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。
