Since 3.4 (not the CT edition) ,at boot (livecd) there seems to be a control of the checksum activated.
Indeed ,when I add,remove or alter some files directly on the iso ,
I receive a checksum error at boot .
How can I turn this off ?
There doesn't seem to be any cheatcode available.
Any help on this one would be apreciated ...

Before on the 3.3 version this went perfect.

So now all of a sudden ?????

PS. don't give the link on how customize knoppix ,because what I only need is to add some files and shellscript to the cd. Nothing more.
