Abstract: A method includes receiving a request from a protocol publisher to install a protocol at the protocol database, the request including a global unique identifier (GUID) and a first protocol pointer. The GUID and the first protocol pointer are stored at an entry at a protocol database. A root key received from the protocol publisher is stored at the entry at the protocol database. A request including the GUID is received from a protocol consumer, and in response, the protocol consumer is provided with a random number. A reference GUID is generated based on the random number and the root key, and the reference GUID is stored at the entry of the protocol database.

Abstract: A method includes creating, by system firmware at an information handling system, a virtual Advanced Configuration and Power Interface (ACPI) bus device. A management service event is registered by a bus device driver corresponding to the virtual ACPI bus device. The management service event, when executed, determines whether a target device is in a condition to receive revised firmware.

Abstract: A BIOS of an information may transmit information regarding events detected by the BIOS to an OS of an information handling system for logging in an OS event log. A BIOS of an information handling system may detect an event and may log information regarding the event in a memory of an information handling system. An OS of the information handling system may retrieve at least a portion of the information regarding the event from the event log and may add at least a portion of the retrieved information to an OS event viewer.

Abstract: A method includes receiving a basic input/output system (BIOS) update executable at an information handling system. The executable includes a BIOS image that is stored at system memory included at the information handling system. A boot sequence is initiated at the information handling system using the BIOS image stored at the system memory.

Abstract: A method includes receiving a firmware update package at an information handling system. The update package includes a payload containing a transition basic input-output system (BIOS) and another payload containing a new BIOS. The new BIOS is stored at an Extensible Firmware Interface system partition (ESP). A firmware image at a BIOS flash device at the information handling system is updated using the new BIOS retrieved from the ESP.

Abstract: A method includes receiving a basic input/output system (BIOS) update executable at an information handling system. The executable includes a BIOS image that is stored at system memory included at the information handling system. A boot sequence is initiated at the information handling system using the BIOS image stored at the system memory.

Abstract: Systems and methods for establishing Core Root of Trust Measurement (CRTM) for Basic Input/Output (BIOS) image recovery are described. In some embodiments, an Information Handling System (IHS) may include a processor and a BIOS coupled to the processor, the BIOS having program instructions that, upon execution, cause the IHS to: during a boot process, verify integrity of a BIOS recovery image using a CRTM, and determine whether to restore the BIOS recovery image in response to the verification.

Abstract: Methods and systems for license management using a basic input/output system (BIOS) may involve performing license activation, monitoring, and enforcement. The BIOS may store license information to manage licenses for hardware and/or software components of an information handling system. License management by the BIOS may include monitoring a system clock of the information handling system for changes to avoid tampering with license durations.

Abstract: In accordance with these and other embodiments of the present disclosure, a method may include determining whether a system management interrupt is expected to take more than a predetermined threshold duration to complete, determining whether audio data is actively streaming from a processor of an information handling system to an audio controller communicatively coupled to the processor and configured to process audio data communicated from the processor to the audio controller for reproduction to a speaker communicatively coupled to the audio controller, and executing the system management interrupt if the system management interrupt is expected to take less than a predetermined threshold duration to complete or if audio data is not actively streaming from the processor to the audio controller.

Abstract: A method for automatic correction of nonvolatile memory in information handling systems includes storing ECC data for a compressed BIOS firmware. The ECC data are used to identify and correct error bits in the compressed BIOS firmware. The discovered error bits are recorded in the nonvolatile memory and accessed for a faster correction method for the compressed BIOS firmware than using the ECC data on subsequent attempts.

Abstract: An information handling system operating a BMU controller may include a rechargeable battery, a BMU controller to determine battery charge percentage value, a memory device for storage of an internal data record indicating a first power-on setting, and the controller operatively coupled to the memory memory device and the rechargeable battery. The controller executing machine-readable executable code instructions to determine that the main memory contains no internal data record indicating a first power-on event and to limit the voltage received by the rechargeable battery such that percentage value of the charge of the rechargeable battery does not exceed a set percentage value charge limit during storage and shipment of the information handling system.
