Are you sure you've got that the right way round? I though 5V PCI cards have a second slot in the connector, 3.3V's do not. So you can't put a 3.3V card in a 5V slot, but can put a 5V card in a 3.3V slot. 3.3V cards that can handle 5V are the exception, and to add more confusion, there are probably boards with 3.3V style connectors, than can supply 5V if required too. Fun, eh? I can't get my hands on a PCI-X equipped board the moment to verify. Do PCI-X slots have both 3.3 and 5V versions? -- Mike Williams
