Hi all! I am wondering if it's possible to remove the bios whitelist easily. Because of the whitelist, my external gpu setup that I got recently refuses to work. If it helps at all, I know that the wifi card that used to be in the slot was the intel 8265ngw. Here's the bios link if that helps too: laptops and netbooks :: thinkpad x series laptops :: thinkpad x380 yoga :: 20lj :: 20ljs20n00 :: mp1e15eb - Lenovo Support US
Thanks for your help!

We've had a stack of recurring questions from with problems getting a mPCIe eGPU working. This includes GPU-Z not reporting no clock details, error 10/43 or even not being detected at all. Overall it's more troublesome getting mPCIe working than say expresscard or Thunderbolt.
Here's some common problems and some troubleshooting steps to correct them.
Getting a black bootup screen, resolving error 10/43 or ACPI_BIOS_ERROR win bootup messages
Here the BIOS doesn't know what to do when it sees an eGPU. So the solution is to not let the BIOS see it. Do that by setting the delays on the eGPU adapter (CTD/PTD - EXP GDC or CLKRUN/PERST# on PE4L/PE4C). Boot with eGPU adapter in the wifi slot into Setup 1.30 or Windows. Is the eGPU detected?
I'll add that should error 43 continue AND you have a NVidia dGPU as well as NVidia eGPU then it's likely because of having the mobile NVidia and desktop NVidia drivers loaded simultaneously. Proceed to uninstall ALL your NVidia drivers, use "DDU" to clean NVidia registry entries and do a 'clean' install of the latest NVidia desktop driver.
mPCIe port that hosted the wifi card disappears when connecting an eGPU in it's place
Use the Setup1.30 PCIe Ports->enable to enable the missing port.
eGPU does not get detected
Overcome mPCIe whitelisting by booting with the wifi card and then hotswapping in the eGPU. That way the BIOS will enable the mPCIe port to work.
1. Boot with wifi card into Windows, sleep system, swap wifi card for mPCIe eGPU adapter and ensure eGPU is powered on, resume system. Do a device manager scan in Windows. Is the eGPU detected?
2. Boot with wifi card into Setup 1.30 *carefully* hotplug the eGPU adapter in place of wifi card. Hit F5 to rescan the PCIe bus. Is the eGPU detected?
If this enables detection then avoid this tedious hotswapping by seeking a unwhitelisted modified BIOS for your system OR test the Setup 1.30's PCI ports->undo_whitesting feature.
eGPU still not detected - set the PSU to be permanently on
The latest EXP GDC and BPlus eGPU adapters try to manage the PSU to only power on after they detect a signal. This can cause a race condition where the eGPU isn't ready to go when the CLKRUN signal is asserted.
Avoid this by jumpering the PSU so it's permanently on rather than being managed. Depending on the PSU you are using refer to the following doco on how to do that:
eGPU still not detected - a non-standard mPCIe implementation by your vendor?
PERST# mPCIe pin 22 may need to be isolated due to a non-standard implementation by your notebook vendor: http://forum.techinferno.com/enclosures-adapters/10812-pe4x-series-understanding-clkreq-perst-delay.html#post142689
eGPU still not detected - faulty hardware?
If you still don't get detection then test the video card and eGPU adapter in another machine to confirm neither is faulty.
NVidia driver stops responding
EXP GDC, PE4H 2.4 and PE4L 1.5 all use a socketted cable and therefore are not true Gen2 compatible device. This error indicates there was transmissions errors.
The solution is either to get a better Gen2-compliant eGPU adapter such as PE4C V3.0 or PE4L 2.1b (both with soldered cable), or downgrade your link from Gen2 to Gen1 using BIOS options or Setup 1.30

Who can help me with modding and getting my 980M working?
I replaced the M6100 that was originally in the laptop with a 980M but I can't seem to get it to work. I keep getting Code 43
the Hardware ID : PCI\VEN_10DE&DEV_13D7&SUBSYS_15CD1028
I heard i need to modify and INF file but i have no experience with it
The vBIOS is from MSI
If someone wants upgrade Wi-Fi card and remove witelist, or unlock hidden additional menus and settings, or unlocked vbios for overclock NVIDIA card, then you can post your request in this thread.
It's for Lenovo Z710, Z510 only!
I am very aware of the healthy skepticism of most if not all of you. I therefore kindly ask of you not to spew out the fact that its impossible to build a laptop at me but instead attempt to help me to make this somewhat possible for the next person interested in the idea.
I already have:
somewhere to buy a screen: https://www.laptopscreen.com/English/ somewhere to buy a motherboard, CPU, GPU, RAM, storage and other things although I would be very interested should you recommend other places where I can get these
I will build the cooling system myself
somewhere to buy a laptop shell (I am aware of how difficult it is to find one and am therefore very flexible on all other components) somewhere to buy a power supply
Thank you very much for helping me and pushing the possibility of building a custom laptop ever so slightly more realistic
