OSINDMS6 - INSTALLING MS-DOS 6 UPGRADE ON OS/2 2.X 12/19/94 ================================================================ INSTALLING THE MS-DOS 6 UPGRADE TO CO-EXIST WITH OS/2 2.x ================================================================ Please Read Entire Document for Full Explanation of Procedures ---------------------------------------------------------------- Start the system from the current version of DOS installed, not from an OS/2 VDM or VMB. A: Prepare the Uninstall Diskette: The Uninstall diskette safeguards the files on the computer while you install MS-DOS 6. The Uninstall diskette protects the files if SETUP cannot finish installing, or if you encounter problems with MS-DOS 6 after SETUP. You can restore your previous version of DOS if you need to. 1. Write "Uninstall #1" on the label of a formatted diskette compatible with drive A. If you are using 360K diskettes, you might need two diskettes. Label the second "Uninstall #2". B: Disable Disk-Caching, Delete-Protection, and Anti-Virus Programs: Some disk-caching, delete-protection, and anti-virus programs conflict with SETUP. You do not need to disable the startup command for the MS-DOS SMARTDrive program. 1. Edit the DOS CONFIG.SYS and AUTOEXEC.BAT files. Type REM and a space at the beginning of each command line that starts a disk-caching, delete-protection, or anti-virus program. Save these files. C. Disable Automatic Message Services: 1. Disable any automatic message service, such as a network popup or a printing notification, that prints directly to the screen. These message services are incompatible with SETUP. 2. Save the changes to the CONFIG.SYS and AUTOEXEC.BAT files. 3. Press Ctrl+Alt+Del to restart the system. 4. Run SETUP. After you set up MS-DOS 6, EDIT the CONFIG.SYS and AUTOEXEC.BAT files and remove the REM commands you added previously. RUNNING SETUP --------------------------------------------------------------- OS/2 DUAL BOOT: 1. Start the system in DOS, not OS/2 VDM or VMB. 2. Insert MS-DOS 6 SETUP Diskette 1 in drive A or B. 3. Type: A:SETUP or B:SETUP at the DOS C:> command prompt. 4. MS-DOS 6 finds non MS-DOS operating system files (OS/2) on the drive and prompts you to remove the files from the hard disk. If you choose to remove the files, MS-DOS 6 re-partitions the entire first hard disk as one MS-DOS partition, removing OS/2 from the system. Select "DO NOT REMOVE THE FILES". 5. MS-DOS warns that the "Operating system on the drive (OS/2) may be disabled". Ignore this message. Select "CONTINUE SETUP". 6. Follow the prompts on the screen. If you have questions about the procedures or options press F1 for Help. 7. When SETUP prompts you for the Uninstall diskettes, insert the diskettes in drive A. 8. Restart the system when you complete the SETUP program. The system should start in MS-DOS 6. 9. To go to the OS/2 partition type: BOOT /OS2. 10. Copy COMMAND.COM from the C:\DOS directory to the C:\root directory. This lets you boot back to DOS when you are in OS/2. --------------------------- NOTE: SETUP places your previous DOS files in a directory named OLD_DOS.x. If you are sure you do not want to restore your previous version of DOS, you can delete the OLD_DOS.x directory and its filess by typing DELOLDOS at the command prompt. OS/2 BOOT MANAGER: 1. Start the system in DOS, not OS/2 VDM or VMB. 2. Insert MS-DOS 6 SETUP Diskette 1 in drive A or B. 3. Type: A:SETUP or B:SETUP from the DOS prompt. (Do not install directly from A or B). 4. MS-DOS 6 detects a non MS-DOS partition and states that "This partition will not be available when using MS-DOS 6". Ignore this message. Select - CONTINUE SETUP. 5 Follow the prompts on the screen. If you have questions about the procedures or options, press F1 for Help. 6. When SETUP prompts you for the Uninstall diskettes, insert the diskettes in drive A. --------------------------- NOTE: SETUP places your previous DOS files in a directory named OLD_DOS.x. If you are sure you do not want to restore your previous version of DOS, you can delete the OLD_DOS.x directory and its contents by typing DELOLDOS at the command prompt. TO MAKE THE OS/2 BOOT MANAGER PARTITION ACTIVE AGAIN: 1. Type FDISK at the MS-DOS 6 C:> command prompt. The FDISK OPTION screen appears. 2. Select 2 and press ENTER. The Set Active Partition screen appears. The Boot Manager partition appears as a 1-MB non-MS-DOS partition. 3. Select the number that corresponds with the Boot Manager partition, and press Enter. 4. When the confirmation screen appears, press Esc. The Fdisk Options screen appears. 5. Press Esc to exit FDISK. 6. Restart your computer, your Boot Manager should be active. WARNING *************************** At the end of the installation process, Microsoft's DOS 6.0 installation program suggests that you run the "Microsoft DEFRAG", and the "Microsoft DOUBLE SPACE" utilities. These utilities are NOT COMPATIBLE with the OS/2 environment, and may cause data loss in OS/2 if run on partitions accessible by OS/2 while running in the Microsoft DOS 6.0 environment. Microsoft DOS 6.0 utilities that perform direct diskette I/O (eg. Interlink, undelete) are NOT SUPPORTED under OS/2. These utilities compromise OS/2's filesystem. *************************** If you followed the above steps and are still having having an installation problem with MS-DOS 6, but not with OS/2, please contact the Microsoft Corporation Technical Support Center. ---------------------------------------------------------------- IBM disclaims all warranties, whether express or implied, including without limitation, warranties of fitness and merchantability with respect to the information in this document.
