1. Access the EFI Shell.
From the system console, choose EFI Shell from the EFI Boot Manager menu.
2. Access the EFI System Partition for the SuSE Linux Enterprise Server boot device.
To list the file systems that are known and mapped, use the map EFI Shell command (fs0,
fs1, and so on).
To choose a file system to use, enter its mapped name followed by a colon (:). For example,
to operate with the boot device that is mapped as fs3, enter fs3: at the EFI Shell prompt.
3. To launch the ELILO.EFI loader, enter ELILO at the EFI Shell command prompt.
If needed, you can specify the loader’s full path by entering \efi\SuSE\elilo at the EFI
Shell command prompt.
4. Allow the ELILO.EFI loader to proceed with booting the SuSE Linux kernel.
By default, the ELILO.EFI loader boots the kernel image and options specified by the
default item in the elilo.conf file.
To interact with the ELILO.EFI loader, interrupt the boot process (for example, enter a
space) at the ELILO boot prompt. To exit the loader use the exit command.
