Hi Everyone,
I'm facing a problem with a locked bios with a password and i can't find how to remove it...
The small computer is only booting on a M2 ssd Windows partition and i get a "signed partition error" if i try to boot on the same SSD with another Os (linux for example).
the Computer is a Unowhy small pc
N° UYM6524702229
After failling trying to boot on other "none Windows" partition, i wanted to try to remove the bios password.
My first attempt was to get the bios dump from windows with AFUWinx64. After editing the hex file, i removed the "password" parts of this dump but i got an error when i tried to burn the modified bios (write protection?).
I then tried to do more "hardware"... i found on the motherboard two chips:
-1- Winbond 25Q16JVNJQ
-2- Winbond 25Q80DVNJG
From what i found on internet, the bios chip with the password should be the second one (25Q80).
I desolder this chip, and i did a dump of it with my chip reader.
I opened this last dump, but i can't find the same part where password should be stored....
Can someone help me? is it the good chip?
I attached the dump of the 25Q80, if someone can help me if it's the good one or do i have to check the other 25Q16 chip?
Many thanks
