Upon completion of the editing process, you can easily export the image. UEFITool will permit you to extract data from an image, insert items within the structure of the image, and insert or remove unwanted pieces as needed. It supports full BIOS image parsing, including the flash descriptor or any binary files containing UEFI volumes it is compatible with multiple BIOS image types, including ROM, BIN, FD, CAP, BIO, WPH, and EFI, all of which will be conveniently loaded and displayed alongside pertinent details including name, type/subtype, and text for example. UEFITool allows the modification, parsing, and extraction of UEFI firmware images. Unified Extensible Firmware Interface or UEFI is a post-BIOS firmware specification originally written by Intel for Itanium architecture and than adapted for X86 systems. AMI-specific features like NCBs, ROM_AREA structure and other things like that can't be implemented by me because of the NDA I have.Tool to modify, parse, and extract UEFI firmware.If someone wants to write an unpacker for such crappy files - I will be glad to use it. The program is meant to work with BIOS images, not some vendor-specific BIOS update files, that is why some of that update file either cant be opened at all or return errors on reconstruction.It's on my high priority features list, so I hope it will be corrected soon. Some images may not work after modification because of no FIT table support implemented yet.Some images has non-standard calculation of base address of TE images, so the program can rebase them incorrectly after modifications.Don't rush it, because reconstruction process can also generate some usefull messages, which will be lost if you open the reconstructed file immediatelly. If anything goes wrong on the reconstruction, an error will pop up, otherwise the program will prompt if you need to open the reconstructed file. After you've finished the modifications, you need to initiate image reconstruction using Save image file command from the File menu.
