We received a batch of Optiplex 3020's yesterday and I'm working on getting all the drivers ready to use MDT to image.  For the most part, the drivers I got worked great.  What I usually do though after I image a machine is check the device manager for components on the machine I imaged vs the one that is the OEM image on it to see what I missed.  When I look at my machine, it is missing entries for "ATA Channel 0" and "ATA Channel 5" which my OEM imaged machine has. The hardware ID lists as Intel-8c02, which appears to identify as Intel 8 series C220 series SATA AHCI controller.  However, I do have a listing for that device on my imaged machine, so I'm trying to figure out what I'm missing.  Here is a screenshot indicating what is present on the OEM and missing on my MDT image.
