Correction (unfortunatly after 10 minutes we cannot edit our post...):
... if you run KNX from ISO file, the "knoppix_dir" boot option is unnecessary. But if you use the unpacked ISO to boot the system, you probably place the ISO content in a dedicated directory (not in the root of the boot device), so the path and KNX dir name must be specified. I also renamed "KNOPPIX" to "NOPIK91-FATDOG" ...
