ABSTRACT:
An embodiment of the present invention bridges event data from the pre-boot environment to the operating system runtime environment. Event logs are stored in a memory buffer during pre-boot. Prior to launching the operating system (OS), the event log is registered to a known memory location accessible to the OS. A preferred embodiment uses the extensible firmware interface (EFI) configuration table to store the event log. A globally unique identifier (GUID) may be used to identify the memory buffer location. Once accessible to the OS, the event data may be displayed using standard extensible Markup Language (XML) forms, or via any other desired method.
