Old Ethernet Shield W5100 compatibility with Arduino DUE

Hi there, I don’t know if this topic is appropriate for this section of the forum, but I need some help in here!

I have the Old Arduino Ethernet Shield W5100 that don’t have the IOREF pin like the new R3 version.
I would like to know if it’s compatible with Arduino DUE sience the operating voltage of the Arduino DUE is 3.3V.

So the IOREF pin (used by shields to know if they should operate as 3.3V or 5V devices).

Follow attached a picture of the Ethernet Shield Shield I have!
Thanks!
