Abstract
Technologies are provided for generation of firmware configured to restrict use of a firmware tool. Some embodiments include a computing system that can obtain firmware source code comprising a module configured to copy contents of a digitally signed binary file to an advanced configuration and power management interface (ACPI) table at runtime of a firmware. The computing system can generate a firmware image of the firmware, the firmware image comprising the module, a first firmware globally unique identifier (GUID), and a defined area storing digital content that remains unchanged upon a change to the firmware. The computing system also can obtain a binary file comprising a second firmware GUID, a firmware tool GUID, and a feature GUID, and can digitally sign the binary file using a private encryption key to generate the digitally signed binary file. The computing system can store the digitally signed binary file within the defined area.
