I have a Targa desktop with this processor, and I have always had problems installing Fedora x86_64 on it. Yesterday I managed to install FC-6 in text mode (on the 6th try) by including no packages. (I later added what I needed with "yum groupinstall".) I'd be interested to know if anyone has had similar problems with this CPU, or alternatively had no problems installing Fedora. The machine seems to work perfectly well (under Fedora and Windows) except during installation. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
