To determine whether your expansion card has static device drivers, check the docu- mentation that came with the drivers. If you are using a static device driver, you need to permanently associate resources with a Plug and Play expansion card, instead of relying on the default Plug and Play behavior. Otherwise, the device driver might not be able to find the card the next time the system boots. This procedure is referred to as locking a card.
NOTE: The locking feature of the ICU is valid only for Plug and Play and PCI expansion cards.
