Hm, I was going to measure the real power advantage with a PCI-extender card. But my B44B0 card doesn't seem to work in that extender card. It works perfectly fine sticked directly into the motherboard, though, and other cards like a BCM4318 work in the extender, too. Not sure what this is. The extender has an application note about nonworking cards in the extender and a too big resistor on the board IDSEL pin being the cause of this. Maybe I can try with another machine tomorrow. -- Greetings Michael. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
