Sorry, I gave you the wrong file for the specific ID you posted.

This one should work.

https://ftp.hp.com/pub/softpaq/sp72001-72500/sp72085.exe 

Here is a partial copy and paste of the driver setup information file which shows driver support for the hardware ID you posted.

Go to the device manager.

Click on the PCI Encryption/Decryption Controller needing the driver.

Click on the driver tab.  Click on Update driver.

Select the 'Browse my computer for drivers' option and browse to the driver folder that was created when you ran the file.

That folder will be located in C:\SWSetup\sp72085.

Make sure that the Include Subfolders box is checked, and the driver should install.
