SD and CF on the same machine are known to play king of the hill and in some cases it disabled the first installed one from running after the latter one installs. Just ask daniel whatever his name is.
Basically you have a system problem. You want help, and the best help is just start fresh. You dont seem like the kind who likes to tinker based off of this thread, all your other threads, and the fact that you bought a G4. That is fine and all, but you may want to listen to advice when you get it from 2 independant sources to just do a reinstall. Or quit complaining.
