When a system board is replaced, the DMI region of the EEPROM is typically blank or contains generic test information. The DMIFIT process populates this region with the correct information for that specific computer chassis. This is critical for several reasons:
Insert the USB drive into the affected HP laptop and power it on. Immediately press the key to access the boot menu (usually F9 or Esc ). Select your USB drive as the boot device.
Because these tools interact directly with low-level motherboard firmware, they require specific environments to run safely. The DOS Bootable Drive DMIFIT tool and HPBQ138.EXE
Once Rufus completes the process, open the USB drive in Windows File Explorer. Copy HPBQ138.EXE (and any associated files from that specific DMIFIT package) directly into the root directory of the USB drive. Step 3: Boot the Target HP Computer into DOS Insert the prepared USB drive into the target HP computer.
Look for the command to commit, write, or save changes to the EEPROM (usually F10 or a specific menu choice). Reboot: Exit the utility and restart the computer. Troubleshooting Common Errors When a system board is replaced, the DMI
On systems manufactured before 2014 that require committing ME (Management Engine), 10 reboots are allowed until the MPM (Manufacturing Programming Mode) is automatically locked. On 2015 systems, 50 reboots are allowed before locking. This means you have a limited number of attempts to program the DMI information correctly before the system locks you out.
