There isn't even a indication that the bootblocks get loaded onto the 
600au. If the boot blocks would be transferred, there should be some 
traffic to and from the tftp port. But I haven't found anything going on 

The other things that makes me wonder is, that the same 600au has been 
installed a 2.0.2 via net boot. But I used NetBSD/alpha on a 3000/800 as 
a dhcp server. I couldn't get the 600au to boot off linux/i386 as the 
dhcp server. It seems to me, that there is some kind of magic in the 
BOOTREPLY generated from the dhcp server (or the underlying tcp stack?) 
that differs between NetBSD and linux.

I'd like to get this working due to the hassle I would have if I have to 
use some other approach to install NetBSD on the 600au. Last but not 
least I'm curious to get this problem solved.
