    Panasonic Lets Note CF-SX4 AMI BIOS Password Needed

    Hello, I have a Japanese exclusive CF-SX4 with intel i5 that has bios password.
    I have tried removing cmos but BIOS password is stored in flash chip. I did see someone has posted a BIOS for it but they have a 16mb chip. Mine came with a 8mb chip. The chip is 25q64FV and have dumped and verified it. None of the backdoor master codes work for it.

    Please have a look, and if you do manage to recover or clean the password, I will be very grateful, I also would like to learn how you did clean/recover it.

    I have tried blanking out the bytes after AMITSESETUP or trying to XOR decrypt it but none have given me a result.

        [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
        by zenius
        Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

        Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

        Help needed in unlocking BIOS Supervisor password - Lenovo X1 Yoga 5th Gen
        by baaligoga
        Good day, everyone!

        I'm encountering an issue with my Lenovo X1 Yoga 5th Gen laptop related to the BIOS supervisor password. I'm seeking assistance and guidance from the knowledgeable members of this community in resolving this problem.

        I am no expert and cannot perform soldering or unsoldering of the chip from the board. Therefore, I attempted to use an EZP 2023 programmer with a clip to extract the BIOS bin file without removing the BIOS chip from the motherboard. The BIOS chip has the following letters imprinted on it: "Winbond 25Q80DVNIG 2026". I used the...
