Installation notes

This update is provided as an RPM package that can easily be installed onto a running system.
First, find out which kernel package to use, for example with
rpm -qf /boot/vmlinuz
Download the kernel image fitting your setup and install it with either:
  • rpm -Fvh k_deflt-2.4.19-222.x86_64.rpm for the default kernel image, or
  • rpm -Fhv k_smp-2.4.19-222.x86_64.rpm for the SMP kernel image, or
  • rpm -Fhv k_numa-2.4.19-222.x86_64.rpm for the NUMA kernel image, or
(N.B.: only install one of these kernels, not all of them.)
In case you are using lilo, please make sure that you also execute the command
lilo
after installing the update for the system to remain bootable.
Finally, reboot the system with
shutdown -r now
to load the new kernel (replace "now" with the appropriate amount of time to allow local users to cleanly log out, for example "+5" for five minutes.)
