This process is explained in detail in the SMC_Creation_9_2015.pdf included with this training. If the MPM is locked, you will need to escalate to 2LS and provide the SN and UUID to get an SMC Blob, which will unlock the system. This is the state of the system board when it is returned to the customer. MPM locked DMI programming is complete on these boards.

If the board is not programmed completely (that is there is missing DMI information) within the 35 boot cycles after the Panic Screen is first shown, the MPM is automatically disabled and the board is locked, but the Panic Screen is still displayed showing which information is not programmed.Īn SMC key must be obtained to unlock the board and complete programming is auto locking occurs. The boards remain in this state for 35 boot cycles, or until they are programmed and locked. MPM unlocked This is the state the replacement boards are in. The system board can be in one of three states relative to DMI programming. Once every field has been entered, MPM will be automatically locked.Ĭonfidential Copyright 2016 Hewlett-Packard Development Company, L.P. This screen is displayed on very boot cycle until the DMI information is programmed completely. Other BIOS features remain unchanged and the system can boot to the OS. If the service technician programs DMI information incompletely and the locks MPM, a warning screen displays that shows which DMI fields require programming. When the product is in this mode, the Set Machine Unique Data option appears in the HP Setup Utility Main screen, which allows DMI information to be entered directly into the utility: In this state, the board is unlocked and DMI can be programmed. HP Common Core BIOS programming steps HP Commercial Desktops and workstation with the HP Common Core BIOS use the HP Computer Setup utility to program DMI.Īfter system board replacement, the board should be in Manufacturers Programming Mode (MPM). HP Desktop DMI Programming Step-by-Step GuideĬonfidential Copyright 2016 Hewlett-Packard Development Company, L.P. Note: For BIOS versions 5 and earlier, you need to update the DMI information using the legacy DMI flash utilities.Ĭontents Desktop and workstation MPM states.

The following sections list the steps for the Common Core BIOS, BIOS versions 6, and 7 and later. As the service engineer, you first need to determine which BIOS version the desktop PC is using before attempting to update the DMI information.Īfter you have determined the BIOS version, you should implement the correct steps to program the DMI information. The method for updating the DMI fields depends on the BIOS version number. In HP desktops and workstations, the DMI information is programmed using the HP Setup utility.
