I am trying to get my SS1 to boot Netbsd off the net.  So far, I got it 
to tftp the boot program, to successfully complete the bootparam whoami 
and getfile for the root system.  At this point I get:

root addr=198.94.9.200 path=/local/sparc
Can't open network device 'le(0,0,0)'
open: netbsd: Unknown error: code -1
device[le(0,0,0)]:

If I follow the invitation to retry the error number changes to 23.

The boot host is running the PC version of netbsd 1.1.  It is the RARP 
server, the bootparams server, the tftp server, and the NFS server.

Previously I had used Freebsd for the RARP and bootparams, and HP-UX for 
the NFS, but the sparc would halt telling me it was unable to mount the 
swapfile.  Since I got farther with this setup than I am getting with the 
Netbsd one, I can only assume there is some configuration error on my 
part, rather than a hardware fault.

Any ideas?
