5、如何防止DOS引导扇区数据丢失在格式化后,安装系统软件和应用软件前及时保存DOS引导扇区数据,同样不失为一种良好的维护习惯。DOS引导区数据破坏同样也可以造成机器无法启动机器现象,这样可避免重新制作硬盘和安装大量软件而浪费时间。其保存方法可利用DEBUG程序来完成,应熟记这个操作步骤:C>DEBUG ;说明-A 400 ;增加命令MOV AX,0201 ;02->物理磁盘读操作,01->读一个扇区MOV BX,0100 ;0100->读数据的存放地址MOV CX,0001 :00->起始柱面号,
5, how to prevent DOS boot sector data loss After formatting, install the system software and application software to save the DOS boot sector data in time, the same is a good maintenance habits. DOS boot area data corruption can also cause the machine can not start the machine phenomenon, so as to avoid re-making the hard disk and installing a lot of software and a waste of time. The save method can use DEBUG program to complete, should remember this step: C> DEBUG; Description -A 400; Add command MOV AX, 0201; 02-> Physical disk read, 01-> Read a sector MOV BX , 0100; 0100-> Read data storage address MOV CX, 0001: 00-> starting cylinder number,
