Help understanding dell drivers

@acenyc  Unless you're building and deploying custom images because you're provisioning a lot of these systems, you don't need those driver packs.  But if you're curious anyway, the former is all of the drivers required for this system all packaged in "raw INF" format, i.e. not within installers as is often the case for drivers meant to be installed manually by individual users so they can step through a wizard.  The "raw INF" format allows them to be loaded into the database of a system image deployment solution like Microsoft SCCM.  In environments where SCCM is available, you can use it to (among many other things) install your corporate Windows image, which would contain various customizations and applications appropriate to your organization.  During that process, SCCM would check the model of the system the image was being pushed onto and include the necessary drivers for that particular system.  In order to do that, it needs to HAVE those drivers in its database.  The driver pack that Dell offers allows SCCM admins to quickly get an entire driver set for that system.

The WinPE driver pack contains the only the drivers that are necessary to even start the image process, not everything required to actually run full Windows.  WinPE stands for Windows Preinstallation Environment.  It is essentially a stripped down version of Windows containing just enough functionality to boot a system and install real Windows, as well as perform some recovery tasks.  Windows Setup actually runs on WinPE.  So the WinPE driver pack would include drivers for devices like network adapters, since obviously if you're going to download your corporate image from a server somewhere, you need your network adapter working even in this "mini OS".  The way that's achieved is by having customized "boot media" that contains the application necessary to start downloading that image, and of course any needed drivers.  The WinPE driver pack again gives SCCM admins all the drivers they need in order to get a given system model working well enough in WinPE, which they can bake into the "boot media" that they use for this purpose.
