Installation guide

If you do not know the names of the installed kernels, you can view the /boot/efi/elilo.conf file
in EFI with the following instructions:
1. At the Shell> prompt, change devices to the system partition (mounted as /boot/efi in
Linux). For example, if fs0 is the system boot partition, type fs0: at the EFI Shell prompt.
2. Type ls at the fs0:\> to make sure you are in the correct partition.
3. Then type:
Shell> type elilo.conf
This command displays the contents of the configuration file. Each stanza contains a line
beginning with label followed by a label name for that kernel. The label name is what you
type after elilo to boot the different kernels.
