汇编语言差不多 10 年没去接触了，都忘光了，不过看到这 55AA我仍然眼睛发亮，当时研究 MBR 时，发现最后两个字节也是 55AA，后来查阅过一些资料，BIOS 中每个块代码的结束处都是 55AA，于是知道 55AA 是块结束标志。

好像记得 DB （Define Bytes）是用来定义字节流吧

这个是定义的一些字节数据，在程序里面需要调用的，程序调用这些数据是随机的

用汇编也可以处理，一楼的方法也是一种。如果用c语言编程，无非就是把16位数分成两部分，高8位与低8位，在运算的时候，按照我们一般的规则，从低位开始先乘后加。编程序细致一点，问题不大。

55H是01010101，AA是10101010，这两个组合起来可以作为特殊字符，用于标记开始或者结束，当然，我印象最深的还是磁盘的0柱面0磁道0扇区的标志。

DB是字节后面那都是16位的数据地址还有别的提示吗好像是位地址
