Hello, how can I remove the bios password and the Computrace ?
Can you help me? is there a gide on how to flush the chip?
How these bins are generated? Any tutorial, I guess is on binary leve update somehow based on service tagm right?

[Valentin Florin Benciu]

I need to extract it form teh BIOS chip, right?
Also, can you share with me the exact steps that you took and the tools that you've used to unlock the bios from the bin?

Thank you for your reply.
