This ID string was covered by Paul Mattias in a post several months ago. 
Several different entries were used by DRDOS, NDOS7, OPENDOS7.x, 
IBM PCDOS. 

It was not purely cosmetic and was used basically for the same reasons 
MSDOS (all versions) used it.  If you check back in the archives you 
should be able to find it and the changes he made to correct it in the 
OPENDOS/DR-DOS/DRDOS versions.

Or you could contact him at:

eMail: <Matthias DOT Paul AT post DOT rwth-aachen DOT de>

 When MSDOS ran into this ID on any DRdos versions it would trash your 
system to some extent and would not let your windows programs run
properly, 
if at all.  That was part of the lawsuit, if memory serves me right.
