Zero channel RAID cards are designed to work with the on-board hard drive controller built into the server board you are using. The zero channel RAID card must be inserted into a RAIDIOSenabled slot that is usually on the same bus as the on-board hard drive controller. Ensure that you have inserted the zero channel RAID card into the RAIDIOS enabled slot. Refer to your server board documentation to determine which slot is RAIDIOS enabled. This slot is sometimes labeled “Zero Channel“, “RAIDIOS“, or “MROMB“.
