No, I meant "slots" in the abstract sense as in device IDs on a PCI
bus segment.  The card I have used has four AMD PCNet chips connected
to a PCI-PCI bridge chip, and has four network connectors on the end.
There are no physical PCI slot connectors on the board.

Sounds like the same thing.  The point is that even though it is a
single card, it looks like a PCI-PCI bridge with four devices behind
it, each using a different PCI device ID.
