Network based examples and Redboot on 1c12

Hello.

I would like to know if I can run the Network based Examples (eCos 2.0 for Nios II Tutorial), and use the Redboot in a Nios II Cyclone 1c12 Evaluation board.

I am using the Standard and the Full Featured designs, but it seems that the lan91c111 isn't included at the Nios design.

If that's the problem, does anyone knows if I can find a design that includes this feature?

Thanks.
