Comment # 14 on bug 955493 from boo35 boo35

I'd set

    efibootmgr -c -d /dev/sdg -p 2 -l \\EFI\\opensuse\\xen-4.6.0_02-397.efi -L
OpenSuse-Xen
    efibootmgr -c -d /dev/sdg -p 2 -l \\EFI\\XEN\\xen.efi -L Custom-Xen

    efibootmgr
        BootOrder: 0001,0000
        Boot0000* OpenSuse-Xen
        Boot0001* Custom-Xen

    efibootmgr -o 0,1

    efibootmgr
        BootOrder: 0000,0001
        Boot0000* OpenSuse-Xen
        Boot0001* Custom-Xen

and, checking BIOS settings on startup, can verify/select those items in the
available EFI direct-overrides list.

However, after reboot,

    efibootmgr -v
        (empty)
