  You're right.  Apologies for various lacks of information.

  I'm using rarp, tftp, and dhcp.  Or at least, that's what I mean to be doing. 
 rarp is working, and tftp seems to be working.  I'm not 100% sure how the 
sparc knows who to contact for the NFS root, though.  That's likely my problem. 
 How is that normally done?

  This host doesn't have a bootparams file, and as I've done this sort of 
booting from this server before, I assume that I wasn't using rpc.bootparamd.  
My DHCP server has the following block in it, which I believe is what I was 
using to specify this:

# A diskless boot host
group {
  # server to NFS from, and path to mount as root...
  next-server 206.138.151.36;
  host diskless-sparc64 {
#    hardware ethernet 08:00:20:a1:8b:f8;
    hardware ethernet 00:03:ba:05:e4:7a;
    fixed-address 206.138.151.49;
    option root-path "/export/sparc64/nfsroot";
  }
}

  The sparc boot, which I also should've included in my earlier email, shows:

Executing last command: boot net
