OS install notes:

There's an updated storage driver (IRST F6) to include PCIE support. ( The one you have to install for Windows to see the drive during installation ) :

Intel 14.8

Dell 14.5

Dell 15.2

Samsung Driver

Obtaining an ISO image:

For some systems you can obtain Dell operating system images through Dell Hosted image

Note: not all systems and service tags will have an image available for download.

Note: Even though Dell Hosted Images have USB3 drivers slip streamed in, they may not include the IRST driver at this time. ( some may know this at the F6 driver ). As a result you may need to install the IRST driver manually during the Windows install process.

Dell is currently working to add the IRST driver to the Dell Hosted Images. No ETA on when this will happen at this time.
