If you have two kernels compiled, then you put the bzImage files in /boot directory named, say, linuz-2.4.18 and linuz-2.4.20. Then edit /etc/lilo.conf and add the following: image=/boot/linuz-2.4.18 label=linux18 root=/dev/hda1 (or check where your root filesystem is) read-only image=/boot/linuz-2.4.20 label=linux20 root=/dev/hda1 (again) read-only Then just say "lilo" in the command line. Reboot your machine and - voila - ou can choose what kernel to boot. Kernel modules are saved in /lib/modules/2.4.18 and /lib/modules/2.4.20 for each of your kernels separately. The proper modules are loaded automatically depending on the current running kernel. Good luck! On Saturday 21 June 2003 20:52, Earl R. Lapus wrote: > Hi guys...
