Bare arduino plus ethernet board.

Going to try and experiment to hook a bare arduino to an ethernet board. According to the documentation for the board only six intelligent pins are connected directly. We will see how true that is.

Lines required by the ethernet board. Pins usage on Arduino 

D2 - Connects the INT pin of the W5100
D3 - Contral the reset of the W5100
D10 - Used for SPI Chip Select
D11 - Used for SPI MOSI
D12 - Used for SPI MISO
D13 - Used for SPI SCK

Getting ready to test the unit. Need a 3.3 volt source instead of 6v.
