You don't even need Jumpstart - I've upgraded various Ultras just by making
the update accessible via tftp and booting it. Weirdly enough, I've never
got it to work with an U2 but various U1s, U5/10s and U60s have worked
fine. I always get "Fast Data Access MMU miss" when network booting the
update on an U2, but the same update works fine when booting from local
disk. Odd.
