SATA RAID/AHCI Mode
Enables or disables RAID for the SATA controllers or configures the SATA controllers to AHCI mode.
Disabled: Disables RAID for the SATA controllers and configures the SATA controllers to PATA mode. (Default) AHCI: Configures the SATA controllers to AHCI mode. Advanced Host Controller Interface (AHCI) is an interface specification that allows the storage driver to enable advanced Serial ATA features such as Native Command Queuing and hot plug. RAID: Enables RAID for the SATA controllers.
Allows you to decide whether to configure the SA TA controller to AHCI mode.
IDE Configures the SATA controller to PATA mode. (Default) AHCI Configures the SATA controller to AHCI mode.
Edit: Actually, does "Onboard SATA/IDE Ctrl Mode (GIGABYTE SATA2 Chip)" refer to the non-intel chip? The instructions for this specify it as the JMB322 SATA Controller. The instructions for the SATA RAID/AHCI Mode are specific to the ICH10R SATA Controller.
Edit 2: Answered my own question after reading a bit. I'll be enabling the first option, not the Onboard SATA/IDE Ctrl Mode, which controls the non-Intel SATA ports.
