Mesa 6i25 pc will not boot

I can not pinpoint the exact models, but it worked for me on every Dell, Lenovo, HP, and Fujitsu i have tried those, i had 2 of 6i25, one is in daily use for several months on a Dell Optiplex 9020.
Same goes for 5i25, worked for me on the above mentioned PC's.
From motherboards, it worked on a Gigabyte X570 and an Asus B550-F.
I can test on MSI B550 Gaming Gen3, that strangely has a parallel port header and 6 PCI-E slots on a year 2021 MB!

I have just thought of a possible option, could anyone who is using a 6i25 with no issues, help me with which bios and what version they are using, I can then try source another pc
 

Here is a cheap and rather UK-specific all-in-one solution.

I have one of these as my LinuxCNC development / test PC fitted with a 6i25 and a parallel port card (and it has an onboard parallel port too). It has the best latency I have ever seen (3 figures with RTAI, around 1200 with preempt-rt)

So, it definitely works with a 6i25 and it definitely has acceptable latency. But be aware that it is not a touch-screen, if that is something you need.

Hi thanks for that, I would be using a touchscreen or it would have been a good option. 

It's a completely standard motherboard inside, I guess you could harvest the parts. 
I think that the screen cover (schoolboy proof) is a bit too thick for stick-on touchscreen adaptor, there would be excessive parallax, but they do exist.

Guess my 6i25 is junk

If you want to send it to me (I think you are in the UK?) then I can try it in place of mine to be absolutely sure. 

Is the latency on the RM-ones good, at least?

Not even got that far, they will not boot full stop with the card in so not taken it any further.
 

You can run the latency test without any hardware installled. And, in fact, without installing LinuxCNC if you boot from the a USB stick. 
(It's probable that the RM-One, as a school PC, will refuse to boot from the front-panel USB sockets by default)
