PCI Data acquisition and signal processing controller - latitude 5420

I'm also looking for this driver.  I was able to get most from the driver pack or from the driver download page for the 5420.  I even looked on the intel site but did not have any luck.

I am facing the same issue and researching for the solution . hopefully we will find the right driver .
