Hello, I was reading this thread and I have a doubt, the only way to get the bios file is by accessing the bios chip, soldering or is there any other way?
I have an 8fc8 with a locked bios that I cant even access the OS that I installed.
Thanks in advance.

Just trying to understand - what's the process for patching this BIOS? Do you just need to remove the ME section or is it more involved?

Trying to build a quick bash script to automate patching for both Dell & Lenovo - a multitool if you will

Read carefully the message on the screen when you get the message
**** MANUFACTURING MODE ACTIVE ****

The solution is on screen.

Hello!
@Karol, I see you're helping some of the people here who has the 8FC8 prefix.

Would you mind giving me a hand with this?
My BIOS has currently set up an unknown administrator password.

Here's my BIOS dump.
