We have a new H8DME-2 PCB REV 2.01A motherboard. We installed Shanghai CPU and the system does not POST. We then used older processors then flash the BIOS and now the system works fine with Shanghai processors. We have one PCB REV 1.2 and three REV 2.01 motherboards. Do they all support Shanghai processors by update the BIOS or is only the PCB REV 2.01A motherboards compatible with this processor?
