 The Ethernet chip does not have WoL capabilities (whereas the old d2 Network does), so we can only simulate it. This is my first attempt to make a software Wake-on-LAN. The Ethernet chip does not have WoL capabilities (whereas the old d2 Network does), so we can only simulate it.

-At an early stage of the boot process we suspend the disk and wait for a Magic Packet before to proceed. So the device is effectively powered and running, just the disk and the LED are turned off. I'm running the program with a Debian Squeeze installation.+At an early stage of the boot process the **''fake-on-lan''** program suspends the USB power, turn off the blue LED and suspend the disk. Then the program waits for a Wake-on-LAN Magic Packet or for a Power Button press/release before to proceed. The device is effectively powered-on and running the Linux kernel, just the USB, the LED and the disk are turned off. I'm running the program with a **Debian Squeeze** installation.

-This is the TODO list:+===== The EEPROM =====
  
-  * Turn off USB power too. +The content of the EEPROM is exposed for read and write via the pseudo file **''/sys/bus/i2c/devices/0-0050/eeprom''**, like with the previous d2 Network model, but the meaning is changed. This is what I know:
-  * Wake on power button keypress too. +
-  * Modify the standard halt sequence so it becomes a reboot followed by fake-on-lan, mybe using the relevant EEPROM bit. +
