My mind is not stable these days.

Sorry for the late reply but I ended up replacing the NVRAM region of my BIOS dump from a fresh BIOS, re-flashed it and it worked. Thank you everyone, a special thanks to hoaca388.

How can I reset the setting that I made in the BIOS in this dump, I think I need to clear the NVRAM but I don't know how to. Can someone guide me on how to clear the NVRAM in a Lenovo BIOS?

hoaca, please upload the correct file.

Comparison attached in my next post (#14).

[AHmad_Salal]

I tried comparing the both files and found out that some entries in Intel Image-->ME region-->MDES have changed (images attached). Is this normal?

P.S. MDES is ME debug event service.

bios changes each time you reboot or change settings. do not use the clip is the best solution

[AHmad_Salal]

I tried reading the bios chip again today (file attached) and guess what? The MD5 sums of this file doesn't match with the previous dump that I created yesterday and it is quite confusing for me. Am I not installing the adapter clip correctly or have the contents of chip changed overnight?

P.S. CR2032 coin cell battery is not installed in the motherboard.

I think it's some kind of script, I opened it with notepad and it looks like a script to me

Can't interpret what you are trying to say and what to do with this file (I am newbie in the bios field)?

[hoaca388]

Is there a way to reset/change the bios settings to default in the bios dump file and re-flash the dump with changed settings? Will it work?

Dumps attached (could not upload .bin so uploaded .zip containing two dumps).

Backup bios file ?

I don't have the backup bios file but I tried reading the bios chip using CH431 mini programmer, not sure if was a good read or not so I did it twice. Dumps attached (could not upload .bin so uploaded .zip containing two dumps).

P. S. Suspected bios chip located (please confirm by looking into the dump contents), It's a MX25L12873F
