Abstract
Standard I/O library functions for accessing files stored on mass storage devices are modified to enable access to files stored in firmware volumes. An application can be compiled against the modified standard I/O library functions to generate a pre-boot application. When the pre-boot application is executed within a pre-boot execution environment, it can utilize standard I/O library functions to access files stored in a firmware volume. In response to receiving a request to open a file from a pre-boot application, the called I/O function searches a file cross-reference table to locate the filename for the file. If the filename is in the file cross-reference table, the GUID associated with the filename is retrieved from the file cross-reference table and used to obtain a file handle to the file. The file handle can then be returned to the pre-boot application and used to perform other types of operations on the file.
