      Have you recorded the original file yet? That helps determine where the error arose.

            There are 3 bios versions on this device. You can use another device's bios if it's the same bios, but please delete the device's DMI first.

              use this in hp elitebook 840 g8 for any error in bios no display etc. no need rebuild no need clean me no need DMI DATA.
              it auto recovers DMI via the installed SSD. i tested it.100%

                      I don't know where to find the necessary files to reset the bios password of my HP Elitebook 840 G8 laptop. As far as I have researched, 32MB and 16MB files are required. Can you describe how I can obtain these files?
