Hi dhjaffe, You can install both/all the chipset drivers available for your service tag. There is no harm in it. Also below is the sequence in which the drivers should ideally be installed.   Hope this helps
I am trying to wipe clean my Latitude E6500 & reinstall Windows Vista Home Edition. I have managed to install Vista but am stuck at the driver installation part. Everything I have read says I need to install the chipset drivers first. When I plug in my Service Tag number on the Drivers & Downloads page at the Dell Support website, there are 2 recommended drivers for the chipset - Intel AMT HECI, v.4.2.30.1040 PV, A03 & Intel AMT SOL/ LMS, v.4.2.30.1040 PV, A03. How do I know which one to use? 
Clean Reinstallation of Windows Vista on a Latitude E6500 - which drivers?
