BIOS Hacking
Using the Bus Pirate I have been successful in recovering several HP ProBook laptops that have BIOS Administrator passwords set. Below is a rough outline of the process.
- Gain physical access to the BIOS chip and identify the manufacturer and model number of the IC. Mine was a 25L6406E, yours may not be.
- Obtain a datasheet for your particular IC and determine the pinout for all the necessary pins required for flashing.
I hope to start a small library of BIOS binaries for the models I have recovered and the procedure used to recover a locked system.
HP ProBook & EliteBook
