Hello, good afternoon, I wanted to inquire about something with you, the board that has the SMOOTH l7251 2.2 AAAA chip (up to that point I can see why the rest is not visible because of how burned it is) I have obtained a donor board but its chip is SMOOTH L7251 2.2 991XD V1, Does it make any difference if I change it for something else, even SMOOTH 3.1, and the BIOS is the one I changed and the disk does not start even though the logic board is the same 2060-701590-001 REV A Could you really help me, I don't know what to do, I would be very grateful.
