Hi,
I have a Thinkpad T440p and it has severe connectivity issues. So to install a different wifi card i wanted to remove the whitelist and got me a programmer with bios clip.
This is what i did so far:
- Laptop was working
- bios chip is winbond W25Q32FV, 32Mb, was detected correctly by programmer
- Dump bios file 2 times, comparing and checking for FF FF, this worked well, all dumps are the same (attached)
- following this:

- modified the dump, signed it
- flashed back...
