Hi, Try these links 7.2.20 7.4.8 7.6.15 7.8.0 7.10.61 7.12.17  
Hello, I'm new to the forums. I'm trying to upgrade drivers and firmware for the Broadcom network adapters in a PowerEdge R820 running vSphere ESXi 6. I have no problem finding the drivers as they are provided by VMware. Regarding the firmware, it is currently firmware version 7.2, and I want to go to version 7.12, but looking at Dell Support page I cannot find the complete upgrade path (7.12 release notes recommend having 7.5.8 installed, but I cannot find any link to that version, or any previous version). Can you please help me find all the upgrade packages in chronological order from 2012 up to now?  Thanks,Arismonty BeatoDominican Republic
