RAID is supported on the Marvell 9128 SATA 6G chipset. In order to access the Marvell RAID configuration utility for SATA6G you must first enter the BIOS and set the SATA 6G option to 'AHCI'. Then you can save and exit the BIOS and during POST upon the reboot process press Ctrl+M to enter the Marvell RAID configuration utility.
