Background. 

    Stacker drives are 'mounted' at boot time by a device driver in the 
    Config.sys file.  If you were to boot from a "plain vanilla" system 
    disk, which had no Config.sys file or Stacker device driver statement(s), 
    your Stacker drives would appear to be no more than large hidden files 
    on the hard disk.  Creating a boot disk that enables access to the 
    Stacker drives involves making a DOS startup disk, then creating a 
    Config.sys file on that disk which contains the Stacker device drivers.  
    This note outlines the required steps to create such a disk.

Procedure.

1.  Making the startup disk:

    A. Create a DOS startup disk by inserting a formatted diskette in 
       drive A: and typing:
       
       SYS C: A:

       Note: If you are running DOS 3.x, you will need to copy Command.com
       to drive A: after 'sys'ing the disk.  
   
    B. Next, copy Config.sys from your hard disk to this diskette.
       For example, at the command prompt type: 
       Copy C:\Config.sys A:            <ENTER>

       This disk is now capable of starting the system and mounting the 
       Stacker drives.  (It is not necessary, but you may wish to copy 
       C:\Autoexec.bat to this disk as well).

2.  Making a Stacker diagnostic disk:    
   
    You may wish to make this disk more "plain vanilla" for trouble shooting 
    purposes.  Just edit Config.sys with your favorite text editor and 
    eliminate all but the Stacker device drivers.  For example, to modify 
    Config.sys using Stacker's text editor, type:
    
    Stacker 2.0  -  C:\STACKER\SEDIT  A:\CONFIG.SYS     <ENTER>
    Stacker 3.0  -  C:\STACKER\ED     A:\CONFIG.SYS     <ENTER>
    
    You should now see a listing of the Config.sys contents.  Locate the 
    Stacker device drivers.  They will look similar to:
    DEVICE=C:\STACKER\STACKER.COM C:\STACVOL.DSK   
    DEVICE=C:\STACKER\SSWAP.COM   C:\STACVOL.DSK /SYNC

    Now delete all but these Stacker devices.  For example, if you are using
    SEDIT (Stacker 2.0), or ED.EXE (Stacker 3.0) position the cursor at the 
    beginning of the line using the arrow keys. Now press  <Ctrl> K    
    to delete the line.  Repeat for all the lines you wish to delete.  When 
    you are finished, press <Ctrl> Z to save the file.

    Note: If you are using a device driven drive such as a Hardcard or 
          CD-ROM, or have non-DOS partitions requiring device drivers, you 
          will need to leave their device lines in the Config.sys file.
