Hi everyone,
I have a CF-53 MK2.
I was able to dump and remove the BIOS lock (user and supervisor password) and flashed it back with a programmer and was able to get into the BIOS.
I did a Load Defaults and now it's asking me for a password.
I can flash the unlocked file again, but maybe someone can point me or remove it all from the dump.
Is it possible to get the Panasonic Logo on boot again, because there is a custom one installed.
Attached is the locked bios dump.
Thank you!

I already figured it out myself and deleted the passwords on these versions as well.

You must post the laptop serial numbers.

I'm sorry.
Model CF-532SLZLNM S/N 7HTSA15216

In the second case, there are no stickers with serial numbers. There is only FCCID: ACJ9TGRI12A

Good afternoon. Help me remove BIOS passwords from two CF-53s. I have 6 of these laptops. Of 4, I was able to remove passwords myself
by changing the block at address AB0C7A - AEFFEF. But in 2 laptops this does not work. in the first case, BIOS number ACJ9TGRI12A
It just asks for a password again. In the second case, BIOS CF-532SLZLNM shows a black screen.
2 original dumps with corresponding names in the archive.

It doesn't have to be exact Winbond, it could be Macronix or some other brand as I mentioned. Inspect the motherboard more carefully.

Good day! Finally i can find BIOS chip and dump it. Can u check this BIOS and repair if its broken ?

Re: Panasonic touchbook cf-53 mk2/mk4

There is no other chip on this board labeled Winbound. Or I can't find that chip. Motherboard in front of me. This chip was next to the RAM.

Re: Panasonic touchbook cf-53 mk2/mk4

You dumped the wrong chip. W25X40CL is not the right one. Bios chip must be 16Mb, for example MX25L128 or W25Q128 and so on.
