Actually the guy who hosts my servers at m5hosting.com was showing and telling be about some BIOS-over-lan or something like that. I can't remember exactly what the feature was, but certain motherboards (some Supermicro models in particular) let you access "something" over LAN. Maybe that something was BIOS or serial console, or video console, I can't remember. IIRC when you access that stuff over lan it is like a mini HTTP server and sends you some Java applet or something. Pretty neat.
