Hello, I had a funny story earlier. My MacPro 4.1> 5.1 is equipped with three SSDs:

1 AHCI SSD on PCIe with 10.14.1 (main volume)
1 SSD sata with 10.12.6
1 SSD sata with Windows 10

I restart the Mac on my SSD sata with 10.12.6, I do what I have to do, but I already realize that the icon of my AHCI disk appears with a generic icon and external disk (while it is custom). I decide to remorttre the custom icon but the Mac does not want to copy it on the generic icon. In short, I do not pay more attention and decided to reboot on my main AHCI 10.14.1 SSD (via System Preferences / Boot Disk, since I have a RX 580 GPU).
The surprise ! the Mac does not see the 10.14.1 volume, it only sees the Windows 10 and 10.12.6 disk. I admit to having a hot shot at the moment lol.
After reflection, I decided to start my external HDD (main clone 10.14.1), it is seen by 10.12.6 which allows me to restart on the external drive.
Once the 10.14.1 (external) turned on, miraculously my main AHCI SSD reappears in "boot disks".

More fear than harm, but would you have any idea of the problem? I have already navigated without problem with AHCI 10.14.0> SSD 10.12.6 and returned to the first snas problem but not since I made the update 10.14.1.

Is the problem coming from the 140.0.0.0.0 firmware? That's all I can see ?

Thanks for your help

You are looking into the wrong thing, your problem is not related with 140.0.0.0.0.

I have all this correctly working into a SSD7101A installed into my 2010:

970Pro 512GB
PM963 128GB
SM951-AHCI 128GB
SM951-AHCI 512GB

With my 2009 with 140.0.0.0.0, I have two SM951-AHCI 256GB into two Angelbirds PX1.
 
may be badly started under 10.12.6, in any case it was strange because the ssd ahci is well wrought on the desktop but impossible to see the system in "boot disks" from Sierra.
