[RAID] Set to [RAID] when you want to create a RAID conguration from the SATA
hard disk drives.
[AHCI] Set to [AHCI] when you want the SATA hard disk drives to use the AHCI

storage driver to enable advanced Serial ATA features that increases
storage performance on random workloads by allowing the drive to
internally optimize the order of commands.
• When this item is set to [AHCI], the information of the SATA connectors 1–6 can be seen
only under the OS environment or during POST.
• For Windows
®
XP OS, you have to install the AHCI driver, so that you could use the
