ENC28j60 webserver from SD card

I found a code to use the ethershield to run the website stored on the SD card.
It works fine with the original v5 5100 ethershield i have.
Code found at topic: Arduino Forum

When I connect the ENC28j60 and a SD card and the CS pins simulair as the ethershield it doesn't work.
I use the enc library.

The index file is read by the browser then nothing happens.
After a while the browser repports error 404 send from the arduino.

Sketches only using the SD or Ethernet are working fine.

Using software 22. Checked al the setting of the CS ports.
Using arduino mega 1280.
Pin 53 CS ethernet. Pin 10 still setup as output high.
Pin 4 CS SD card

Is it possible to use the Enc ethernet this way?
Has someone a working code?

Many thanks.
