We have as a institution a lot of Fujitsu hardware her - from larger servers down to Fujitsu ESPRIMO Q956. The latter one is the first (and so far the only) piece of hardware I found incapable of booting off UEFI within the past 5 years. If the "standard" for removeable devices is to boot from /efi/boot/bootx64.efi, than I'd guess it is good luck for FreeBSD that the firmware vendors did fallback to such a mechanism. GRUB/Linux seem to install by default their bootloader into /efi/something/ I'll check on Debian, Suse and CentOS so far soon, the latter probably will, since its the "free" RedHat). Anyway, apart from any criticism, I'm glad to have the tools to make things work without using alien help (outside FreeBSD's world!). That is a thank you towards the developers.
