My issue isn't massive, but I'd like to get this solved since I'm trying to fix a friend's laptop.
A botched BIOS update by Lenovo bricked this laptop, so I used my BIOS programmer to reflash the BIOS on it and saved it from an early demise. All is good now, but the BIOS reports the S/N, MTM and UUID... -
I had a desktop form factor mini-server die on me a few weeks ago. Through my initial diagnostics, I was convinced it was the motherboard because when I shorted the Green wire on the ATX connecter, the multimeter gave me all the correct voltages on the various pins of the ATX connector and 5VSTB was also correct.

I received a 2013 Macbook Air A1466 A1466 820-3437-B motherboard WITHOUT a bios chip. I got a new bios chip and reprogrammed it. Macbook now powers on but doesn't boot the SSD.

Could someone help me?
I have a Macbook Air A1466 EMC 3178 - 2017, board 820-00165 and sometimes the boot interrupts with an image of a folder and a question mark.
Could it be the BIOS?
