Disable your RAID, and try to detect it. You can't use both. I know Iwill's with RAID, you can't use a IDE card at all! If disabling the RAID options doesn't work, I think you're out of luck. Why do you need 3 or 4 IDE channels anyways? Put you're HDD's on the RAID channels. You don't have to run them with RAID. Just letting you know if you didn't already know.
