Comment 98 for bug 1065281

Logs from an installation where 50format_efi was modified with the "-s 1" option for mkdosfs. This allowed the server to drop us to a grub prompt and boot the OS by hand with a few grub commands. I'm guessing grub2 might also need some work. Possibly this patch would help?
