Abstract:
1. A method for managing boot trace information, comprising: configuring a host bus adapter for collecting boot trace information for a plurality of modules during a boot operation; wherein the plurality of modules include basic input and output system (BIOS) code, extended firmware interface code (EFI) and a host bus adapter driver executed by the host system; wherein a utility module sets a level for each of the plurality of modules based on which boot trace information for each of the plurality of modules is collected; enabling boot trace collection in the host bus adapter, wherein the utility module enables boot trace collection for the plurality of modules; saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if hardware initialization fails; saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if host bus adapter firmware loading is unacceptable; saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if a BIOS host system initialization is unacceptable; and saving boot trace information in a designated area of the non-volatile memory of the host bus adapter, if target discovery is improper.
