Hi Eberhard Thanks for this contribute. IOWarrior seems a nice interface for the FOX Board users so I would ask to you if you can add more info on your web site so I'll link it on the Dev.Workshop page (http://www.acmesystems.it/?id=33) or, if you prefere, I can get your material to make a new tutorial on the Acme site.
