Can't find boot device after motherboard replacement

[coolnodje]

My boot device isn't recognized after a motherboard replacement.
The new MB is a Supermicro one, I can correclty identify the SSD device in the BIOS menu.

I have changed the SATA port and cables, each time correctly identified by the BIOS, but never recognized as bootable so far.

Is there anything I can do or test except plain reinstallation?

When it is nvme try the compatible mode

Thanks for your answer.
It's an SSD.

I just reinstalled TrueAS.
For what it's worth, I had to do a "format" reinstall, as opposed to just "add a system" (can't remember the terminology used by the installer from the top of my head). System config was kept so minor hassle only.

Well I know a feature in the bios of my Supermicro board to activate a compatibility mode for nvme. I can't help any further, sorry.
