Install ASRock B450M BIOS on your B450 ATX motherboard.
I purchased the B450 Steel Legend ASRock Board locally without any guarantees, and when I began my test configuration I noticed it displays "B450M Steel Legend Px.x" under UEFI Version. I attempted to update to the standard B450 SL BIOS but it rejected the change. I flashed the B450M BIOS as far back as possible and tried again without success. I searched extensively for solutions but found very little information. How can I resolve this issue, or is this just a poorly made product?
