The MinnowBoard has both 32-bit and 64-bit UEFI. My Turbot came with
64-bit UEFI, and the FreeBSD amd64 UEFI install image works fine with
it. This is an Atom E3826 board.

If any existing 32-bit Linux UEFI loader could be made to work with
FreeBSD (possibly chainloading?), that would be better than nothing. I
would like to have the opposite method also, having a 64-bit UEFI boot a
32-bit FreeBSD. (Why? So my run-on-anything 32-bit FreeBSD image could
still work on any UEFI system.)
