I'm afraid that unless you tell us what
exactly isn't working (i.e. what exactly you're trying to do and which error messages you're getting etc) it's very hard to say what your problem might be. One thing you might try, though, would be to head over to the troubleshooting forum and have a look at some of the DOSBox help threads there. If none of those problems sound like the one you're having, create a new thread about it, but it's probably some very basic thing which is covered there somewhere. For example a common problem is caused by the fact that there's a mistake somewhere in the
tutorial where the directory is given as "C
OSBOX" instead of "C
OS".
