Switch in BIOS its operation to AHCI, you will see attached drives. Configure these drives as software RAID. As a matter of fact neither of fake RAID cards were ever supported by systems I know of (excluding MS Windows) as RAID cards. That is where jargon “fake RAID” widely used by Linux Folks comes from. System board manufacturers (motherboard is common jargon for system board for over 20 years) share their part in the spreading of fake RAID chips. Fake RAID chip is cheap (pun intended), so adding it to system board does not increase its cost much, but increases it apparent value in eyer of uninformed (I should say ignorant) mass consumer. It is probably time to call garbage (fake RAID) garbage and not expect from it to behave as real RAID (hardware RAID), and definitely not put blame on the system for garbage hardware being garbage hardware. Sorry about long post, I keep being upset by manufacturers who do this.
