I have a USB thumb drive that was configured using the Intel AMT Configuration Utility. An Optiplex 9020 will automatically boot from this device, and apply the AMT configuration. We are replacing the 9020's with Optiplex 7050's, and these machines will not boot from the same thumb drive. The AMT/VPRO number inside the 7050's case lid is "1", showing that we did purchase these machines with AMT/VPRO enabled. I'm guessing there must be a BIOS settings that allows this to happen, but I have no idea what that setting might be. Any help with this will be greatly appreciated.
