thank you very much. again, i have this question, you say: "Apt-cdrom does not work. What I reccommend is that the contents of the cdrom's be copied into four separate partitions and the /etc/apt/sources.list be edited to point to these partitions, e.g. deb file:/discs/A/debian sid main contrib local deb file:/discs/B/debian sid main contrib local etc." so i wonder :can i put these cdroms content in one partition? and the /etc/apt/sources.list is edited like the two lines upon which header with"deb file:/......"
please help me.
