I just downloaded knoppix from one of the mirrors on this site.
it stated it was an ISO file but after it finished downloading I realised it was in fact a rar
file containing the folder and file contents of a knoppix CD. There is two folders in there
and 5 files - I copied them files and folders directly to disk - with the same directory structure as they were in the rar file.

now,
knoppix doesent boot when I start my system with the CD in the drive. (I have changed the bios).
if I put the CD in while Windows XP has already booted it just opens up a web browser and displays
the index.html file which is on the disk.

anyone know what I may be doing wrong?

Many Thanks.
