Can anyone see something I'm doing wrong here?  It seems that my sun3 
isn't getting all the bootparams that it needs.

I see this on my sun3:
>b le () -s
Boot: le(0,0,0) -s
Using IP Address 170.215.197.13 = AAD7C50D
Booting from tftp server at 170.215.197.5 = AAD7C505
Downloaded 15360 bytes from tftp server.

My /etc/bootparams file contains just 1 line for now:
felix.telenova.com root=/usr/local/sun3-netbsd 
(I removed swap and dump for simplicity, will fix later).

I have everything exported fine via NFS.. 

Thanks for your time,
