#RESET BIOS PASSWORD LENOVO THINKPAD CODE#

Suddenly, the seller on eBay found the message feature and wrote to me, saying I got them in trouble. Turned out one of their guys was selling parts from their laptops/hardware without permission. Didn't get the password, but the CEO/owner of the company certainly had a surprise. It was a small IT company.Д¬ontacted them on LinkedIn asking for the password and detailing the situation. Returning it seemed like a hassle, I really needed it and this was the only one on sale in Europe.ДЇound the former owner of the laptop where the board came from thanks to the corporate/user name displayed on the password prompt. The seller didn't answer my messages asking for the password, so I assumed he knew there was a password, but didn't know it (and didn't say in the item description). Because it doesn't have to support 1980's Intel architecture they had a lot more freedom in designing security from the start, something Intel can't do unless they can break with backwards compatibility.ДЇunny story, I bought a system board on eBay that had a BIOS password on it. The T2 is a complete SoC running an OS and has a secure enclave. Apple's solution was to get rid of that completely and just emulate that SPI Flash from the T2 chip.

On the other hand, if it is configured that way but a bit flip happens you can't boot anymore and can repair either.

Problem is that you still read SPI Flash which can be modified out of band, so after the CPU ROM reads the ACB it continues reading code which can be altered and if the UEFI firmware is set to 'verify but don't stop running' mode, you can modify all you want and it will work. It starts out with the CPU reading an authenticated code block which contains further code to verify other blocks. Use hardware to Reset an IBM ThinkPad Power On Password If you cannot boot the ThinkPad and only the power-on password is set, do the following: Power off the computer Remove the DIMM cover on the bottom side of the computer. The CPU has a BOOTROM which can cryptographically verify code blocks, the PCH has a CPU that can do the same, and the firmware has signed code blocks. Boot the IBM ThinkPad, and KeyMaker will recover the BIOS password. Normally the CPU talks to the PCH and the PCH via SPI to a Flash ROM. There is no actual BIOS Flash chip, only T2 Flash. Yes, because the CPU boots after the T2, and the T2 emulates the SPI ROM to the PCH.
