Ok, After some more googling, I was able to find how to change to .kkpxe.
I did this:
sudo gedit /etc/dhcp/dhcp.conf
and changed it in there
after that I stopped and started the dhcp service.
That certainly helped becuase now I get past the “initialising devices” hang-up.
However, now it goes just a little farther and reboots.
the last thing in the screen I see is
init.xz…<OK>
then it reboots.
Can anyone point where to go next?
any key words I can google/search?
Thanks
