I tried to get cpuburn but had difficulty finding an .rpm of it. In the process of searching I found a lot of cautions that it can damage hardware. Therefore I decided to leave this issue for the Clinic this Sunday. I also need to do a dist-upgrade from Fedora 16 to Fedora 18, which I will also do at the Clinic. By Sunday the PSU winter term will be completely over so I can risk goobering up my main computer. Also, my replacement 3TB Go Flex Desk hard drive should be here so I can use it to do a complete backup before commencing the scary stuff. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
