Hi!

You need to read another chip (25Q32). Correct dump size for E531 it is 4MB (4 096KB).

Thank you, but I cannot find any 25Q chip on my motherboard.

There are only two chips that should contain bios CFEON EN25QH64, and CFEON EN25QH32.

From which I should read the bios?

Maybe I have bad programmer settings and it didnt read whole bios. Because auto-detect didnt work ,so I have to choose one chip manually, but CFEON not found in menu.

Can you please help me and try to find on internet which chip should I read. And with which programmer settings?

Thank you :)-

Hello, today i finally attach SPI programmer and read content of the bios chip.

Hopefully it is dumped the right way.

But according to this forum it is the right chip - Lenovo Edge E531 boot option vanished in bios - Badcaps Forums

Can you please remove whitelist?
Thank you in advance.

Thank you 
Unfortunately I am a layman who does not know foreign languages I translate everything through Google. I thought it would be easy so I tried following the procedure you wrote to make a backup of the bios with the idea of editing and re-uploading the bios back to my laptop.

hello, I'd like to upgrade my WLAN card and I have the whitelist issue, I need an unlocked BIOS.  Can you please do this with the Lenovo ThinkPad E531 ?

Dobrý den, chtěl bych upgradovat svou WLAN kartu a mám problém s whitelistem, potřebuji odemčený BIOS. Můžete to prosím udělat s Lenovo ThinkPad E531?
