The full path for the Red Hat Enterprise Linux loader is \EFI\redhat\elilo.efi and it
is on the device you are accessing.
The full path for the SuSE Linux Enterprise Server loader is \efi\SuSE\elilo.efi, and

3. Use the bcfg command to manage the boot options list.
The bcfg command includes the following options for managing the boot options list:
• bcfg boot dump — Displays all items in the boot options list for the system.
• bcfg boot rm # — Removes the item number specified by # from the boot options
list.
• bcfg boot mv #a #b — Moves the item number specified by #a to the position
specified by #b in the boot options list.
• bcfg boot add # file.efi "Description" — Adds a new boot option to the position
in the boot options list specified by #. The new boot option references file.efi and is listed
with the title specified by Description.
For example, bcfg boot add 1 \EFI\redhat\elilo.efi "Red Hat
Enterprise Linux"adds a Red Hat Enterprise Linux item as the first entry in the
boot options list.
Likewise, bcfg boot add 1 \efi\SuSE\elilo.efi "SLES 9"adds a SuSE Linux
item as the first entry in the boot options list.
See the help bcfg command for details.
4. Exit the console and iLO 2 MP interfaces if you are finished using them.
