Abstract: Disclosed is a system and associated methods for cryptographically verifying a user of a computing device at the bootloader level and before the loading of an operating system (OS). The cryptographic verification involves loading a boot authentication controller into a memory of the computing device upon powering on the computing device. The boot authentication controller restricts access to the computing device by preventing an OS from being loaded into the memory during the boot process. The boot authentication controller determines a level-of-access that a particular user has on the computing device from a received encoded value, customizes the OS with the level-of-access specified in the encoded value, and boots the computing system with a customized OS that provides the level-of-access.

Abstract: Systems and methods for cross operating environment diagnostic operations with context resume. An Information Handling System (IHS) includes a processor and a memory coupled to the processor. The memory stores program instructions that, upon execution, cause the IHS to receive a command at a Basic Input/Output System (BIOS) from an Embedded Controller (EC) to perform a deep scan diagnostic operation. The command is received in response to a request by a host Operating System (OS) application. The BIOS executes the deep scan diagnostic operation and stores the result in an Advanced Configuration and Power Interface (ACPI) table. The host OS retrieves the result from the ACPI table and validates the result. The system enables comprehensive diagnostics by leveraging the BIOS environment, ensuring seamless context resume.
