硬盘主引导记录包括引导代码和分区信息 ,启动计算机时 ,ROMBIOS把主引导记录装入内存 ,并且把控制转给其引导代码的第一条指令 ,由此开始启动过程 ,引导代码通过读取分区表的引导标志来识别由哪一个分区引导系统 ,所以主引导记录的安全维护是非常重要的 为此 ,介绍一种新的保存和恢复主引导记录的方法 ,并且给出了一个用汇编语言编制的程序实例 The master boot record of the hard disk includes the boot code and partition information. When the computer is started, the ROMBIOS loads the master boot record into the memory, and transfers the control to the first instruction of the boot code, thereby starting the boot process and guiding the code by reading the partition Table boot logo to identify which partition to boot the system, so master boot record security maintenance is very important To this end, introduces a new method to save and restore the master boot record, and gives an assembly language Program instance
