Configuring SMI ... file not found? was created by Mick
I am trying to follow the SMI modification guide as posted on the Wiki. I can't find "rtapi.conf" file. I can get to /usr/local/etc but no farther.
My installation was from the new CD and everything went smooth. I am still trying to improve my latency numbers and want to do the SMI mod. but the Wiki instructions don't work for me.
Has anyone had success following the Wiki?

/etc/emc2/rtapi.conf does not exist in my install?

Do you have run-in-place installation?
find / -name rtapi.conf
Might be instructive. I found I had three due to a rather complex installation history.
If you do have a Run-in-place system you will find that every time you recompile then your rtapi.conf gets overwritten from the rtapi,in template file. This is annoying.

Did you try...
Open a terminal then type
sudo gedit
Then browse to find the file?

OK sorry, It is a Linux newbe problem. I now have the "sudo edit" GUI on my desktop and have opened "rtapi.conf"
The first line reads:
# DO NOT EDIT THIS FILE !
The wili does not talk about renaming the file? Should I just make a backup, then edit?
I am a 68 year old retired EE who spent 40+ years in machine controls so I may be able to contribute in a year or so. LOL

It is always a good idea to make a backup file. You can just save it with a new name then edit the original, or save it somewhere else before editing it. Be sure to follow the steps carefully. Remember linux is case sensitive.
Glad to have you onboard. It only gets easier as you go.
