What version of Debian were you able to get the ethernet to work? If it is Jessie, it isn't hard to install Linuxcnc on it using Preempt-Rt and Buildbot

I tried: "debian-live-8.6.0-i386-xfce-desktop" I'm happy to try some alternatives distros if necessary. Is XCFE preferred for LinuxCNC? Can you explain step-by-step how to install LinuxCNC or provide a link?

The first thing you need to do is install a Preempt-RT patched kernel (or apply the patch yourself). The last time I installed Jessie, a Preempt-RT kernel was available to install pre-compiled from Debian Backports using Synaptic. It appears to no longer be available there.

I just installed a Preemt-RT patched Kernal from the Debian archive site add the repository.
deb snapshot-sibelius.debian.org/archive/debian/20160810T050046Z/ jessie-backports main
Then close synaptic and at a command prompt type
sudo apt-get -o Acquire::Check-Valid-Until=false update
This will let you use Synaptic to install from the old snapshot archives.
Then reopen Synaptic and install
linux-headers-rt-686-pae
after that is installed install
linux-image-rt-6860-pae.
Then reboot into the new kernel, and follow the instructions for installing Linuxcnc from buildbot for the preempt-rt.

Thanks! I'm new to Linux so I don't know all the commands to comfortably make this happen. Would these instructions work?: forum.linuxcnc.org/forum/9-installing-li...ssie-and-linuxcnc2-7

Yes except for the real time kernel installation, because they are not currently available in jessie-backports. For some reason the real time patched kernels seem to appear and disappear every few months. I've heard some speculate it is because of pending version upgrades, but I don't understand why the old has to be removed so long before the new is released; (They could easily overlap for a period of time.)
