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.

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.

Abstract: Examples of electronic devices are described herein. In some examples, an electronic device includes a flash memory. In some examples, the electronic device includes a host memory to store an access control structure to access the flash memory. In some examples, the electronic device includes a first circuitry coupled to the host memory and the flash memory. In some examples, the first circuitry is to read the access control structure in the host memory to determine when to access the flash memory.

Abstract: Examples associated with password updates are described. One example method includes receiving a request to modify an administrator password in a basic input/output system (BIOS). The administrator password may be updated. A first password tied to the administrator password may be identified. A first updated password is generated by concatenating a character string to the administrator password. The character string may be generated based on a password policy for the first password. The first password may then be updated to the first updated password.

Abstract: A storage may store machine-readable instructions for execution by a processor. Execution of the machine-readable instructions may cause the processor to receive an update capsule via a firmware update interface. The update capsule may include a device identifier and a payload. The payload may include data that is different from a firmware update. Execution of the machine-readable instructions may cause the processor to execute a virtual device handler, based on the device identifier, to process the payload.

Abstract: In example implementations, an apparatus is provided. The apparatus includes a controller, a memory protection policy, an electrically isolated memory, and a non-volatile memory. The memory protection policy includes an allowable write function. The electrically isolated memory is to store code executable by the controller to execute a requested write function based on the set of memory protections. The non-volatile memory is in communication with the controller. The requested write function is to be executed in the non-volatile memory when the requested write function matches the allowable write function.

Abstract: An authentication system is disclosed herein. An example includes a computing device and a port associated with the computing device for connection of an accessory to the computing device. The example also includes an authentication device that generates an accessory response upon receipt of a challenge and a hardware controller. The hardware controller generates both the challenge and an expected response to the challenge. It compares the expected response to the accessory response to ascertain if the accessory response is one of a valid response and an invalid response, and it signals for the port to be enabled for the valid response to allow access to functionality of the accessory by the computing device. Other features and components of the authentication system are also disclosed herein, as is a method of authenticating an accessory for use by a computing device.

Abstract: A computing device includes a storage device storing an operating system, and a secure storage device storing previously user-provided configuration information for the operating system, a username, and a security token. The computing device includes a processor, and a memory storing instructions executable by the processor. The instructions are executable to, at first user power-on of the computing device, automatically configure the operating system according to the previously user-provided configuration information so that the operating system is configured without manual user input at the computing device. The instructions are executable to automatically register the operating system with the username and with the security token as a single-use password without user interaction.

Abstract: An example electronic device includes a storage circuit, a central processing unit (CPU) coupled to the storage circuit, and a controller coupled to the storage circuit. The CPU is to receive a Basic Input/Output System (BIOS) update image for the electronic device, verify a signature of the BIOS update image, and responsive to verification of the BIOS update image, store a portion of the BIOS update image in the storage circuit. The controller is to obtain the portion of the BIOS update image from the storage circuit, and program the portion of the BIOS update image to a BIOS component of the electronic device.
