
- NOTE: If SYS.COM can not be found in drive A:, copy it from
- your \DOS subdirectory on the hard disk.
