There are Xeons build on the Coppermine core (the same as the P3), but if you are migrating to a newer type of Xeon (nocona, for instance) then you could run into problems. Even if your machine boots without problems, it will probably lead to reduced performance. After all, you compiled everything for a P3. Unless you don't have another choice, I would suggest you start over again and compile everything for your new Xeon. Cheers, Jorn
