Hello,
I see that you have tried more than a few options. I noticed that you stated there are two PCI devices in the PC. Does the NI PCU Device work when in slot 1 and when the other card is not present? It might be that the PCI bus is only allowing one device to be seen at a time due to the BIOS. I understand that you have already done some troubleshooting with the BIOS. Did you enable PC Bus Mastering or try to correct a Resource Conflict with Other Hardware or both? The two options are described below in the linked Knowledge Base (KB). If you have already seen and tried this KB, please confirm.
Please also glance at the two additional KBs that are linked. Some additional questions I have are listed below.
Is there a PCI bridge in this computer?
What version of DAQmx and MAX are installed on this computer?

Hi All-
You might also consider this power supply requirement of M Series, especially considering that this is an industrial computer and those types of machines are somewhat notorious for not supplying the full gamut of +-12V, 5V, and 3.3V supplies required of the PCI bus. The symptom for M Series if any of those supplies is not present would be non-detection of the M Series device by the system.

Dear Samanthan and Tom,
We have rechecked again our PCI card and follow your advice.
Finally our industrial PC can detect the PCI and it works well.
The problem is about the power supply of the PC.
Our industrial PC does not support the +3.3 volt.
After we changed the power supply, the PCI works well.
Thank you very much for your helps and advices. We really appreciate that
Happy new year guys....^_^
warm regards,
