SPI Chip is probably Winbond W25Q128JV ?

Computrace (DeviceFreeze) prevents booting.
Would try to clean it myself but this is my first time trying this and I have no idea about the DMI address offsets or whatnot on this chip.. 😔

Thank you in advance!

Unlock it yourself. E7A8 codes from biospw.org work OK. If you can find out how to turn off CAPS LOCK you should be able to enter the code as its case sensitive. Use a US QWERTY USB keyboard
