Options for SATA Configuration.
OnChip SATA Channel [Enabled]
[Enabled] Enables the onboard channel SATA port.
[Disabled] Disables the onboard channel SATA port.
The following items appear only when you set the OnChip SATA Channel item to
[Enabled].
SATA Port1–Port4 [AHCI]
Allows you to set the SATA configuration.
[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 configuration 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.
SATA Port5–Port6 [AHCI]
Setting this item to [IDE] instead of [RAID] or [AHCI] allows the system to recognize the
optical drives connected to the SATA connectors 5 or 6 when installing Windows OS.
• When the SATA Port1–Port 4 and the SATA Port5–Port 6 items are 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.
