Re: HP BIOS unlock tool

On the other hand I did not succeed in having a reliable dump with the clamp (with or without charger, with or without capacitance on the power supply (3.3uF and 100nF wired to the shortest (very close to the chip not on the clamp))).

Does anyone have this card implantation so that I can remove this circuit....
