Hi
Yes, a SPI-programmer - converter 1.8v - SOIC8 clip is needed

Hi, please, the Intel BE200 fits in my laptop and work? Only is necessary the modding of BIOS UEFI?
In the 5/8 photo you can see the compatible connectors of motherboard for BE200 001 version.(Key E: Yes),(Key A, Key M, and Mini PCIe, No)":

This is for AX210 006 version, in the photo 6/8 you can see the compatible connectors."(Key A, Key E, Yes) and (Key M, Mini PCIe, No)":

Fits and work, the two cards in my laptop Lenovo Z50-75 purchased in 2017? Is W10 and perhaps W11, not tested yet.I interested only in BE200.

This is a SPI-programmer - converter 1.8v and SOIC8 clip, sure?, I write this page of eBay in my last post before, If not is that, put a url for buy:

All the steps are here:

And repeat that I said before:
What exact chip of the board I need to read with the clip tweezers?

Laptop Model: Lenovo Z50-75 (80EC)
Bios Revision: A4CN43WW (v.2.12)
Using UEFITool 0.21.5/0.28.0 (the same result) HookBeforeBoot and UsbLockDxe modules have been removed from extracted image. Nothing else has changed.
Edited image have flashed back.

I'm using AX210 and no issue is found.

Hello.
This helped me a lot, thank you!
Bought a clip, wired it to a RaspberryPi, used flashrom and it worked out nicely.
