This is for the QBlissA9 board.
In hardware our Ethernet port is only 100Mb/s and the default setting is AutoDetect which causes problems with certain Gig hardware (HP switch, other network hardware). Problem is that the port goes in DISCONNECTED state and or doesn't get dhcp IP address. Seems the auto negotiation doesn't work well.
So I'd like to switch it off and fix the port on 100Mb/s full duplex.
I tried with SpeedDuplex setting in HKEY_LOCAL_MACHINE\Comm\ETHNETA1\Parms but doesn't seem to work. Under this reg key there is already a DuplexMode dword.
Can you shed some light on this, how to get this to work? I think your carier board would also have the same problem of not auto negotiating properly.
