--- Comment #15 from Naomichi Nonaka <nao@enuenu.org> ---
OK, I found my mistake.

I had written "set boot_disk_unit=3D0" in /boot/loader.conf. after removing=
 that
line. rev2 boot1 can boot to external drive.

# I wrote that line in very early stage of my testing and forgot that.

for boot drive choise, I found 10.2R boot1.efi boot to external drive. So I
assume Mr. ISIZUKA had installed 10.2R to internal drive, and when upgraded=
 to
10.3R, boot1.efi had not upgraded to 10.3R.

You can check size of boot1.efi.=20
 10.2R is about 33K, 10.3R is about 74K, and rev2 is about 82K.

Summary:
 when both internal drive and external drive have bootable partition.
*10.2R boot1.efi
 -> autoboot to external drive

*10.3R boot1.efi
 -> autoboot to internal drive

*rev2 boot1.efi
 -> show partition list. can boot to either internal or external by keyin
    timeout boot to internal

--=20
