Error message "Incorrect DOS version" displayed when loading MSCDEX.EXE 
Ver 2.21.

Description
-----------
User who upgraded from MS DOS 5.0 to MS DOS 6.0 will encounter the above 
mentioned error message when loading MSCDEX.EXE Ver 2.21.

The reason is that MSCDEX.EXE Ver 2.21 does not recognise MS DOS 6.0 and 
thus report the "Incorrect DOS version" error when loading.

Solution/Action
---------------
The following two solutions help to solve the problem:

a.	Use version 2.22 of MSCDEX.EXE provided by MS DOS 6.0 instead of 
	MSCDEX.EXE Version 2.21 (MSCDEX.EXE Ver 2.22 can be found in the 
	DOS directory).

b.	Update the SETVER version-table to report DOS 5.0 to MSCDEX.EXE 
	instead of DOS 6.0.

	The following statements will update the SETVER version-table 
	accordingly:

	C:\> SETVER C:\DOS MSCDEX.EXE 5.00

	Then add the following line at the begining of your CONFIG.SYS file:

	DEVICE=C:\DOS\SETVER.EXE

	You will need to reboot your system to let the version-table to take effect.
