Hello,
I'm trying to net boot a Sparc Workstation using a MacOSX machine as 
it's server. The ultimate goal is to install NetBSD on the Sparc. While 
the problems I'm having, may possibly considered a Darwin issue, I've 
already found much more documentation towards setting up the rarpd 
server on netbsd.org than anywhere else. So I'm hoping you'll be able to 
help. The following is the documentation I've already consulted:
http://www.netbsd.org/Documentation/network/netboot/rarp.html#macosx

My Sparc has been set to 'boot net-tpe' and seems to be functioning 
properly from it's end. I get a continuous loop of "Timeout waiting for 
ARP/RARP packet" from it.

However, on my MacOSX box, after I initiate the  '/usr/sbin/rarpd -a -d' 
command, I get a line that states 'en0' and my Mac's mac 
address...restates that again on a second line, then nothing. Both of 
these are hooked up to the same 5 port Netgear hub.

Any thoughts or suggestions for getting this to work, or troubleshooting 
at a lower level would be greatly appreciated.
