Simply cd to src/sys/boot and do 'make clean && make && make DESTDIR=3D/altroot', the latter only if you don't want to overwrite curdev's /boot/ files. For loader.efi only, it's enough to do 'make clean && make' in the following directories: src/sys/boot/ficl src/sys/boot/efi src/sys/boot/amd64/efi =46rom amd64/efi you can 'make install' to just copy loader.efi (or copy manually from obj/$src/sys/boot/amd64/efi/loader.efi) > I realized that building loader.efi with any kind of optimization beyon= d debugging- or > close-to-debugging level ends up in an unloadable loader.efi on Haswell= CPUs (IvyBridge > and C2D seem to be unaffected).
