Odd observation... PC will only run 32bit RTAI and not 64Bit??

Tommylight, I have tried using mint 19.1,2,3 with the precompiled files in www.linuxcnc.org/temp . they work fine on the t3500 and don't on the 780. I haven't been able to compile the latest RTAI kernal for 32 bit. That is as far as I can tell the only differences between them. I am using the same drive between both machines and have used the same settings in both BIOS's. It is completely baffling to me as to why one pc works and the other one doesn't(with the same drive). Normally I would just swap the pc's but I can't fit the t3500 in place of the 780 SFF.

This sounds like the same thing as is mentioned in this thread

I have no idea why this happens to random (but few) users. And I can assure that I did follow the instructions exactly, but this happened on only one computer.

akb1212, I don't understand how this relates to my particular issue...? I don't believe that I get that error. When I run a HDD in the 780 that I have verified working in the T3500(ie the latency test works and I can open up Axis and jog things around without errors) the OS boots up fine but the latency test doesn't work and linuxcnc tells me that there is a problem with the configuration. BUT the same config works in the t3500 so I am at a loss.

It was tomylights config that ended up at 900 MB that was similar, not yours (hence why I quoted his post). What happens in some (random?) hardware is that it puts on error reporting or something that makes the image 10 times a large as normal.

My point is that there are some hardware that ends up making differences to the configs that makes a big difference. In my (and tomylights) case this ended up with an image that was so bit it's impossible to start it!

So on a general note, (exactly!) the same procedure ends up with different configs with different hardware.

Ah I see. Any words of advice on troubleshooting this. I end up with the same problem if I setup from scratch on the 780 no swapping period. But I did clone the drive and the cloned drive works in the t3500....... really limited error reported even when launching the config through command line.
