You are correct, it is the W25Q128FV on the 1796 pro, I cannot get a read from a chip clip type reader using my programmer I believe I am making good contact, Some chips won’t read when installed or maybe my chip went bad. I cannot seem to lift the chip using my hot air station, it looks glued down. I may try again later by shaping a soldering iron tip to only fit 4 pins and lift one side at a time, nothing to lose since the board will not enter bios (only flashes windows logo and shuts off) and I suspect a bad firmware bios update sent by MS. I also may try to carefully grind it off and replace with a standard package SG chip if I can find the bios. Board is otherwise dead anyway. Likely a waste of time
