SATA Port1 - Port4 [IDE]
Allows you to set the SATA conguration.
[IDE] Set to [IDE] when you want to use the Serial ATA hard disk drives as
Parallel ATA physical storage devices.
[RAID] Set to [RAID] when you want to create a RAID conguration from the
SATA hard disk drives.
[AHCI] Set to [AHCI] when you want the SATA hard disk drives to use the AHCI
(Advanced Host Controller Interface). The AHCI allows the onboard
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
SATA connectors 1–6 in AHCI mode under the OS environment.
SATA Port5 - Port6 [IDE]
Setting this item to [IDE] instead of [RAID] or [AHCI] allows the system to recognize the
optical dirves connected to the SATA connectors 5 or 6 when installing OS.
If you use a SATA optical drive to run the OS installation disk, we strongly recommend that
you install the optical dirve to the SATA connectors 5/6 and set them to [IDE] mode.
The following two items only appear when you set OnChip SATA Channel to [Enabled].
