You did not take the backup correctly... Kindly use the correct tools to read the BIOS well. Nothing there on this zip file... If you cannot do, just provide Serial # & the EMC # on the back of the cover. Will do it for you

Problem somewhere else, check all power rails in sequence... You are surely missing one rail or a Liquid spill/corrosion on a component. I have a similar problem like this & there was a corrosion on one of the resistence near the SMC.. Check carefully under the MS.

Thank you, the problem has been solved. I found a capacitor exposed to moisture NEAR the SMC THANK YOU

Re: EFIBIN File MacBook Air A1466 (EMC 2632) 820-3437-B

Good afternoon.
I really need help. The problem is as follows:
I bought a laptop, it was on a password (not EFI) and on icloud, the SSD worked, everything was fine, but on a password (. A friend said that the BIOS firmware would solve the problem. I downloaded it somewhere, flashed it and the laptop didn't turn on. The old BIOS firmware was considered incomplete and became non-working. I found firmware 118.0.0.0.0 in this branch (and tried 117.0.0.0.0) (a1466+9.5.3.1526+outimage.rar ), changed the serial number according to the instructions. Flashed, there are no passwords, but does not see the SSD. The disk is working. I put another working disk - also does not see (. What could be the problem? Maybe the firmware didn't fit me? The external disk sees via USB, I boot up, the internal disk does not see in the Disk utility (. mac OS put Maverik, BigSur on the external disk, it did not help ( SMC and PRAM have already been reset 50-60 times (. Nothing helps (. HELP, PLEASE. What did I do wrong?
so, I have a MacBook Air 6.2 13 2014, 820-3437-B EMC 2632, MD760RU

What disk do you not see, though all this is scripted in Russian, I see all your drives, What do you want to do next??? I see you SSD/HDD & media drive, all seems to be ok. Just inform us what you want to do next... This is not a BIOS error, BIOS is ok.

the laptop is loaded from an external ssd, the internal drive is not visible. Power is supplied to the internal disk, the internal disk is original, working (I checked Air on another and formatted it into the GUID Partition Scheme). In the photo you and I see only an EXTERNAL disk

I checked the photo very carefully & I see both disk, DISK 1 & DISK 2.... I think show it to a professial who know the Apple OS he will fix for you, your BIOS is working 100% perfectly, Just some software problem which I cannot figure out. Just show it to a person who know Apple OS & he will resolve your problem hereaffter.

I have an external SSD, it is divided into several disks, they have Maverick, High Sierra, Catalina, Big Sur OS installed on them. I understand how macOS works and unfortunately the internal disk is not visible. In the photo you see only the Kingston external drive and the OS loader
