BIOS settings.  But it's not exactly easy to learn the wake-up code from 
outside a NATted connection.  You've got to know the MAC address of the 
system, IIRC.

Yep, according to http://en.wikipedia.org/wiki/Wake-on-LAN the magic 
packet is set over a connectionless protocol (UDP, IPX) with "FF FF FF FF 
FF FF FF" (in hex, hopefully obviously) plus 16 repetitions of the target 
machine's MAC address, plus a 4-6 byte password.

So I don't think you have to worry about me turning your machine on from 
half a world away.
