Hello, Can you please try the attached patch? Please do a `flashrom -V' after and see if the chip is detected, and reply with that log. If you want to try a write, make sure you have a backup ready and time to spend fixing it in case it doesn't work (another patch may be needed to enable writing). Thanks, Josh
