Then unfortunately I think I was wrong from the start. I thought that the chip that I unsoldered was bios, but from what I am understanding it is not so. Could you tell me somehow, what is the exact chip? Thanks for understanding

I can't find what the bios chip is. I tried to do an internet search but still couldn't find it. Evidently the backup I sent is of another component that I have always unsoldered from that motherboard
