So the DSS fully boots but with another system but not the Intel SR2300. If the DSS can be seen in the BIOS then try after POST enter the escape key and select the "Testing mode" function to see if this helps. I will admit this is very strange as the NAS-R3 Enterprise is of the same build as the DSS. There is a newer release of the DSS that I can provide you. Please email me and I will provide you access to this release and it is not beta.
