No recompiles on this system. It will work, almost certainly. Maybe you won't have the most optimal system after the replacement (eg running a i586 kernel on a i686, or no smp kernel (multiprocessor, also used dor hyperthreading and dual core cpus). > Reconfiguring X does concern me a bit.

If it doesn't run at all, remove /etc/X11/xorg.conf and rerun system-config-display. > > Very good point about booting into runlevel 3! > > Thanks! One thing that caused me problems in a similar situation was when the old system had an onboard network controller, as well as a pci network card, and the new hardware had just one network card. The boot sequence was hanging forever trying to initialize the non-existent eth1. But that was of course easy enough to fix from runlevel 1. David Jansen
