I've just spent some time trying out netboot capability for the
various firmware revs for Jensen. Maybe it is useful to people as
a reference. I hope to find a rev V3.5 firmware CD to try if the
V1.9 firmware BOOTPs OK. 

For now I advise people to stay at V1.8 or below. Note that D-Unix
V4.0 will complain about the DDR that is not initialised. It uses
compiled in defaults (that's at least what it looks like). I've spotted
no further ill effects of running firmware that is way to old according
to the D'Unix release notes.
