Abstract
Systems and methods are disclosed for an initialization process that selectively reloads part or all of the UEFI when called by the operating system. The reload skips platform initialization and enables the selective loading of UEFI modules with tailored dependencies. A special protected region of memory is reserved and is not available for use by the host operating system. Once initialized, the UEFI will use the reserved memory region to execute code that initiates or loads UEFI modules. The host operating system will await the UEFI reload and then re-initialize the functions, structures and variables it receives from the UEFI.
