Pentium 4 CPUs (unless they have an M in them somewhere -- then it gets screwy) can run Pentium III code. No need to rebuild the whole system if you don't want to. Chances are you'll need a new kernel, but that's all. CFLAGS wise, -O2 -fomit-frame-pointer -pipe -march=pentium4 should do. If you have lots of cache (sorry, dunno the Xeon cores off the top of my head), you might gain from -O3 under certain circumstances, although we'll probably ask you to try -O2 and no -fomit-frame-pointer if you submit any bugs like that :) -- Ciaran McCreesh Mail: ciaranm at gentoo.org Web: http://dev.gentoo.org/~ciaranm
