NOT SUPPORTED BY LENOVO - USE AT YOUR OWN RISK

Yes, you can. Editing works with a .FD file (it can have another extension, for example ".ROM" o ".BIN").

For example, you can:

• Modify a logo.
• Modify EC.
• Modify a module.
• Insert a new module.
• Delete an existent module.
• Modify the microcode.
• Modify DMI structure.

After you finish editing, you have to save changes and flash the file.

Note: Flashing a modded EFI can void your warranty.
