After some teaking, my Mac mini boot into NetBSD, but I can not get it 
to auto-boot.

If I set
     setenv boot-command boot
     setenv auto-boot? true
     reset-all
the display never gets a signal. After a few seconds, the power-light 
turns more intensive, but that's all. No boot.

If I run
     setenv auto-boot? false
     reset-all
and then
     boot
NetBSD comes up fine.

What part am I missing here?

Thanks in advance.
