Thanks. What do you mean "something to do with the layout of the drives and the fact that there are so many especially "green" versions" . The "layout" I can understand, but what about the "green drives".
Please note that the two Hightpoint Sata cards in the pcie slots have been in the system for over 3 months with no problems.
When I say that the system will not boot into the OS, in this case WHS 2011, I mean it never gets to the words "Loading Operating System". Only when a powered HD is plugged into port 3 does the board fail to get to to the words "Loading Operating System". Does this term, "Loading Operating System", come from the boards Bios or from the OS? I believe from looking at the posts on this site that it comes from the Bios.
Please note also that I can unplug the power from the HD plugged into port 3 and once I get past the"loading operating system" message, I can replug the power to that hard drive the drive will come up in the OS. Kinda clumsy way though to boot a computer.
