Well, first of all suse isnt available "publicly" in cd image format, ie iso files, and if they are, WHERE ARE THEY?
suse make there source available to download but not cd images in an attempt at trying to make ppl buy there packages, which in the current climate of low support for linux is a good idea imo.
JetBlack: what you`ve probably got is the source code, and will have to install from source, which is a serious task for even the hardened linux whores. I suggest either buy the cd`s or find another distro if you want to install from cd.
You could always attempt a source install, but if your not comfortable with linux id advise against it.
