And ft it tells you model name : Pentium II or model name : Pentium III or model name : Pentium IV you have the i686 cpu.If you get something else, you probably do not have the Pentium compatible CPU.In my case, beside the kernel, I found the following packages which need to be updated: glibc-2.3.2-27.9.i6864763 Kb Wed Apr 9 2003 nptl-devel-2.3.2-27.9.i686809 Kb Wed Apr 9 2003 openssl-0.9.7a-5.i6861095 Kb Sat Mar 29 2003 I uploaded the to /tmp directory cd /tmp wget ftp://noaa.gov/pub/linux/redhat/linux/updates/9/en/os/i686/glibc-2.3.2-27.9.i686wget ftp://noaa.gov/pub/linux/redhat/linux/updates/9/en/os/i686/nptl-devel-2.3.2-27.9.i686wget ftp://noaa.gov/pub/linux/redhat/linux/updates/9/en/os/i686/openssl-0.9.7a-5.i686and then did: cd /tmp rpm --force -Uhv glibc-2.3.2-27.9.i686rpm --force -Uhv nptl-devel-2.3.2-27.9.i686rpm --force -Uhv openssl-0.9.7a-5.i686and rebooted the machine just in case.
is not available on Red Hat Enterprise Linux 5, which uses Yum (Yellowdog Updater Modified).
The entire stack of tools that installs and updates software in Red Hat Enterprise Linux 5 is now based on Yum.
Note that the automatic update WILL install the latest i386 version of each package.
The packages for newer architectures need to be installed in such a way that they "overwrite" the current i386 versions.
While 99% of packages are compiled for the i386 (since they would not benefit in any substantial way from the extended instruction set), some packages are specifically compiled for Pentium or Athlon for efficiency.
