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.
