ABSTRACT:
In a server having several network-interface cards each under control of a corresponding device driver, a method for controlling persistency of a device driver in memory includes determining whether an intermediate driver present in memory. If so then the device driver is set to be persistent in memory. This preserves the integrity of the interface between the intermediate driver and the device driver during replacement of a failed network-interface card.
