Description
Genfw is mainly used to process PE32 image to get the expected image data or image file. PE32 is a general-purpose image format that contains, among other information, data identifying the target environment for execution of the image. This utility can modify the standard PE32 image to create UEFI image with EFI subsystem type, PI Terse Executable image with the compact TE image header, zero its dubug data or reset its time stamp. It can also extract PE32 image data to create bin file, extract PE32 image data section to create Acpi table image, or dump PI TE image header information. It can also parse the text MicroCode definition file to create the MicroCode binary image, merge (concatenate) several MicroCode binary images into a single file by pad value and alignment requirement. This tool also supports the override the input file with the output contents.
