Sorry I mixed up the links, this is what I read talking about a pc,
"In order to enable a radical simplification of the network jungle, the BMW engineers tested the aptitude of the Internet Protocol for applications in engine compartment and dashboard. For their experimental in-car network, they used standard PC and embedded electronic parts and included, among other ECUs, engine control (DME), Dynamic Stability Control (DSC) and dashboard head unit. In addition, a multimedia server and a camera were part of the network; gateways connected conventional non-standard automotive applications."
