It is not that they values are the problem.  The OF on 3.0 machines are =
rewriteable so by changing the load-base and real-base settings you run =
the risk of your loader leaking out of its allocated space in OF and =
writing over stuff that Apple put there that is needed by the computer to =
run.  Apple will need to rewrite the whole OF if you've done this.
