   No, programs that check the DOS version use int 21h, function 30h to
check the version number.  What they care about isn't what version of DOS
the disk was formatted under, but rather what version of DOS is currently
running.  The rationale for this is that different versions of DOS have
slightly different sets of function calls, so it may depend on a function
call that's present in DOS 4.01 that isn't in DOS 3.30, for example.
