You probably have no problem, except that the BIOS' displays are a bit confusing. Since you have a SATA drive connected to a SATA port, I guarantee the mobo is using it as a SATA drive, despite what it says. Your manual says the mobo has two original SATA ports, and one newer SATA II port. On the two originals, the only SATA Operation Mode choices are either RAID on non-RAID. On the other (SATA II) port the choices are IDE or SATA. In the latter case, all those mean is that you can have the mobo treat the drive as a native SATA unit, which may have required that your OS (Windows) have appropriate drivers installed, OR it can make that drive emulate an older IDE drive that Windows understands completely with its own built-in drivers. But what it labels those drives is not clear form the manual. In any case, I'm betting that on this early-SATA board, the words the BIOS screens display mean something more like: is this an IDE drive? or, a RAID drive? or, something else we'll lump together under the old handy label, SCSI?
