    Patent number: 5898845
    Abstract: A computer card mounted in a computer, which has at least one other card having a similar functionality to the card, with the cards being connected to a common bus. Both cards also have overlapping memory, I/O, and interrupt selections assigned by a plug-and-play device. The card comprises a unique handle that is latched to the card by the plug-and-play device. If a card comparator detects a match between the unique handle and the selection data, a selector enables the card.
