I'm not even at the point of the Mac client asking for the file yet,
so it probably doesn't matter where it is.  But, just in case the path
name is confusing the Mac I tried just "yaboot".  No luck.

I had tried these before from your previous posting (and I just tried
again).  Doesn't seem to make any difference.

I also tried all these options, and I can see them get sent with
Wireshark, but still the Mac will not initiate the TFPT request.  It
just gets and IP from dhcpd and sits there.

Do you have notes what those options are suppose to do?  Are they
suppose to fake what a OS X dhcpd server would send to trick the Mac
into booting?

Only think slightly odd in Wireshark is in the DHCPD reply I see
"Server host not not given", but other wise Next Server is set.

I see "root-path" set below, but even on the i386 boot I don't see it
being used for anything.  Do you know its function?



This was my last attempt:
