Hey,
I want to unlock all hidden options for this laptop, mainly to be able to change the HD520 default DVMT prealloc (can't change it using EFI shell via setup_var)
If it helps, the variable that needs changing is 0x180 to 0x20.
The bios ROM backup can be found here:
https://www.dropbox.com/s/pv6hsjtv7mg6l2...9.rom?dl=0
Please let me know if anything else is needed.
Thank you.

Your bios chip is rewrite protected
Bios mod can be flashed using SPI-programmer+SOIC8 clip only

Hi, I have the same laptop B51-80 and the same request, unlock all menus in this bios. I also have an external SPI programmer used to wipe intel ME. Can you please explain how to do this and what I need? Really thank you.
PS:the BIOS is here: https://download.lenovo.com/consumer/mob...cn35ww.exe

Hi, I need to unlock the bios for my Lenovo B51-80, to enable AHCI for my 850 Evo SSD. The current bios installed is InsydeH20 Rev. 5.0 (D7CN35WW (V3.08)), however there is no access to this setting, and I think it needs to be unlocked. Kind regards.

Hi, thanks for the help
Is there any way I could change the SATA interface to AHCI without doing this?
