Hi Matias,

The netX Eth driver is an NDIS miniport driver and does not know anything about upper layer protocols. It just send/receives raw ethernet frames.
The IP Address is part of the TCP/IP Stack configuration which is part of Windows CE itself.

The addresses are entered as additional parameters assigned to the netXeth driver, so that the TCP Stack knows which configuration to use for a specific physical interface.

Take a look at [HKEY_LOCAL_MACHINE\Comm\NETXETH0\Parms\TcpIp]. This is the place where the Windows CE TCP Stack searches for the IPAddress used for physical interface NETXETH0. The ethernet driver should NOT access these keys.

If you need it the way you describe you can either try one of the following (I don't know which of these do work. They are meant as proposals for trying):

• Changes in NetXEthRegisterAdapter to write a new TCP configuration on NIC startup[/*:m]
• Remove the NETXETH0 from registry and try to add this device manually after modifying the TCP settings in registry. (Maybe the sample in "PUBLIC\COMMON\OAK\DRIVERS\NETSAMP\NDISCONFIG\" will help you here)[/*:m]
• Reconfigure the IP address with an application using IPHelper functions[/*:m]
