I managed to solve it.
The MX77L12850F chip can be replaced with Winbond 25Q128FV, and the content can be found in the attached file.
I update the description data and attach the working file. It is 100% tested.

You are right. Closer to PCH was this chip as seen in photo1, but I found another flash chip, MX77L12850F close to the second M.2 connector, photo2
I didn't find this face in the list from the TL866C programmer, but I'm documenting myself and coming back.

Asus FX506HC-HN053 bios password unlock
Hi!
It's an Asus FX506HC-HN053 laptop.
After trying to remove the bios administrator password, it asks for the password, but no longer accepts the known password.
I'm asking for help.

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,... -
Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder... -

Hello,
Could someone help me out either decrypting the administrator password, or removing entirely? Password was forgotten by user.
Asus S533F serial L6N0CV190141266
Current BIOS firmware version is X521FA-305
Thank you!... -
Hello,
I have spent the last hour on this and I guess this is just over my head, so here I am.
I have an ASUS TUF GAMING Z790-PLUS WIFI motherboard here that needs to have the BIOS updated in order to accept the latest CPUs.
The BIOS chips seem to come as a set of two: GD25B64ESIG and GD25B128ESIG. My guess is one of them is a fail-safe for the main BIOS? I really don't know. Or one of them is ME and other is BIOS? I don't know.
Anyway, I took dumps of both chips and then downloaded the latest update for this motherboard from ASUS's website...
