Lenovo LA-K321P two "bios" chip

[jasko_jacker]

This motherboard has two chips one is UC4 -> 16MB which contains the main bios without the me inside, in fact if
use ME analyzer to check, it returns (see pics) "file does not contain intel engine/graphics/indipendent firmaware".
The second chip is UC2 -> 8MB, it contains ME data (see pics) and other things like PMC. If there are problems
like power management or ME, the chip to be rebuilt is UC4 and not UC2. Anyone confirm this?
I unzipped the exe file via this guide on the official Lenovo website
https://forums.lenovo.com/t5/Gaming-Laptops/GUIDE-How-to-extract-BIOS-from-Lenovo-BIOS-Update-Package-such-as-ATCN37WW-exe/m-p/5008973
and you get a file that contains data from both chips

Post the laptop serial number and full laptop model please https://www.badcaps.net/forum/troubl...before-posting ,also post both of your bios backups. Both bios dumps need joining together before the ME firmware can be cleaned.Is that what you want the ME firmware cleaning,whats the problem.

the problem is that the power supply that uses a usb c does not receive the signal to convert the 5v into 19v. I was trying to understand where the signal that the TPS65994AD chip should receive comes from. I don't have the boardview but only the pdf which is not complete, another laboratory deleted both chips because they didn't understand how the system works with the two chips (8MB and 16MB) so I extracted the two firmwares from the Lenovo website and asked for a confirmation from someone because now everything works but I wanted details on how to clean me in case I wasn't able to extract the firmware from the site but only had the dumps. For example, I attached the files that I extracted but how do I test them with ME analyzer because if I only test the 8MB one I get the error shown in the photo

If you wanted to clean the ME firmware both files must be joined together before Flash image tool will work, and also the error message with ME Analyzer will not show once joined https://www.badcaps.net/forum/troubl...87#post1457587 .After FIT has built the new image it will split the files back to 8 and 16MB
Some machines can have 2 bios chips when corporate ME firmware is used,and a single bios chip when consumer firmware is used.
