Dell Latitude 5520 - get to know password from bios chip dump?
#1
Hello,

I am not experienced in electronics, but I really want to check if my idea is possible. 

I have motherboard replaced from Dell Latitude 5520 (11th gen on i5 CPU). 
BIOS/UEFI on that PC is blocked by password which I want to get it  know - even if I need some bruteforcing or stupid manual activities.
There was no computrace activated.

I was happy when I saw many posts about removing BIOS password based on .bin file dummps. I wanted to go little further - get to know the password from the dump.



1. I do not know how thebios chip is identified and  I would ask you if my assumption is good or wrong:

U2502 on PCB >> 8-pin winbond chip 25r256jven 2105 6103 moo14 marked on photos.

I have created some photos , please find it attached.
[Image: fetch?id=3252587&d=1713089251]

[Image: fetch?id=3252588&d=1713089265]
btw I'd tried google and after that I am less sure and aware.
