This was discussed a short while ago.  Here's how to do it:

IF you have DOS 4.00/4.01, simply use REM in front of the comment,
the same way as in *.BAT files.

Ie.
	BUFFERS=20
	REM must be at least 17 for tape drive

	DEVICE=QEMM.SYS RAM ROM EXCLUDE=E800
	REM leave hole for network adaptor

	SHELL=4dos.com

IF you have DOS 3.xx, simply put SHELL= infont of the comment,
ensuring that the TRUE SHELL= line is at the bottom of the file.
DOS does not execute this line until all others are processed,
and it only remembers the LAST such SHELL= line from the file.

Ie.
	BUFFERS=20
	SHELL= must be at least 17 for tape drive

	DEVICE=QEMM.SYS RAM ROM EXCLUDE=E800
	SHELL= leave hole for network adaptor

	SHELL=4dos.com

DOS 2.0 - 3.3 didn't have a comment character or keyword for config.sys.
This doesn't mean you can't get comments, you just get complaints about 'em.

I frequently need to switch back and forth between using QEMM and TDH386
drivers. Rather than keep to config.sys files, I just "comment" them out
using a ": " the the start of the line. This is under DOS 3.3. Under DOS 4
you can place REM blah blah blah statements in config.sys with no error 
messages.

Hope this helps....
Steve

In dos 4.00 and up you can use " REM this is a comment ".
in earlier versions you can still use the REM but it will complain
that it is not a legal command, but it doesn't hurt anything.

'REM comment ' works in Dos 4 and I believe only in Dos 4.

Beginning with MS-DOS v4.0, you can place comments in CONFIG.SYS by
beginning lines with the letters "REM"  (just like in .BAT files)

   I seem to clearly recall that starting with dos version 2.10,
it is possible to put remarks into a config.sys file.  It was documented
in PC magazine, as well as several PD software programs that make use of
this feature.  It MAY be in one of the advanced norton bibles (or similiar).
   I don't remember EXACTLY, but think it involves a line starting with
a control character, like control-X or so.

I just use "REM blah blah blah" and let DOS complain.  If I ever upgrade to
some flavor of DOS that supports REMarks, I don't have to change my
CONFIG.SYS.  (Well, I'll probably have to change it for some _other_ reason.)

You CAN use this in DOS 3.3, if you don't mind getting a "Unrecognized command
in config.sys" message.

What I do is use REM statements, and then ignore the (benign) error messages
from DOS.

Of course you can (Most people just use a "*"), but that just begs the question.

I think the SHELL= suggestion is the best...

shef@ipla01.hac.com (Ian B. Shef) (12/05/90)

To put comments in my config.sys file, I use:

break=off *** This is a comment.
break=off *** This is another comment.

Something of a kludge, but it works for me.
Note 1: You can use break=on if you prefer.
Note 2: The asterisks are not required; they just help to set off the comments.
        The only requirement is that "off" or "on" be followed by at least
        one space.
