Some of them have chips on them , and some have no chips at all. Some are a solid pcb , some have a ribbon.

In order for this to work on any motherboard , all the boards current pci slots would have to be connected to each other in parallel I imagine.

So I flipped a couple boards over and yeah , for the most part the regular pci slots look like they are all connected parallel with each other. Although according to wikipedia many of the pins are not parallel , so I wonder how this card gets around that. Maybe only the chipped cards can relay the data.

So I'm wondering if these work. How they work. Or , are they supposed to be inserted into proprietary slots that happen to use a pci connector.

You probably cannot use cards that need bus mastering (at least not two of them), but other than that it should work.

Signals that are not shared across PCI slots are configuration space, interrupt and bus master related.

Configuration space: This is absolutely important, thus some logic must exist to turn the two slots into a multifunction PCI device (from the mainboard side of view).

Interrupt: A PCI slot typically gets 4 interrupt lines, and sharing is also possible. They can be distributed between the two cards.

Bus mastering: A mechanism is described to have bus mastering on multifunction devices: https://books.google.de/books?id=tbIvDKSZbR0C … unction&f=false
It probably needs some additional logic too.

So with adapters without any chips I would be sceptical.
