Abstract
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.
