Now work boot priority Legacy first, with UEFI first loader not found. There diagnostic messages, but unfortunately, they take more than two screens and almost unreal to see even at 50fps video recording After https://svnweb.freebsd.org/base/head/sys/boot/efi/boot1/Makefile?r1=282474&r2=282727 seems to need additional changes, I corrected reloc.c to self_reloc.c but the image obtained is not loaded, though and with diagnostic messages.
