NOTE:  The numeric values representd as xxxx will vary.

Add the following line to your AUTOEXEC.BAT file so that DTR.COM runs
automatically when you boot the computer.

     DTR

Both DTR.COM and AUTOEXEC.BAT should be on your boot disk.  Refer to your
MS-DOS documentation for more information on AUTOEXEC.BAT.

To create an AUTOEXEC.BAT file, you will need to be at an A:> prompt with
your MS-DOS boot diskette in the drive and follow the instructions below:

 copy con autoexec.bat <ENTER>
 set dmconfig=c:\desk <ENTER>

Then press the <F6> function key, that will produce a carot next to the
capital letter Z.  Then press <ENTER>

If you already have an autoexec.bat, follow the instructions listed here 
from the A:> prompt with your MS-DOS boot diskette in the drive:

edlin autoexec.bat <ENTER>
*li <ENTER>
1*set dmconfig=c:\desk <ENTER>
*e <ENTER>
