[REQUEST] Lenovo Yoga 520-14IKB BIOS Unlock

[McAllidus]

Hi I need some help to dump bios from a Lenovo YOGA 520-14IKB 81EK

No matter how many times I enter the Lenovo BIOS hidden key combination, I cannot access the advanced menu. Entering a hidden key combination only adds a debugging menu. Can I unlock the advanced menu of this bios?

Hi! I'm looking for help with unlocking advanced setup options in InsydeH20 BIOS.

My laptop exact model: Lenovo Yoga 520-14IKB (Type 80X8)
https://pcsupport.lenovo.com/us/en/produ...7A93E0428C

There is no many important settings (some boot opt./pci/sata/etc) and “Advanced” formset is hidden =(
I was looking to apply the “suppress-if patch” method, but this problem seems to require changing asm opcodes in some modules.

BIOS Versions:
V1.06 - factory version
V2.12 - last updated version
It would be great if it is possible to modify last version.

About included in .zip images/binaries:
4qcn36ww.exe - V1.06 official Lenovo exe package
4qcn51ww.exe - V2.12 official Lenovo exe package
CIUSA106.ROM.FD - V1.06 extracted from .exe FD image
CIUSA215.ROM.FD - V2.12 extracted from .exe FD image

Any help would be appreciated. Thanks in advance.
