That Alpha does contain Intel RAID Rom 11.6.0.1702 so there is nothing else I can do.
Have you tried removing that Add-in PCI RAID Card and just using the Built in SATA2 Slots for RAID ?
The whole point of Updating the Intel RAID rom in the BIOS is to allow the use of the On-board SATA Slots with those 3TB Drives.
If you can't figure it out then AsRock will need to work out any issues you have with that BIOS.
