SETTING UP STACKER HARDWARE DRIVERS FOR USE WITH STACKER 3.1 AND MS-DOS 6

If your Stacker coprocessor was installed and working at the time you
installed Stacker 3.1 under MS-DOS 6, you can set up Stacker 3.1 to 
continue using it by following these instructions.

*************************************************************************

To install a Stacker hardware driver you need to:

--Copy the appropriate hardware driver to your Stacker directory
--Determine the base address for your AT/16 or XT/8 coprocessor
--Add a line to your CONFIG.SYS file
--Restart your computer


1.  First, copy the hardware driver file for your coprocessor to the
    directory that contains your Stacker files (usually C:\STACKER):

    At the DOS prompt, type one of these:

        COPY drive:LZS_AT16.SYS C:\STACKER

          or

        COPY drive:LZS_XT8.SYS C:\STACKER

          or

        COPY drive:LZS_MC16.SYS C:\STACKER

    where drive: is the drive that contains the hardware driver
    file. If your Stacker files are in a different directory,
    type its name instead of C:\STACKER.

2.  (XT/8 and AT/16 only) Determine the base address for the card by
    viewing your STACKER.INI file.

    a.  Change to your STACKER directory.

    b.  You have to examine a file on your uncompressed boot drive.
        If drive C is a Stacker drive, type:

          STACKER

        The result includes a line like this: 

         Drive C: was drive C: at boot time  [D:\STACVOL.DSK = 112 MB]

        The drive letter following the square bracket (D here) is the
        uncompressed drive letter.

    c.  Type: 

          STACINI drive

        where drive is the drive letter for your uncompressed boot drive.

    d.  Write down the number after the /B=. This is the base address for
        your coprocessor. The possible base addresses are:

        AT/16    XT/8
        -----    -----
         200     C400
         220     C800
         240     CC00
         260     D000
         280     D400
         2A0     D800
         2E0     DC00

        You must use the same base address to ensure that your
        coprocessor continues to function.

    e.  The /B switch has no effect in the STACKER.INI file. Move the
        cursor to this line, then press the Delete key repeatedly to
        remove it.
   
    f.  Press Ctrl+Z to save the file.

3.  Now, edit your CONFIG.SYS file. 

    a.  Change to the root directory of your boot drive and type:

          EDIT CONFIG.SYS

    b.  Type one of these lines immediately before the line that begins
        with "DEVICEHIGH. . ." and ends with "STACHIGH.SYS":

        DEVICEHIGH = C:\STACKER\LZS_XT8.SYS /B=base address

           or

        DEVICEHIGH = C:\STACKER\LZS_AT16.SYS /B=base address

           or

        DEVICEHIGH = C:\STACKER\LZS_MC16.SYS 

        where base address is the number from the /B line.
 
    c.  Save the file and exit the editor (Alt+F followed by X, 
        then press Enter to choose Yes).

4.  Restart your computer to put the change into effect.
