Spi programmer ami bios10/10/2023 The password checking was easy to find because AMI BIOS sources are available on GitHub. The checking part was in the same module as BIOS flasher (IIRC). Luckly for me, HP didn't used the BIOS Guard/Boot Guard technology and did the checking on the PEI stage with their own module. However, my laptop will reset the BIOS if it fails the signature checking. My HP got a password after a faulty BIOS update (it just hanged up for 30 minutes on one block and I pulled the battery, never do this!) I would like to warn you about signature checking.
