After years of running, my first break down

OK I did that.

I attached the text as it was in the terminal (terminal.txt)
because there was some message that looked important.
an all.txt.

well this is weird:

insmod: error inserting '/usr/realtime-2.6.32-122-rtai/modules/linuxcnc/hm2_pci.ko': -1 Unknown symbol in module

This indicates to me that something basic is broken in the PC/LinuxCNC installation

Thanks for all of your help.

I have a solid state drive, I have heard that sometimes they get corrupted.

I will try to reinstall my current version of Linux CNC.first (assuming it is still available)
I hope the old version is still available because I tried to update to a newer version of Linux and LINUX/CNC about a year ago and the upgrade involved more problems that I was able to handle.
I would like to upgrade though, maybe I will try to build up the courage to try again.

I have a back-up hard drive so I switched to that.
Same problem.

which error?
the "unknown symbol in module" is very different from the missing 7I64 pin

The page that comes up when I tried to run LINUX CNC, I can run the other command and see what happens.

I was thinking that using the different hard drive would eliminate the linux and Linux CNC install.

Yeah, it should eliminate any file corruption issues but not PC-hardware/5I23/7I44/7I64 issues
Its still not clear to me what the real problem is since both 7I64s were detected, maybe PC/5i23

I ran both sets of commands that you told me about.

The all.txt file is empty.

I included all of the files most recently created.

That looks like the

halcmd loadrt hm2_pci config="firmware=hm2/5i23/SVSS6_8.BIT sserial_port_0=00000000"

^^^^^^^ This has to be all one line ^^^^^^^

command did not work at all

Sorry for the mistake and thanks for your patience.

Here is the correct all.txt file.
