Thanks for the suggestions. I could try to see what happens with /usr/mdec/bootx64.efi and FreeBSD's /loader.efi, possibly copied to $EFI_PARTITION/EFI/boot
Also, I have an EFI and non-EFI version of grub2 compiled for FreeBSD, also want to take a look at FreeBSD's efibootmgr (in base system, I believe). I built current computers from parts, never had to deal with secure boot. Next question is whether NetBSD or FreeBSD will be more stable on UEFI boot than non-UEFI, need to try it and find out. Tom
