[REQUEST] Lenovo Yoga 500-14ISK (D3CNxxWW) BIOS Unlock

[shaq.ir]

Hello guys,

I was wondering, can bios be unlocked to change CL timings or all advanced settings.

Default bios supports CL11 ram, but I want to use CL9 ram. Is it possible ?

Thanks.

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

Oh cmon. I hate these limitations, protections etc.
Anyway, thanks buddy.

Can you unlock advanced menu in my phoenix UEFI BIOS?

Here's link to BIOS:

Otherwise if any could unlock the bios instead of passing me an old bios that probably won't solve the situation?

I am requesting an advanced menu unlock for my Lenovo Yoga 500-14ISK to resolve a persistent graphics routing / resource mapping issue with my discrete GPU. My OS detects the card on the PCIe bus, but it fails to load the driver properly. I need access to the hidden Advanced chipset/PCI configurations to reallocate resources manually.

System Specifications:
Laptop Model: Lenovo Yoga 500-14ISK (Skylake Platform)

Motherboard Platform: LT41_SKL_MB 14292-1

BIOS Vendor: Phoenix SecureCore Technology

Current BIOS Version: D3CN39WW

Processor: Intel Core i5-6200U

Integrated GPU: Intel HD Graphics 520

Discrete GPU: NVIDIA GeForce 920M

Backstory & Hardware Status:
The discrete GPU stopped initializing normally after a multi-boot setup environment (which has since been completely wiped and the EFI partition reformatted).

To verify the hardware isn't dead, I ran a hardware bus scan under Linux (lshw -C display). The system explicitly enumerates both display engines on the bus layout:

VGA compatible controller -> Skylake GT2 [HD Graphics 520] (Bus info: pci@0000:00:02.0)

3D controller -> GK208BM [GeForce 920M] (Bus info: pci@0000:01:00.0)

The physical lanes are working, but the Windows and Linux driver stacks cannot cleanly communicate with the device allocations. I want to unlock the hidden internal layout configuration menus to manually review and toggle settings like PEG Link Control, ASPM, or advanced power states for the discrete chip.



Backup File Link:
I have successfully taken a byte-for-byte platform dump of my active motherboard firmware using the Intel CSME Flash Programming Tool (FPT v11).

Link to my  BIOS dump file: https://drive.google.com/file/d/1Ve-5Dgd...drive_link
Link to my  BIOS install file downloaded from Lenovo:  https://drive.google.com/file/d/1naeXOFh...sp=sharing
or
https://download.lenovo.com/consumer/mob...cn39ww.exe

If any developer or modder can patch this backup file to expose the hidden Advanced and Chipset tabs, I would be incredibly grateful. I have the necessary environment tools to flash the modified image back onto the platform.

Thank you very much for your time and expertise!

Hi
Do you have a SPI-programmer?
