Yep i read the manual. info on installing the Sata Driver, overclocking, etc. On boot up there is a message about entering the raid congfiguration menu. I did that, options were "set up raid, delete raid". Not much else on the menu. No info on how to use it to set boot device in the manual. At presernt the machine is working . When I have more time I'll dig into the possibilites available with tis mobo.
