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.*.i586.rpm for the default kernel image, or
  • rpm -Fhv k_athlon-2.4.*.i586.rpm for the AMD Athlon optimized kernel image, or
  • rpm -Fhv k_smp-2.4.*.i586.rpm for the SMP kernel image, or
  • rpm -Fhv k_psmp-2.4.*.i586.rpm for the PSMP kernel image
Please do only install one of these kernels, not all of them.
In case you are using LILO as bootmanager, please make sure that you also execute the command
lilo
after intalling 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.)
