Module Name:\r

    SecFixup.c\r
\r
Abstract:\r
\r
    This utility is part of build process for IA32 SEC FFS file.\r
    \r
    It fixup the reset vector data. The reset vector data binary file\r
    will be wrapped as a RAW section and be located immediately after\r
    the PE/TE section.\r
\r
    The SEC EXE file can be either PE or TE file.\r
