The latest revision of the Ethernet Shield includes a micro-SD card slot. An SD card library is not yet included in the standard Arduino distribution, but the sdfatlib by Bill Greiman works well. See this tutorial from Adafruit Industries for instructions (thanks Limor!).

The latest revision of the Ethernet Shield includes a micro-SD card slot, which can be interfaced with using the SD library.

Changed lines 15-16 from:

The shield must be assigned a MAC address and a fixed IP address using the Ethernet.begin() function. A MAC address is a globally unique identifier for a particular device; inventing a random one should work, but don't use the same one for multiple boards. Valid IP addresses depend on the configuration of your network. (It is possible to use DHCP to dynamically assign an IP to the shield, but this is not yet implemented.) Optionally, you can also specify a network gateway and subnet.

The shield must be assigned a MAC address and a fixed IP address using the Ethernet.begin() function. A MAC address is a globally unique identifier for a particular device. Current Ethernet shields come with a sticker indicating the MAC address you should use with them. For older shields without a dedicated MAC address, inventing a random one should work, but don't use the same one for multiple boards. Valid IP addresses depend on the configuration of your network. (It is possible to use DHCP to dynamically assign an IP to the shield, but this is not yet implemented in the Ethernet library.) Optionally, you can also specify a network gateway and subnet.

Connect the shield to your computer or a network hub or router using a standard ethernet cable (CAT5 or CAT6 with RJ45 connectors). Connecting to a computer may require the use of a cross-over cable (although many computers, include all recent Macs can do the cross-over internally).

Added lines 9-10:

To use the shield, mount it on top of an Arduino board (e.g. the Diecimila). To upload sketches to the board, connect it to your computer with a USB cable as you normally would. Once the sketch has been uploaded, you can disconnect the board from your computer and power it with an external power supply.
