Jedi_Admin,   I believe the download needed can be found here for Windows 2008, 2012, and 2016, or here for Windows 2019, depending on whichever you have.     Let me know if this helps.    
We have new power edge R740 servers, these new servers have Fiber Channel cards installed and use Qlogic drivers. We also have a Windows image that works with our other Dell servers including our Dell power edge R740 servers that do not have Fiber channel cards and use Broadcom drivers. During the Network configuration within our build iso it does not detect the NIC's on the Dell power edge R740 with fiber channel servers, The QLogic drivers are present within the build process same with the Broadcom drivers. Any thoughts on how I can get this fixed so I can push our image to the server from the network? Does the FC need to be disabled before we do the OS push? If so what is the process to accomplish this?
