Forgotten tools from HP
#1
I have sent my OMEN 16 gaming laptop to HP.

They forgot to delete the hard disk including the tools.
Among other things, the following tools were included, in particular to unlock the BIOS:
  • HP Bios Configuration Utility v. 4.0.15.1

Locking or unlocking the BIOS is controlled by the text file mpmlock.txt, in which an asterisk is placed in front of the entry:
Quote:English
Manufacturing Programming Mode
*Lock 
Unlock

After executing, following Logfile will created:

However, I don't want to simply upload these tools here, as they could play a decisive role in BIOS cracking.

HP BCU is not a classified thing. Also, it's useless in bios cracking. The utility can lock MPM mode, but not unlock it.

But when i select unlock, the option will be written to the bios.

But i dont know, what these do.

¿Even tho in the log it is written Settings processed: 1, errors: 0, warnings: 1, skipped: 0, succeeded: 0 ?

MPM unlock disables protection of variables. Thats it.
