Thanks to Andy Green & William Hooper, but I found somewhere in Fedora notes that Fedora binaries are optimized for Pentium Pro, but would work for Pentium, too. Anyhow, in my opinion, your suggestions are quite appropriate. Now the question arises, how do I install Fedora as i586 binaries, because I do not intend to recompile glibc, SysVinit and whatever other packages which I would need (X11, ssh, openmotif...). I have tried to install Fedora on Pentium machine, but it did not work, failed somewhere after package selection, probably at the point of partitioning/formating file-systems. There was an error message from Python, with bug report possibility, but I did not report it. (The problem is probably that machine has only 80 MB memory). So, how do I install Fedora as i586 (or i386) binaries? Thanks.
