I thought it was not about supplying power, but about the logic voltage, like with the varying voltages of AGP <?>x slots. Isn't a PCI slot, even on a PeeCee, either 5V or 3.3V forever, depending on how it's wired, and never adaptable to the card inserted? and necessarily so, since the logic pins of a PCI slot are shared with other slots and thus other cards on the ``bus'' which, if slots tried to be dual-voltage, could be cards of the wrong voltage? so, only cards can be dual-voltage, not slots? And a slot signifies which kind it is by whether the keying bar is in the back (5V) or near the card edge (3.3V)---many cards have two openings for keying bars, but you'll never see a PCI slot without a keying bar in either one spot or the other. I have been assuming this order of affairs but don't know for sure.
