All the examples I've seen for updating bootcode assume GPT. If one has MBR
(as I do) and assuming the following basic scheme:
gpart show ada0
=3D> 63 976773105 ada0 MBR (466G)
63 976773105 1 freebsd [active] (466G)
gpart show ada0s1
=3D> 0 976773105 ada0s1 BSD (466G)
0 943218736 1 freebsd-zfs (450G)
943218736 33554369 2 freebsd-swap (16G)
would the equivalent bootcode statement be:
gpart bootcode -b /boot/pmbr -p /boot/zfsboot ada0s1
where the boot code is /boot/zfsboot (rather than /boot/gptzfsboot) and
ada0s1 is the slice on which FreeBSD is installed?
Thanks.
