Lenovo Yoga 11e BIOS chip swap for wifi card compatibility

[Guaculo]

Hi, i got a Lenovo Yoga 11e that had a bad motherboard. I purchased a replacement motherboard but its a model variation from the original.

Now the new motherboard wont boot with the OEM wifi card. On the lenovo page it says the new motherboard needs a N-7260 wifi card, and the one i have its a AC-7260.

I swapped the 2 bios chip from the old mobo (U40 and U38) to the new one in hopes i could get the wifi card to run, but it wont work, even the serial number stays the same as the new motherboard (the laptop runs fine only this 2 issues).

Is this information stored somewhere else?
