Hey, I just bought a ThinkPad x200. Turned out there was a supervisor password on the BIOS (including the TCPA pass-phrase encryption). I tried different things: shorting out SDA & SCL pins, taking out the CMOS battery, none of them worked. Thanks to AllService.ro I was able to dump a binary file from my BIOS. I build a hardware interface to connect to the BIOS chip (the SDA, SCL & GND pin). Unfortunately, due to the TCPA encryption, I wasn't able to find the supervisor password in the binary file (using IBMPass). I have found a way to edit out the supervisor password from the binary file (address 0x338 to 0x347). I replaced it all with zero's. I am thinking about cooking back the edited binary file, but I am scared that the checksum will cause problems. Has there anyone been in the same situation, if yes, can you supply me with more information to help me solve this problem? (PS. The laptop was not stolen, it was company owned before)
