摘要： A pre-boot loader reduces the boot time of an operating system (OS). An OS is typically loaded by its own OS loader. A pre-boot loader is typically a software module in the system firmware or the pre-boot environment that loads the OS loader, which in turn loads the OS. In one embodiment, the pre-boot loader bypasses part or all of the steps performed by the OS loader, which shortens the loading time of the OS loader and the OS. In another embodiment, bypassing the steps of the OS loader reduces dependency on the system firmware functions. The system firmware takes advantage of this to further reduce boot time, by executing the pre-boot loader earlier instead of waiting until the full completion of system initialization by the system firmware.

摘要翻译： 预引导加载程序可以减少操作系统（OS）的启动时间。 OS通常由其自己的OS加载程序加载。 预引导加载程序通常是系统固件或预引导环境中的软件模块，用于加载OS加载程序，OS加载程序又会加载操作系统。 在一个实施例中，预引导加载器绕过由OS加载器执行的部分或全部步骤，这缩短了OS加载器和OS的加载时间。 在另一个实施例中，绕过OS加载器的步骤减少对系统固件功能的依赖性。 通过执行预引导加载程序，而不是等到系统固件完全完成系统初始化之前，系统固件利用此功能来进一步减少启动时间。
