A "passive backplane" had slots and a connection for the power supply; the

So far, they have suppored the I/O card and at least one of the VGA
adapters, there is no indication that they 'change' between the CPU card
and the I/O cards.

None, the PCI bus is not controlled by the CPU - it is "passive".
