Unfortunately I don't. What I ran into was this - the G4 would get an  
IP via DHCP, load the loader but the loader wouldn't find the NFS  
server to load the kernel from even though it's IP is identical to  
the DHCP server. What helped was to add 'next-server  
192.168.0.whatever;'
We certainly needed that in 4.0, I never tried it with 3.0 but I  
suspect we need it there as well.

Hmm, my dhcpd.conf for a sparc64 box uses this:
  host becherovka {
    hardware ethernet 08:00:20:aa:bb:cc;
    filename "netbsd.becherovka";
    fixed-address 192.168.0.18;
    server-name "talisker";
    option root-path "/home/sparc64";
    next-server talisker;
  }
I'm pretty sure that's derived from what I used to boot my G4.

Does your G4 do any nfs talk at all? I remember having to fiddle  
around with those server IP options.

have fun
Michael
