Allows you to set the SATA configuration. This item appears only when you set the OnChip
SATA Channel item to [Enabled].
[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.
