Does anyone know how to determine whether the current DOS running is MS-DOS
(from Microsoft and used on clones) or IBM-DOS (aka PC-DOS from IBM and
used on true blue boxes) from within a Microsoft C program?

I know how to determine the version number but do not know how to determine
origin... Thanks...todd
