windowsCE镜像文件结构

Formats:

struct BinFile{

    BYTE signature[7];     // = { 'B', '0', '0', '0', 'F', 'F', '\a' }

    DWORD   ImageStart

    DWORD   ImageLength

    Record  ImageRecords[RecordNum]

  };

struct Record{

    DWORD address;

    DWORD length;

    DWORD chksum;

  };

在文件的最开端，会放置一个BinFile结构，imageStart和ImageLength分别对应镜像展开后在内存中存放的首地址和长度。该结构中的RecordNum为不确定的，通常在最后一个记录之后增加一个address和Chksum都为0的纪录表示结束，而这个表示结束的结构中的Length则标示其实际入口点。
