If you need the web link for the files, take a look here for the ultra small form factor version: http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=3459247&lang=en&cc=us&prodTypeId=12454&prodSeriesId=3459242&taskId=135
If you need to determine what computers in your environment have the drivers installed, you'll need some type of software inventory solution.
I have the links to the HECI drivers, thanks. I've even sat down at a machine and looked through the Device Manager but there's no listing there for HECI. I'm assuming because it's not there, I should install it, right? The same with LMS?
