You're welcome. One comment I can make is that booting from the CD for Knoppix 6 is a much faster business than the Knoppix 5 DVD and Knoppix 6 feels snappier to use - probably because Knoppix 5 set up the mouse to move like a snail and didn't recognise double taps as a click (I was using an inspiron laptop). A much better experience with 6 (apart from the fact the CD didn't have the utility I needed) as a result.
