Title: Installing the IBM Corrective Service Diskettes on a  
       "Stacked" hardisk.   
STAC FAX Index #2303 - 3/26/92

Background.

    The key to installing these new programs is to NOT boot up from the IBM 
    Corrective Service Diskettes (as the instructions indicate), but instead 
    to simply boot normally, thereby having the Stacker drives mounted and 
    available.

Procedure.

1.  Begin the process by inserting the first IBM Corrective Service Diskette 
    (CSD), into the A: diskette drive (this procedure will not work from the 
    B: drive or any other external floppy drive). If you can only install 
    from your B: drive (due to broken A:, etc), you can use the ASSIGN command 
    to switch the drive letter specifications.

2.  Run the 'AUTOEXEC' file. It contains the command 'UPDATE x' where 'x' 
    represents the number of Corrective Service Diskettes to be run from 
    the update package (UPDATE.COM is an IBM program on the first CSD).

3.  The README file will automatically be displayed. Continue to press any 
    key until the end of the README file is reached.

4.  At the prompt:
      
    Enter your keyboard code:(press 'Enter' to accept the default of 'US').

5.  At the prompt:

    Enter the drive which contains DOS 5.0 files to be replaced: ( enter 
    the drive letter which contains the directory or directories you wish 
    to update and press 'Enter').

6.  The next information displayed will indicate whether the target drive is 
    or is not 'IBM DOS version 5.0'. This indicates the presence of the
    DOS system files in the root directory of the drive.

    If the following prompt appears:

    "Target is IBM DOS version 5.0. Do you want to replace the DOS files in 
     all directories (Y/N)?"

    Then press 'Enter' to accept the default of 'Y'.

7.  If the following prompt appears:

    "Target is NOT IBM DOS version 5.0 Be sure to specify your IBM DOS 
     5.0 subdirectory. Enter the target directory name (\path):"

    Then enter the name of the DOS directory (including the '\').

    The system will begin the automated process by first 'SYS'ing the drive 
    if the IBM system files were previously detected. It will then continue 
    by replacing the appropriate IBM DOS 5.0 files it can find in the root 
    directory and subdirectories.

8.  The user will then be instructed to:

    "Insert next IBM DOS Corrective Service Diskette into drive A: 
     Press any key to continue..."

    This sequence will be repeated until all the Corrective Service Diskettes 
    have been processed and the various update programs copied to the 
    respective directories.

9.  When the procedure is finished, the user will be prompted either to:

    "Remove IBM DOS Corrective Service Diskette from drive A: 
     Press any key to restart system..."

     or to choose:

     "Another target directory name (Y/N)?" if updating a 'NON IBM DOS' drive.

10. If there are more drives or directories to update, the user then restarts 
    the procedure by changing to the diskette drive and re-running 'UPDATE x' 
    again, this time choosing a different drive letter or directory to update.
    If you are "swapping" the C: drive with Stacker, then you will want to 
    to update the uncompressed/host drive as well.  To see which drive is
    swapping with C:, run SWAPMAP.


    There have been sporadic problems reported with the UPDATE program 
    hanging the system when pressing 'Enter' after entering the drive letter 
    to update. In every instance, the solution has been to remove the 
    diskette, reboot the system and restart the procedure once again. 
    The second time, everything goes OK. This problem is not destructive.
