Hello !
A full installation is covered by CDs 1 and 2. If you choose /kdei (kde internationalization packages) you also need CD 3. CD 4 contains the /extra set which is not used by the installer. Packages from that set are installed manually :)
Thanks for the information. The installer only asks for the next CD, would it be possible to add something like "Please insert next CD Nr. X" to the message ? CU
