PC won't power up with PXI chassis connected

[markshancock]

I have a rack mount NI PC - RMC-8356 with a PCIe-8398 running Windows 10 with NI PXI Platform Services v18 installed

This boots fine!

I also have a NI PXIe-1085 PXI rack with a PXIe-8398 installed in slot 1

If I plug the cables from the PXIe-1085 into the PCIe-1085, the system will no longer boot (not even to the firmware).

I have double-triple confirmed that the cables are plugged in correctly and firmly.

The behavior is very consistent. 

What do I do next?

I have heard some PCs have issues enumerating the PXI boot info.  Is this an issue for the NI PC.

Hi, have you tried updating the firmware?

It is a NI PC and NI confirmed it is running the correct firmware.
I am now able to boot (though nothing has changes); but, I still can't talk to the PXI rack.

The good news is that NI has been able to reproduce some of the behavior and they are investigating.
Once I have a resolution, I will post it here.

The problem was caused by issues enumerating the PXI boot info - see http://www.ni.com/tutorial/53268/en/

It was resolved by installing NI MXI-Express BIOS Compatibility Software 18.0

Important Note: You MUST install the 18.0 or newer version it you are using WIndows 10 and/or UEFI/GPT

Previous versions can corrupt your Hard Drive and brick your PC.  See https://forums.ni.com/t5/PXI/MXI-Express-BIOS-Compatibility-Software-1-5-Bricked-my-BIOS/td-p/389973...
