Re: Lenovo carbon x1 NM-C881 REV1 Bios dump

Hey, can someone help me with exactly this board? I have already extracted the firmware from the biggest 8-pin chip (MX), but it is only 1 MB in its filesize and I doubt this could be the bios, since I know that it has to be 32 MB. But I don't see any other chip which could be the bios and I have no idea how to extract it with my ch341a. I attached some pictures and I'm gladly asking for help finding the correct chip. Google searches have turned out unsuccesful before....
