red_gear,
I apologize, I couldn't quite determine the scope of your question before. I understand better now. Yes, you can communicate with the 7041 directly through the PCI bus.
You should be able to see the board in Measurement and Automation Explorer under Devices and Interfaces once you have DAQmx and LabVIEW Real-Time installed (install RT first).
Since you can't download the manual, take a look at this knowledgebase article:

Also, you can try getting the manual here from our FTP server:
