I have it working behind me.
Most of that Wiki page is now outdated.
There is now a new branch on the linuxCNC git server which runs without rtnet with a preempt-rt patched kernel. Here is what I needed to do to make it work.
Install a recent version of Linux. I am using Lubuntu 12.04, but I think most of them should actually work. Ubuntu 12.04 Precise would be a safe choice.
Install an RT-preempt kernel. Michael has prepared someThen reboot and make sure that Linux still runs. Check that you are running the new kernel withwhich should return: 3.10.4-rt1mah #2 SMP PREEMPT RT Thu Aug 1 23:59:36 CEST 2013 i686 i686 i386 GNU/Linux
The next step is to install git, get the new code, and compile LinuxCNCThis will create a new directory, containing the code for LinuxCNC. You need to go into that repository and set up a few things.You might be told that you need to install debhelper or something during this process, just sudo apt-get install anything asked for.
The final output of checkbuilddeps will be a huge list of packages you need. I tend to copy and paste it into a sudo apt-get install line, but you can't just hit "enter" as some of the packages have two alternatives, and some specify the version, so you need to edit those out and choose one alternative where there are two (they | character means "or" to geeks).
Once the dependencies are installed, you can start to compile linuxcnc. We will be creating a run-in-place system to not break the existing installed version. To use a RIP build you need to issue a command in a terminal window, then run "linuxcnc" (or halrun, emcsh, or the others) in that same terminal window. You might have spotted it aboveThat really is dot-space-dot-slash at the beginning. If you are not in the linuxcnc-dev folder then you need the correct path to the scripts directory.
Anyway, to compile:There will be a _long_ time to wait between "make" and "sudo make setuid". It's easy to forget the final command in the interim. I often do then wonder why LinuxCNC won't work.
At this point you should have a working software system. To make the 7i80 work it needs to be plugged into the ethernet port of the pc, and the pc needs to have its IP address on the wired network port set to 192.168.1.1. W1 and W2 on the 7i80 need to be down, so that the IP address is set to 192.168.1.121. You also need to know the 7i80 MAC address.
From that point on it should look a lot like any other Mesa card, but instead ofthe HAL file needs
Obviously I don't expect you to be up and running with these instructions, it is more a case of giving you a taste of what is involved. You can do all of this as an experiment without the 7i80, then decide which card you want to purchase.

I have a 7i80, Let me see if I can make it work. This may take some time.

I think it is possible to do everything here with a GUI, but instructions like "Install Eclipse and click the icon that looks a bit like a sandwich, not not that one, the other one" would be more ambiguous.

This is partly because it is much easier to give command-line instructions on a form than GUI instructions.I haven't any experience with Linux, it looks similiar to the old dos programs on early PCs.
