Help text

Create the bootable image as an EFI application that carries the actual kernel image in compressed form, and decompresses it into memory before executing it via LoadImage/StartImage EFI boot service calls. For compatibility with non-EFI loaders, the payload can be decompressed and executed by the loader as well, provided that the loader implements the decompression algorithm and that non-EFI boot is supported by the encapsulated image. (The compression algorithm used is described in the zboot image header)
