ASUS M4A87TD EVO

SATA Port1–Port4 [IDE]

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 [IDE]
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 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.

If you use a SATA optical drive to run the OS installation disk, we strongly recommend that

you install the optical drive to the SATA connectors 5/6 and set them to [IDE] mode.
