Assemblies missing in the Panda II firmware?

The code in my program worked great until I added an 'If(!Ethernet.IsCableconnected) statement to the code. After that, I got errors even though the program built ok. Is this a firmware corruption or yet another limitation of the Panda II/Wiznet5100?

Here is my error:


Link failure: some assembly references cannot be resolved!!

Assembly: FEZ Panda II Application ( needs assembly ‘GHIElectronics.NETMF.W5100.Dhcp’ (

Error: a3000000

The program ‘[3] Micro Framework application: Managed’ has exited with code 0 (0x0).
Waiting for debug commands…

Here is the code:

This method doesn’t work on wiznet

For future reference, What resource(s) can I reference so that I know what will work with the PandaII and wiznet hardware? As of now all I have besides this forum is the GHI Docs and micro framework info.

What you have for FEZ Panda is in one assembly and in one namespace, that is w5100.
