STACKER NOTE                                                   STACKER NOTE
Title: Upgrading to DR DOS 6.0 with Stacker Installed.
STAC FAX Index #2302 - 2/20/92                          
___________________________________________________________________________

Background.

   STACKER has been found to be compatible with DR DOS 6.0. This note
   outlines the procedure for upgrading your system to DR DOS 6.0 when
   Stacker is already installed.

   This procedure is NOT required if the following conditions are true:

   1. Stacker has not yet been installed.  Install DRDOS 6.0, then Stacker.
   
   2. The boot drive is NOT being SSWAPped, AND there is enough room on the 
      uncompressed drive C: (3 MB) for the DR DOS 6.0 files. In this case, 
      simply boot up with the DRDOS 6.0 STARTUP diskette and run INSTALL.

Installation Procedure.

   NOTE: This procedure assumes that:
       1. Drive C: is the boot drive.
       2. It may or may not be SSWAPped with a Stacker drive
       3. There is enough disk space (3MB) on the Stacker drive to install
          DR DOS 6.0.

   In the following sequence of steps, you will need to know which drive
   letter refers to your boot drive and which drive letter refers to your
   Stacker drive. Type  C:\Stacker\Stacker   <ENTER>  to display the Stacker
   drive map. The drive map will look similar to the following example:

   Stacker Disk Mount Utility - Stac Electronics, Carlsbad, CA 
   Stacker drive map:
   Drive C: was drive D: at boot time  [ D:\STACVOL.DSK = XX.XMB  ]
   Drive D: was drive C: at boot time  
  
   No available replaceable drive(s).
    
   The boot drive is the drive that "was C:" at boot time. If drive C: was 
   drive C: at boot time then the drives are not swapping.

1.  Remove the read-only attribute from files already on the system.
    Please insert your Stacker diskette into drive A: (or drive B:). If you
    are using the 5.25" Stacker Diskettes you will need to insert the Utility
    Disk (Disk #2). Change to the diskette drive by typing A: (or B:) and 
    pressing Enter. Then type the following commands :

    SATTRIB  -R  C:\CONFIG.SYS         <ENTER>
    SATTRIB  -R  C:\AUTOEXEC.BAT       <ENTER>
    SATTRIB  -R  C:\COMMAND.COM        <ENTER>

    (In the next command, substitute the name of your DOS directory if it
    is named something other than \DOS.)

    SATTRIB  -R  C:\DOS\COMMAND.COM    <ENTER>

    In the following four commands, if drive C: is swapping, remember to
    use the boot drive letter you found above to replace the drive letter
    x:. If drive C: is not swapping, use the drive letter of your Stacker
    drive in place of x:.

    SATTRIB  -R  x:\CONFIG.SYS         <ENTER>
    SATTRIB  -R  x:\AUTOEXEC.BAT       <ENTER>
    SATTRIB  -R  x:\COMMAND.COM        <ENTER>

    (As before, in the next command, substitute the name of your DOS
    directory if it is named something other than \DOS.)

    SATTRIB  -R  x:\DOS\COMMAND.COM    <ENTER>

2.  Copy the CONFIG.SYS and AUTOEXEC.BAT files to the Stacker drive.
    If drive C: is swapping, type the following:

    REN C:\CONFIG.SYS CONFIG.STA               <ENTER>
    REN C:\AUTOEXEC.BAT AUTOEXEC.STA           <ENTER>
    COPY x:\CONFIG.SYS C:\                     <ENTER>
    ( x: is the boot drive swapping with C:)   
    COPY x:\AUTOEXEC.BAT C:\                   <ENTER>
    ( x: is the boot drive swapping with C:)   

    If drive C: is not swapping, type the following:

    REN x:\CONFIG.SYS CONFIG.STA               <ENTER>
    ( x: is the Stacker drive) 
    REN x:\AUTOEXEC.BAT AUTOEXEC.STA           <ENTER>
    ( x: is the Stacker drive) 

    COPY C:\CONFIG.SYS x:\                     <ENTER>
    COPY C:\AUTOEXEC.BAT x:\                   <ENTER>

3.  Insert the DR DOS 6.0 STARTUP Disk (Disk #1) in the A: drive. Then
    type the following commands:

    COPY A:\COMMAND.COM C:\                    <ENTER>
    COPY A:\COMMAND.COM x:\                    <ENTER>

    (In the next set of commands, substitute the name of your DOS directory 
    if it is named something other than 'DOS'.)

    COPY A:\COMMAND.COM C:\DOS                 <ENTER>
    COPY A:\COMMAND.COM x:\DOS                 <ENTER>

4.  Boot the system with the DR DOS 6.0 STARTUP Disk in the A: drive.

5.  At the opening screen of the DR DOS 6.0 installation, press the F10
    key to abort. Then choose "EXIT TO DR DOS" and press Enter.

6.  At the A> prompt, type the following:   SYS C:  
    The system will respond with: "Destination Disk was not formatted under 
    current Operating System. Writing new boot sector.  System files copied."

7.  Remove the DR DOS 6.0 STARTUP disk from the A: drive and reboot the
    system from the hard disk.  This will start the system with DR DOS 6.0 
    and the Stacker drive(s) will be available.  If any application is 
    automatically loaded during bootup, please exit the application and 
    return to the DOS prompt.

8.  At the C> prompt, place the DR DOS 6.0 STARTUP disk back into the A:
    driv.

9.  Type the following:  A:AUTOEXEC

10. The installation process for DR DOS 6.0 will begin.  At the opening 
    screen, press the Enter key to continue.  Choose to install DR DOS on the 
    C: drive and press Enter.  Next, select the option to "Use the information 
    in the existing file(s)."

11. You will now be asked to specify the drive letter and directory
    name to receive the DR DOS 6.0 files.  Move the cursor to the suggested
    pathname for DR DOS 6.0. If drive C: is swapping, choose drive C:; if
    drive C: is not swapping, choose drive x: (remember to substitute the
    actual drive letter for 'x:', determined above). Also, change the
    \DRDOS subdirectory to the name of your DOS directory.  This is
    because we want to overwrite the existing DOS version with DR DOS 6.0.
    Otherwise, there will be two DOS versions on the system at the same
    time.

12. Choose to "Replace all DOS files on the destination drive."

13. At this point, you may choose either to skip the configuration and
    go directly to installation, or you may choose to proceed with further
    configuration.

14. Follow the instructions displayed on your screen to complete the
    installation of DR DOS 6.0.  When DR DOS 6.0 is finished, you will be 
    given a choice to "Exit to DR DOS" or "Reboot Computer."  Choose 
    "Exit to DR DOS."

15. If drive C: is not swapping, type the following:

    COPY x:\CONFIG.SYS C:\            <ENTER>
    COPY x:\AUTOEXEC.BAT C:\          <ENTER>

    If drive C: is swapping, type the following:

    COPY C:\CONFIG.SYS x:\            <ENTER>
    COPY C:\AUTOEXEC.BAT x:\          <ENTER>

16. Remove the last DR DOS 6.0 diskette and reboot the system from the
    hard disk.

17. DR DOS 6.0 adds new commands to your existing CONFIG.SYS file. When the 
    machine is rebooted, DR DOS will ask if you want to execute any commands 
    from your previous CONFIG.SYS. This will particularly affect the Stacker 
    lines. Hit 'Y' to each of the questions about loading the Stacker 
    drivers. When the system has completed booting, use your favorite text 
    editor (or the DR DOS EDITOR program) to remove the '?' from in front of 
    the Stacker lines. You will also need to examine any other lines which 
    have been so marked. These changes need to be made to the CONFIG.SYS file 
    on the uncompressed drive. After making these changes, copy the 
    CONFIG.SYS file to the Stacker drive.

    Also during bootup, you may see a "Bad or missing file..." message as
    DR DOS attempts to find a DOS program or driver not copied to the
    uncompressed drive during the installation process. Simply copy the
    missing program file(s) from your DOS directory on the Stacker drive
    to the directory on the uncompressed drive where DR DOS is looking.

    For example, if you were previously loading the DOS file 'ANSI.SYS'
    from the 'DOS' directory on the uncompressed drive, type the following
    to update 'ANSI.SYS' to the DR DOS 6.0 version (as before, substitute
    the name of your DOS directory if it is named something other than
    \DOS:

    COPY C:\DOS\ANSI.SYS x:\DOS   (drive C: is SSWAPping)
    or
    COPY x:\DOS\ANSI.SYS C:\DOS   (drive C: is not SSWAPping)

    There may be other programs from the previous version of DOS on the
    uncompressed drive which will need to be replaced with the equivalent 
    DR DOS programs. You will need to search both the root directory and the 
    DOS directory for these programs.

18. Finally, some files from your previous DOS version may still be located 
    in your DOS directory. These files have no corresponding replacement in 
    DR DOS 6.0. Please examine them and consult your User's Guide to see if 
    they can be deleted. Be careful not to delete anything which may be 
    required for normal operation of your system. Type the following to 
    display a list of these files (substitute the name of your DOS directory 
    if it is named something other than \DOS):

    DIR C:\DOS /A | FIND /V "8-23-91" | MORE  (drive C: SSWAPping)
    or
    DIR x:\DOS /A | FIND /V "8-23-91" | MORE  (drive C: not SSWAPping)

    If you would like to send this listing to the printer, simply add the
    characters  > PRN  to the end of the above lines.

    WARNING !! - DO NOT delete the files TASKMAX.INI, VIEWMAX.INI, or
    DRDOS.INI. These files are critical to the correct operation of DR DOS
    6.0. They will be included in the above listing because these files are
    customized during installation and, therefore, the dates of these files
    will be the date of your installation of DR DOS 6.0.
