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。

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

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本回答被网友采纳

尼的结合程序和电路才好理解啊
这样但看难明白的

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
