  • Patent number: 12130926
    Abstract: Examples of electronic devices are described herein. In some examples, an electronic device includes a memory and a controller. In some examples, the controller is to enable a basic input/output system (BIOS) safe mode in response to an authentication procedure. In some examples, the controller is to provide access to back-up variable service region in the memory storing default BIOS data. In some examples, the controller is to start a modified BIOS based on the default BIOS data in response to enablement of the BIOS safe mode.
    Type: Grant

  • Publication number: 20220129198
    Abstract: An example apparatus is provided. The example apparatus includes a component controller. The example apparatus includes a memory storage device associated with the component controller to store volatile data from the component controller and to store non-volatile data from the component controller in separate blocks of memory. The volatile data and the non-volatile data are to operate the component controller. The example apparatus also includes a memory controller in communication with the component controller and the memory storage device to write the volatile data from the component controller to the memory storage device. In addition, the example apparatus includes a central processor in communication with the memory storage device. The central processor is to execute a firmware variable service. The central processor is to receive the non-volatile data from the component controller. The non-volatile data is to be written to the memory storage device by the firmware variable service.
