I try to build a simple xp pro with sp3integration then a newest project with automatisation of installation, the a newest with automatisation and driver installation for a notebook. I never use import or load a precedent session. When i try to build image iso with other version (Xp home) I get the feeling some parameters was preserved. I'am not familiarized wih Nlite procedures and i'am not sure. Actually i clear completely the folder and i load the original cd to build an newer project. Ideally i want to obtain an original session (ie with service pack only) and create the newer driver integration and/or automatisation based on this session. regards pxg
