I was told to come here to see if I can modify a Lenovo BIOS on a M75q Tiny where both CPU models from the same AMD family are offered. However my current 2400GE model is the “top” CPU supported and it does not qualify for Win11. Yes I could force it, but since I already bought the 3400GE I would rather have that installed (it powers but it does not post).
Any help or suggestion is highly appreciated.

It does not take that, tried a couple times and it just keep the T55A version. Going to try the USB version/method. Otherwise was looking for a forceful method.

This is BIOS for other revision of the motherboard.
You need to use a hardware programmer to flash it.

A cheap hardware programmer is CH341A. Find it on ebay or aliexpress.
