Anyone heard of this problem? I just finished setting up RAID1 and then I discovered that anything that was plugged into the SATA2 header would not show up in BIOS. My HP multi dvd would not show up. If I plugged it into the GSATA2 header it would show up? I pulled the board and sent it back for a replacement. I could not find anything in bios that would allow you to turn off or on the SATA2 header. Anyone have an idea of what may have caused this. Could it just be a bad header?
