      BACKGROUND
      
      If you are using Super PC-Kwik, you may receive this error
      message on startup: "using boot sector information which differs
      from previous information...". This indicates that Super PC-Kwik
      is attempting to cache your Stacker drive. This is not necessary.
      Your Stacker drive exists as a large STACVOL.xxx file on the
      physical uncompressed drive. When the cache intercepts calls to
      the physical drive, it is also caching calls to and from the
      Stacker drive. In fact Super PCKwik is caching compressed data,
      which doubles the effective size of the cache. If you receive the
      error message above, turn off caching on the Stacker drive.
      
      SOLUTION
      
      Edit your PCKWIK.INI file with any text editor. Go to the
      [SUPERPCK] section and add the line:
           IgnoreDrive=x
      Where x is the letter of your Stacker (compressed) drive. If you
      have more than one Stacker drive, add one line for each Stacker
      drive.
