Hi!
I'm using B450M Pro4 Steel Legend on 10.30 BIOS version. My CPU is R7 5700X.
And I tried to put M2 Nvme SSD ADATA LEGEND 800.
1st SSD works fine in ultra m2 slot, but 2nd SSD not working.
Also I have SSD 2.5 SATA and 3.5 HDD.
First time my HHD disappeared when I plugged 2nd nvme, but after I put HHD in different SATA slot and it appears.
What I can do with 2nd m2 slot?

On Page 4 and page 29 of the manual it says:

*M2_2 and SATA3_3 share lanes. If either one of them is in use, the other one will be disabled.

so moving the HHD to a different sata port like sata3_1 , sata3_2 or sata3_4 you can use that M.2 slot

Hope this helps

Already tried. Nothing. Problem that 2m_2 slot accept only SATA3 and my SSD on PCIe inteface so, that the problem. I'm hoping for some new BETA version of BIOS for "Forcing slot to accept PCIe interface", but I don't know is it even possible
