Most of that does indeed make sense. When you did your testing, did you use a HPNA card that had a lead connecting it to the motherboard? I am in no way a PC expert, but struggle to see how a HPNA card can receive power through the PCI bus, but an ethernet card requires a lead to plug into the motherboard to receive power. As mentioned, the HPNA cards I hav come accross do not have any such connections on them.

I appreciate the help.
