The ICU includes a locking mechanism that enables you to allocate the system
resources for all or for some functions of Plug and Play and PCI expansion cards.
These expansion cards are
dynamic, which means that they are allocated resources at
system start-up. Device drivers that do not support this dynamic card configuration
are referred to as
static device drivers.
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.
