I think its a matter of getting the 'source' for the ISO. Then you add what you need and rebuild the ISO. i.e. If I understand it correctly an ISO is a like a 'binary' program. In that you dont modify the binary. Instead you alter the source and recreate the program. I have looked into this for the SWORD project and thats how its done there. I would suspect Knoppix is similar. -derek Ted Gould said: > Hey, > > How would I add a file to an ISO (specifically Knoppix).
