I have a B450M Steel Legend motherboard and I'm trying to install a Samsung 970 Evo Plus M2 on it, but without success. The SSD doesn't even show up in the BIOS. I disabled CSM, disabled Security Boot, downloaded Samsung Magician, downloaded the latest BIOS version, tried it in the M2_1 and M2_2 slots, and many other things. Still no success.
Anyway, I later tried to install a Gigabyte M2 in the M2_1 slot, and it showed up in the BIOS and Disk Manager on the first try. But there is no comparison between these two M2s and I really want to use this SSD.
Is the Samsung 970 EVO Plus not compatible with this motherboard? What can I do?
