Hi, I'm trying to netboot my macppc 9500/200 via mc0 and having few problems with that... it
looks like it's all due to mc0 drivers which Tim and others tried to sort out since last year
(even earlier than that I guess) my opinion things have improved cause now when I ping my macppc
host I'm getting 2 replys and 2 timeouts and again 2 replys and 2 timeouts...

and here it stuck I'm trying to do tcpdump from the server (192.168.100.200) but can't see no
activity from 192.168.100.254 or macppc.clapton.net which is really the same.
My question is- is it possible to somehow get kernel loaded via mc0 and all the rest via vr0 by
changing 
boot device: mc0
root on mc0
to
boot device: vr0
root on vr0
I'm not sure if that would fix the problem, but I cant really see no other reasons why it
shouldn't work, cause root path which is sent by dhcpd which is /var/export/macppc/root is right
and kernel gets loaded aswell. I've checked nfsstat, but couldnt understand much, if somebody had
similar problem please share your experience and how you've dealt with it.
