hi, I am installing Fedora on ten similar machines (dual Pentium III) and on three of them the installation stopped at "checking 'hlt' instruction" and I have to switch off the machine. Using the "no-hlt" instruction, both during install and added to grub I was able to install and run Linux, but I am worried, what does it mean? And is this a symptom of something nasty in one of the CPU? Any help? Thanks, GiP
