The HP Z420 is a nice workstation. They come in two versions where the BIOS Boot block either allows for 2011 Xeons V1 or also V2. The problem is that the "normal" BIOS can be updated using a USB-stick with an updated image. The Boot Block cannot. And it is the BootBlock that sets the difference. I have seen procedures on the net that requires a considerable effort and the use of a Raspberry (or some of this kind) and multiple wires attached to the BIOS circuit. Warnings are issued: Any mistake will brick the mobo. It is also quite time consuming. Anyone knows of a simpler way to do this update? Can it be that the circuit comes preloaded for board population?
