WOL works like this:

- The server software doesn't let the PC go to sleep when there are DARs powered on (ie, the icon is blue). The screen can go off, and the hdd can spin down though.

- When the last DAR is powered off, the pc is allowed to sleep (NOT hibernate).

- When DARs power on, they send 2 flavours of WOL packet, one suitable for PNA cards and a normal ethernet WOL - to the last known mac address of the server. Note that if you hard power down a DAR (ie remove power altogether), it then doesn't know the mac address of the last server and will most likely fail to wake it.

- The WOL packet brings the server out of sleep and it will serve music to the DAR.
