      BACKGROUND
      
      If your Stacker coprocessor was installed and working when you
      installed Stacker 4.0, you can set up Stacker to continue using
      it by following these instructions.
      
                                    Note
         Stac supplies the AT/16 LZS server file on the Stacker 4.0
      distribution disks. If you are using either the XT/8 or the MC/16
      coprocessor, you can obtain the appropriate server file from the
                     Stac BBS or from Stac on Compuserve
                
      SOLUTION
      
          -Configuring the LZS Server.
          -Running daignostic software to test base addresses.
           
      Configuring the LZS Server
      
      To continue using your Stacker coprocessor after installing
      Stacker 4.0, you need to determine the base address for your
      coprocessor, add a line to your CONFIG.SYS file and restart your
      computer.
      
       1.  Determine the base address for the card by viewing your
           STACKER.INI file.
               a.  Change to your STACKER directory.
               b.  Type ED and choose STACKER.INI from the File menu.
               c.  Write down the number after the /B=. This is the
           base address for your coprocessor. The possible base
           addresses for the AT-16 Coprocessor are:
                          200, 220, 240, 260, 280, 2A0, or 2E0
          The possible base addresses for the XT-8 Coprocessor are:
                  C400, C800, CC00, D000, D400, D800, or DC00
           You must use the same base address to ensure that your
           coprocessor continues to function.
           The MC-16 Coprocessor does not require a base address in the
           CONFIG.SYS.
       
               d.  The /B switch has no effect in the STACKER.INI
           file. Move the cursor to this line and press Delete
           repeatedly to remove it.
               e.  Choose Save from the File menu to save the file.
       2.  Now edit your CONFIG.SYS file.
               a.  Choose CONFIG.SYS from ED's File menu.
               b.  If you are using MS-DOS 6.X, PC-DOS 6.X, or Novell
           DOS 7, add a line immediately before the line that begins
           with "DEVICEHIGH." and ends with "STACHIGH.SYS": (If you are
           using any aother DOS version, add this line before the line
           that has the filename STACKER.COM in it.)
           If you have the AT-16 Coprocessor, type
           DEVICE=C:\STACKER\LZS_AT16.SYS /B=base address
           If you have the XT-8 Coprocessor card, type
           DEVICE=C:\STACKER\LZS_XT8.SYS /B=base address
           where base address is the number from the /B line in the
           STACKER.INI file.
           If you have the MC-16 Coprocessor card, type
           DEVICE=C:\STACKER\LZS_MC16.SYS
               c.  Choose Save from the File menu and then choose
           Exit.
       3.  If you obtained either the LZS_XT8.SYS or LZS_MC16.SYS file
           from the Stac BBS, you must copy the file to the C:\STACKER
           directory.
       4. Restart your computer to put the change into effect.
           
      Running diagnostic software to test base addresses
      
      If you were unable to determine your base address using the
      procedures above, you may use the diagnostic file included with
      the LZS server to test the possible base addresses. If you have
      the AT-16 card, the file is SDIAG_AT.EXE. If you have the XT-8
      card, the file is SDIAG_XT.EXE. If you have the MC-16 card, the
      file is SDIAG_MC.EXE. The example below will assume that you are
      using the AT-16 card.
      
       1.  At the DOS prompt , type:
           SDIAG_AT BASE ADDRESS
           where base address is an address number from the list above
           that you wish to test. For example:
           SDIAG_AT 200
       2.  Continue testing each address until you find one that
           passes. Use that base address in the CONFIG.SYS line above.
       3.  The configuration for your MC-16 card is contained on your
           reference disk from your original installation.
