@CursedSilicon Mmyup! IIRC even the official Intel article about CNVi has a disclamer at the bottom about only working with specifically designed boards which support CNVi. I assume it's half a cent cheaper to throw a few more transistors into the PCH and add a couple of extra PCB traces or whatever the actual hardware change may be combined with a very stripped down wireless card that's basically just some RF magic than to use a full PCIe and USB WiFi/Bluetooth module
