In my case my master microcode file resides in the rom module with GUID ‘17088572-377F-44EF-8F4E-B09FFF46A070’. Select the first microcode entry in the FIT table by doubling clicking item #2 as illustrated above and you will note that UEFITool A40 will automatically finds the actual master microcode file for us to manipulate. Then you have a number of references to the location of the actual microcode entries followed by possibly Bios initialization and ACM modules, Bootgaurd modules, and TPM/TXT modules of which may or may not be present depending on the bios. Take note that there will be a number of entries with the first one being a reference to ‘FIT’ table. In the meantime, it can be useful to users who want to extract or update the information inside a BIOS file.Load your bios file in UEFITool A57 and select the ‘FIT’ tab on the lower panel. In a nutshell, UEFITool makes quite an impression, although it’s still got a long way to reach the peak of its development.
Once you’re done with the editing part, you can export the image locally, for later use. The operations that you can carry out with UEFITool are various and make quite the list you can extract data from an image (or just the body) or you can insert items inside the structure of the image, as well as to insert or remove unwanted pieces. UEFITool is compatible with a variety of BIOS image types, including ROM, BIN, CAP, BIO, FD, WPH and EFI, which are loaded and displayed inside a structured view, alongside details such as name, type and subtype. The application sports an extremely simple design and is less impressive in terms of appearance the compromise it makes on looks is certainly compensated in functionality, if we look at the bigger picture.
