Yes, it works great...one last question to this issue:
To start Knoppix from USB I tried four options:
1) After boot prompt "Enter"
---> System boots into Adriane.
2) After boot prompt "knoppix nocomposite"
---> System boots into Knoppix 6.7 ---> OK
3) After boot prompt "knoppix nomodeset"
---> System boots into Knoppix 6.7 ---> OK
4) After boot prompt "knoppix nodrm"
---> System boots into Knoppix 6.7 ---OK

Now I wonder how I could change the USB boot file so that at least one
of the cheatcodes is included --- only because I'm too lazy to type it
each time.

Greetings
