DOS下逻辑锁 首先，大略介绍一下我的程序，我是用汇编写成，程序有2个文件：hdlock.exe hdlock.dat ,其中hdlock.dat是我写的用于装入硬盘0柱0道1扇的硬盘锁,hdlock.exe实现 （1）把hdlock.dat装入硬盘0柱0道1扇并设置硬盘锁的密码，（2）修改密码，（3）卸载 硬盘锁 在此，先介绍一下 hdlock.dat，因为硬盘锁本身受空间限制，必须严格控制在1bdH 字节内，（知道为什么吗？）所以是不能用masm先写原程序，再编译，我基本上是用debug 的A命令一次性写出来的，我把这些反汇编了出来，加上一些注释，给大家看看，互相学习 吗。　-DOS logic lock First, I briefly tell us about the procedure that I used the compilation of written procedures are two documents : hdlock.exe hdlock.dat, hdlock.dat yes, I wrote for the packed column drives 0 0 1 hard disk lock, hdlock.exe achieve ( 1) hdlock.dat loaded drive 0- 0 and set up a password lock drive, (2) to alter the code, (3) remove the hard disk lock, first tell us about hdlock.dat, since drive lock itself subject to space restrictions, must be strictly controlled within the 1bdH byte (wonder why?) So it is not used can write original program first and then build, basically, I used the debug A one-time write down orders, I put out a compilation of the anti-plus some notes, for every
