Problem solved, thank very much PCW and Tommylight !
I have "some" idea about the source of the issue, it has been some permission that was not allowing loading linuxcnc fully
When I loaded linuxcnc through EFI mode, it gave some wird results:
"cannot gain I/O privileges - forgot 'sudo make setuid'?
Note: Using POSIX non-realtime"
Here you can see that BIOS restrict something
I made a new fresh installation on disk 1 and started from the disk (not EFI mode)
No more problems and working good
At this point the 7i97 is attached to servos and doing it very well, running without error and very nice, next thing is to see how can access to the I/O...
