thanks for your fast reply

no, unfortunately it's not the solution - the error-message changes
but it is still the same problem: knoppix does not find what it needs
'no file /knoppix/etc/ld.so.cache'

i have this feeling i have to edit miniroot.gz and to mount the iso there but
as i am a complete newbie i do not feel comfortable with that.

so, if anybody has a simple solution?

cheers
