Hi!

I recently got a Western Digital SN850X 1tb but I can’t get it to detect in BIOS.
Motherboard http://www.asrock.com/mb/AMD/AB350 Pro4/#BIOS. I have tried booting
with all other sata drives disconnected. I've have tried to reseating it in m.2_1 multiple times.



BIOS version 7.40 Latest
What could be a problem ?
