You will first need to register your system with the Redhat Network. If not, STOP, google "rhn_register".
Type the below commands in your shell as root:
#up2date -i -f kernel (for single processor server)
or
#up2date -i -f kernel-smp (for dual processor server)
Check to see all files exits in the "/boot" directory that "/etc/lilo.conf" is pointing to... followed by:
#lilo -v -v
...to install the boot loader, the "-v" option increases verborsity.
Look carefully for any errors before rebooting.
#shutdown -r now
Above is a shortcut of the steps to do the update. If you need a more extensive howto, then visit the Forum.
NOTE:
"lilo -R <kernel label>" sets default command line for next reboot.
see "man lilo" for information on one time boot to a particular kernel.
The lilo -R command will make it reboot only once to the new kernel. If for some reason, server does not automatically reboot... reseting it will automatically boot to the old kernel. If it comes back up fine then you can edit the "/etc/lilo.conf" and set "default=" the new kernel label.
"lilo -q" queries the boot map
