                            Be careful when programming the chip, use verification. Leave the EC chip as is. Good luck.

                                  At 1st boot press F10 and reset bios to factory defaults, save, restart and password will go on. After that enter in bios setup and in Main tab you have "set machine unique data" and write there what it's written on the label inside the bottom cover. Or extract DMI from your bios dump:
