Pimping the mini-lathe

Unless the bios has changed (and it may have) this PC worked OK for me.
You need to edit the bios to disable any of the C7 type wait states.
Too long ago for me to remember

I basically turn off everything in the bios. All the options on the CPU, the audio, etc.

I turned off everything like you.
But when I choose the kernel with RT in the name at the grub customizer menu, PC is freeze after 1 minute.
Can you post here your uname -a

Hi,everyone
I have update version of kernel, with this 4.16.12-rt5-kona-rt, and this is the result.


All night working,no freezing.
Is that results are, good for this PC.

Sorry, but that's rather poor latency (max jitter)

As an experiment, try running the LinuxCNC live image in "Live" mode (ie, leave your hard drive and current installer untouched) to see what that kernel gives you for latency.

You could also try the RTAI kernel.

I think the latency test needs to be redone without the base thread. For a Mesa Ethernet card which is all this USFF PC can run, I think the servo thread latency is OK
