I have a PCI card that operates independent of the backplane. What I mean by that is that the power is drawn directly from the power supply and the communication takes place via a serial port. This card will literally work without being inserted into a PCI slot. However, I do insert it into the PCI slot because it needs to be physically supported. The "slot section" of the card is electrically isolated from the rest of the card and the slot terminals are also isolated from each other. Here is my dilemma... I can not just take the card out of the slot while the computer is on because it results in a crash. This makes no sense to me. How is the computer even aware that a card is present if no electrical circuits are being closed. To me there is no difference between placing this PCI card or a piece of wood in that slot. Hope I made myself clear. Anyone have any ideas why I can't hot swap?
