post the original contents of the bios chip..

The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

I have a strange behavior with unlocked 8440p.
Admin password removed succesfully, i can enter bios with F10 BUT i can't change any setting, whatever i do when i save, exit and enter again BIOS it's not stored, like it's locked on specific settings.
I tried factory defaults, secutiry reset, bios update through Windows but no success.
Seems like the admin password really gone but the permission to make changes in BIOS remained.
Attached is the unlocked file that i flashed.
What do i miss?
