control.xml / software tag

Hi, I am trying to modify a control.xml from a default installation CD. I have changed the software tag to something like: <selection_type config:type=”symbol”>fixed</selection_type> <base>Minimal</base> But it seems to be ignored. The installer just shows: ? (161.3 MB total) I have also tried to preselect another base category, which also is ignored. Any Ideas? Marcus PS: Perhaps I have to mention that I have removed the desktop_new module from the control file.
