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

messages during the POST. Configuration options: [Enabled] [Disable link]
