Hi Sebastian, Yeah in Red Hat 9, just click the "start" menu with the red hat icon and select "System Settings" from the first menu followed by "Add/Remove applications". You will then be prompted for a root password followed by a list of packages you currently have installed on your system. You should see a category on this list called "kernel development". Select that and click ok, then you should be all set. I hope this helps :-) ~~Nick > Dear all, > > last days I updated my system with up2date dor the first time.
