Some applications would only run in a certain version of MS-DOS. If you run that application in DOSBox, you would get an error message similar to "Incorrect MS-DOS version". Because of this, DOSBox must be able to make the application think that it's running under a certain version of MS-DOS.
What application?

The MS-DOS utilities, such as "XCOPY.EXE" and "MORE.EXE".
use the ones of freedos who don't have such a stupid check installed.

All MS DOS utilities check the precise DOS version for no reason (so they work only in their own DOS version). DOSBOX reports itself as MS DOS 5 (so utilities from MS DOS 5 should work). As QBIX said, FreeDOS utilities do not do that (and they are freely available).

just wondering why don't make dos version selectable into config file...
no need for it.
more accurate answer.
dos varies from version to version
changing the version might break stuff as dosbox internal emulation is locked to the 5.0 features. Which are enough for all dosgames.
increasing/lowering the numbers will change the excact specification dosbox has to adhere to.

Well, there is a reason. Some MS-DOS utilities depend on undocumented calls that could change from version to version or were not available in previous versions, so MS had a policy of always checking for the underlying DOS version on every utility, whether necessary or not.

I haven't tried Setver in DosBox but you could try it. Doubt it would work tho.
