    • A system and method for initialization of a computer system is described. Faster initialization of a computer system is possible by allowing certain device driver initialization tasks to overlap with other initialization and operating system tasks. option-ROMs resident on hardware device drivers define the initialization tasks to be performed prior to device driver initialization. Initial computer code for booting the computing device, such as a BIOS, is executed. As option-ROMs for hardware devices are scanned and executed, specific device initialization information is accessed from the devices and placed in pre-defined buffer areas. These accesses occur in parallel to other start up tasks. When device drivers are loaded, some of their initialization has already completed, thereby shortening the time necessary to boot the system.
    • 描述了用于计算机系统的初始化的系统和方法。 通过允许某些设备驱动程序初始化任务与其他初始化和操作系统任务重叠,可以更快地初始化计算机系统。 驻留在硬件设备驱动程序上的选件ROM定义在设备驱动程序初始化之前执行的初始化任务。 执行用于引导诸如BIOS的计算设备的初始计算机代码。 随着硬件设备的ROM-ROM的扫描和执行,从设备访问特定的设备初始化信息,并将其放置在预定义的缓冲区中。 这些访问与其他启动任务并行发生。 加载设备驱动程序时,其初始化中的一些已经完成,从而缩短了启动系统所需的时间。
