Issue Details

When I connect my PXI chassis via MXI to my computer I can't see the PXI or any of the cards in NI MAX. In Windows Device Manager for the PCI-to-PCI bridge devices I see:
Error 10: Device cannot start.


This device cannot start (code 10).

Even after I have run MXI-Express BIOS Compatibility Software the problem is still there. 


This error is shown when your device is in native PCIe mode. Because the chassis is a PXI chassis rather than a PXIe chassis the BIOS is having trouble enumerating the chassis while in this native mode. 

In order to disable PCIe native mode, use the following steps: 
  1. Open the start menu and type cmd into the search box
  2. Right-click the cmd.exe and select Run as administrator
    • ​​If you don't explicitly run cmd.exe as Administrator, you will see the error message below even if you signed into an Administrator account.
The boot configuration data store could not be opened. Access is denied.

  1. In the command window type bcdedit /set pciexpress forcedisable
  2. Reboot the machine

Additional Information

It can be determined that the machine is in native PCIe mode when one of the ports in Windows Device Manager is labelled "PCI standard PCI Express to PCI/PCI-X Bridge" as in the image below.

To revert back to native PCIe mode use the command bcdedit /set pciexpress default .
