Re: Panasonic CF-54 Bios Password

Hello
I need help with password reset on panasonic cf-54C. I tried to remove the password myself. But I couldn't do it (I can go into the BIOS and change the settings there, but after rebooting the laptop asks for the old password again). I've attached the bios dumps in the archive.
Please help me what am I doing wrong?

MODEL: CF-54CU005H2
SERIAL: 7CTCA22737

Go to settings and set your password.

Re: Panasonic CF-54 Bios Password

Thank you for your reply
I tried to set my password. But when I do "Factory Default", the password I set doesn't work anymore. It seems that the laptop somehow remembers the old password and sets it again.
I also tried changing different security settings, but nothing helped.

Re: Panasonic CF-54 Bios Password

Thank you very much. It works. If it's not a secret, how did you do it? Did you use a dump from another laptop as a basis?

Re: Panasonic CF-54 Bios Password

Hello, I have a Panasonic CF-54J with a password. Deleting the code (in a hex editor) after the line "AMITSESetup" did not help. Can anyone help me?

Re: Panasonic CF-54 Bios Password

I managed to make a bios dump without a password. I used the dumps from this thread and cleared the ME region. All that remains is to transfer the DMI information. If I understand correctly, it starts at address 0x00800000.

Re: Panasonic CF-54 Bios Password

I am very grateful for help. But have one more small problem. How can I transfer the mac address from an old bios dump? Transferring the mac address (from 0x00001000) in the hex editor didn't help.

Tìm HxD editor. Copy and Paste ( Ctrl + B )

Re: Panasonic CF-54 Bios Password

I got it. Looking through other bios dumps in this thread, I saw that the mac address is often found here 0x1000 and here 0x2000.
I copied these lines of code from the backup bios and it didn't change anything. Then I realized that the problem was probably with the Windows system. It had somehow memorized the Mac's address and didn't change it. After reinstalling Windows, the problem was solved, and the Mac address changed to the one in the original bios.
