Thanks for the fast reply. Ok, I've ignored those items and moved on to the Xconfig. Sadly, bumps in the road here too. You wrote in bold letters :
"CAUTION: You MUST at the minimum select "Fully Preemptable Kernel" in the "Processor Types and Features" section"

Well, I do not see an option for a Fully Preemtable Kernel in the processor Types and Features section.
Perhaps it is not available due to my specific hardware ? Any ideas ?

I had this problem to, There is a non graphical version of this command that does let you get to the settings. I don't really understand why , but sometime xconfig showed what I wanted, other times it didn't

I think I used make menuconfig

On the xconfig there is a search feature, use it to search for preemptable and it will show it selected, just click on it.

using "make menuconfig" instead of "make xconfig" worked great. Thankyou. It was a bit hard to see that there are subdirectories, but once that was evident I found the preemptive kernel option and check marked it.
and that link was informative too. Much appreciated. Was getting a little frustrated already !

Until the next time :-)

Cheers,

Jake

It appears, to check which kernel is installed, one should use the command :

uname -a

Ok, Mission accomplished. Many thanks to cncnoob1979 ( and rodw ) for the instructions, as it wouldn't have been possible without your guidelines. Being a true linux "noob" I'll try to document and share which items I had issues with for other true beginners to gain from. I would not have been able to finish without using my "phone a friend" lifeline... a few times :-)

For instance, I was using the apt-get update command and didn't realize I needed to add the sudo command. Thats truly a beginner mistake, eh !. Lesson learned, when an error comes back " permission denied " its probably because I'm not logged in with superuser privileges. Solution, get that permission by using the sudo command !

Ok, now its onto the next task.... getting linuxcnc to talk to the Mesa 7i76E.

I don't want to hijack the thread, but now it appears I need to install drivers for the Mesa 7i76E and then I'm told to use pncconf to configure it.

You do not need drivers or anything, you need the second tutorial from this thread, after that you can run pcconfig to configure the card.
