控制硬件驱动程序选择

Controlling hardware driver selection
Abstract:
Technologies are described herein for controlling the selection of drivers in a firmware environment for managing a hardware device based on a user preference. A user preference that specifies one driver being preferred over another driver for the hardware device is received, for example, through a user interface provided by the firmware environment. According to the user preference, a sorted driver pool that contain drivers available for the hardware device is created by listing the preferred driver before the non-preferred driver in the sorted driver pool. A driver stack is then built from the sorted driver pool by examining each driver in the sorted driver pool in the order they are listed in the sorted driver pool. The preferred driver is then put into the driver stack before the non-preferred driver and thus is associated with the hardware device first.
