TITLE   :MS-DOS Upgrade Setup Doesn't Detect @ Symbol in AUTOEXEC.BAT

-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 6.22 
-------------------------------------------------------------------------------

SUMMARY
=======

If a command in your AUTOEXEC.BAT file has a leading at sign (@), MS-DOS 6
Upgrade Setup does not analyze the line. For example, if you have "@CALL
C:\PCKWIK\SUPERON" in your AUTOEXEC.BAT file, MS-DOS 6 Upgrade Setup does not
detect the PC-KWIK cache. As a result, you end up with two disk caches loaded at
the same time.

NOTE: This problem does not occur with MS-DOS 6.2 Upgrade Setup because it
correctly analyzes lines with leading @ signs. However, during the updating of
your AUTOEXEC.BAT file, the @ sign is removed.

MORE INFORMATION
================

Microsoft does not recommend running two disk caches; be sure to disable one
before you run Setup. To disable PC-KWIK, edit the AUTOEXEC.BAT file with an
ASCII text editor, such as MS-DOS Editor, and add the remark statement (REM) in
front of the command for PC-KWIK. For example:

   rem @call c:\pckwik\superon

Additional query words: 6.22 6.00 6.20 pckwik pc kwik quick symbol
