ga-x79-ud5 boot drive order

[adamsoundSTL]

got this board up and running with an i7 3930k and GT520 graphics.

however when i go to the BIOS to set the boot drive for my SSD connected via SATA, all I see is that drive (and my other SATA drive) via UEFI: not via SATA. somewhere I read that you can find it as P0: or something but don't see it that way.

I DO see the drive as SATA under the legacy boot options, but selecting it there doesn't seem to help - though I select it the BIOS still doesn't display it as the setting, as if it's not enabled. Tried disabling all three priority boots above but still no love on the SATA drive.

Any help appreciated!

few things to add:

the SSD drive via SATA shows up first in the list when I hit F12, and boots fine.

realized that my USB stick drive is still on the computer when I booted just now - any reason having that inserted should cause a problem?

thanks!
