OK. i586 is the very original Pentium (AKA Pentium I, AKA P5) and Pentium MMX. i686 (AKA P6) is anything later, including Pentium II. > > > and it isn't really needed anyway. > > Now *that's* right. You'll get a bit more performance with the right > kernel, but you should boot fine on a Pentium II with a 586 kernel. An i586 kernel will run on an i686, but the instruction-sequencing optimizations for i586 are unique to that chip. Also, P6 has some more instructions. I know there will be a performance gain moving to an i686 kernel, but I don't know how noticable it will be. If you have a P6, you definitely want the i686 glibc, as it supports NPTL threads, which the i386 library does not. You also want the i686 openssl package. The best way to upgrade kernel and glibc is probably to boot from a rescue disk. Then you can make RPM update the system mounted in /mnt/sysimage. I *think* you want "rpm -Fvh --force --root /mnt/sysimage <package-name>", but I wouldn't swear to it. > > The original poster, Tony, needs to post some of his errors for us to > take a look at if we are to help. > > James. > -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu http://www.math.clemson.edu/~mjs
