Abstract
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.
