Updating DMI
After replacing a system board in an HP EliteBook product, you must configure and customize the
replacement system board with notebook-specific information, such as the serial number, product name, and
number. The information is programmed to the Electrically Erasable Programmable Read-Only Memory
(EEPROM) of the system board. The DMI update process usually involves the following procedures:
1.
BIOS update—This involves updating the BIOS to the latest version or a specific version requested by the
customer.
2.
DMI update—This involves updating the system board's DMI information to match the removed system
board to support the installed hardware and software.
3.
Verification—Confirm that the system is not in MPM mode. Customers should receive locked systems
only.
Access the update menu
In the past, commercial notebooks required a special utility called WNDMIFIT (or DMIFIT) to update DMI
information after a system board replacement. With the HP Common Core BIOS, those tools are no longer
required.
When the notebook is in MPM unlock mode, the Set Machine Unique Data option appears in the Main Menu of
the HP Computer Setup utility:
Selecting this option presents the following menu, which allows the service technician to enter the required
information directly from Computer Setup.
After all of the required information is populated, the service technician is prompted to save changes and exit.
Another prompt asks the technician to lock the MPM.
