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

Thank you Wayne, but my DHCP is handled by the FOG server.
It’s all one unit.
Would the same theory work?
Modify the local DHCP server? How would I do that?
Thanks

Hello everyone.
I think I may have the same problem here with the new Lenovo Yogo 12 and the realtek 8153 USB-Ethernet NIC.
I get to
iPXE initialising devices…
and it hags there.
In reading this post, it seems that I need to update my undionly.kpxe to undionly.kkpxe.
My problem is I don’t even know what that means.
I am VERY VERY green to linux command line manipulation.
In fact, I was only able to get this working last year in the first place thanks to the wonderful patience and support from this community and Tom Elliott.
But I have been using this server flawlessly for that entire year.
I was able to update from 1.0.1 to 1.2.0 and then go do subversion to the newest. All of that seemed to go fine.
Can anyone please help with directions on how to change the .kpxe to .kkpxe?
Thanks in advance.

Oh, I have Ubuntu 14.04 LTS 64 bit OS
