I'm now aware that the 7i96 complicates the issue, but I didn't do enough research before I bought the thing.

The 7i96 is a very good board. I now have used several of them. You have to have the correct version of linuxcnc for any of the Ethernet cards.

master is fine, 2.8 and master is almost the same.
pncconf in master will configure the 7i96

When I follow the instructions on the buildbot page for upgrading to 2.8, I get to the final step

That seems to indicate that you don't have the repositories set correctly.
Open Synaptic Package Manager, Search for linuxcnc and remove it if installed.
Go to Settings - Repositories and make sure the only active entries for linuxcnc are:

deb     http://buildbot.linuxcnc.org/ stretch 2.8-rtpreempt
deb-src http://buildbot.linuxcnc.org/ stretch 2.8-rtpreempt

If you made any changes then click Reload to update the package information.
Search for linuxcnc and it should find linuxcnc-uspace, that is the one to install or from terminal you could enter:

sudo apt-get install linuxcnc-uspace

It may be wothwhile before you do all this to open a terminal and enter:

uname -a

and make sure there is "PREEMPT RT" somewhere in the reply to confirm you have an appropriate kernel.

I ran

uname -a

and got:

Linux debian 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc i686 GNU/Linux

Running

sudo apt-get install linuxcnc-uspace

after updating the sources in the Synaptic Package Manager gives me the following output:

danny@debian:~$ sudo apt-get install linuxcnc-uspace

Yes, plenty.....
First, wrong kernel, and from that i assume you are running the Wheezy version.
You need the Stretch Preempt-rt version from the download page.

www.linuxcnc.org/testing-stretch-rtpreem...-uspace-i386-r13.iso

Then upgrade Linuxcnc to 2.8 or master (2.9) as Andy and others have mentioned above.

That is a RTAI kernel, not PREEMPT RT. That is no good for ethernet Mesa cards.

I think you would be best served with a new clean install from a stretch ISO from here

This is what happens when I'm left to my own devices...

I could have sworn I had the right one, but I'll download fresh, flash it, and install and report back.

Thanks everyone for chiming in so far!

HEYO! Used the correct iso (which I had downloaded previously but must have mixed it up with another iso) in addition to following phillc54's instructions. I'm able to confirm I'm running 2.8!

Thanks for your help!

Now on to configuring the Mesa 7196.

That is good, you can use Pncconf for a 7i96

Does anyone know where there is a good tutorial for configuring using Pncconf for a 7i96? I ran through the config process and only set a few of the options and got the following error message:

PNCconf encountered an error.  The following information may be useful in troubleshooting:

LinuxCNC Version:  UNAVAILABLE
