As far as I understand it, real s390x hardware has no concept of booting from ISO and do not support el torito. qemu/kvm on the other hand have implemented support for using el torito boot on s390x, and certainly it does seem than many distributions (Ubuntu, SUSE, Fedora for example) do include el torito boot info on s390x media. -- Len Sorensen
