Is this possible on P320 (non-tiny) #3

I am interested to know if there's a possibility of bifurcation on the Lenovo P320 in a similar way of hardware modification?

How did you discover/trace the resistor locations to modify the CFG? Do these map from socket pins?

You can follow my way to find out the pins and the resistor locations on the similar type.

I ended up using silver paste epoxy directly on the CPU pin pads, it worked :)

Now using a x8x4x4 adapter to get a x8 PCIe card + 2x NVMe M.2 SSDs on a single x16 slot.
