Sorry, I guess I was a little bit vague

My idea was to locate those extra lines required by the adapter board on the link picture, and then attach these directly rather than using second slot PCI adapter.

The question is, are these signals likely to be on the motherboard?
Surely the chipset used iis a standard one, and not hacked to disable the extra PCI slots, they just simply dont wire up the pins on the chip to a PCI socket?
