Vherrlein,   You won't be able to walk the iDrac back that far, what you would have to do is walk the BIOS back up to current, as you can't just update to the current version from that far back without bricking the motherboard. So you would need to walk the BIOS up without skipping more than 2 or 3 at a time, or anything marked Urgent.   Also, if you have access to the iDrac web interface, I would suggest exporting the iDrac license in case there is any issue then you have it available to restore.      
Dear Community, I'm facing some issues with one of my refurbished R720. In addition, the overall system is slow compared to the other R720 in stock: Server setup with minimal requirements to identify what going on: Someone else had the same issue or any idea on these issues before ordering another MB ? Thank you in advance.
