;; 程序名: FDBOOT.ASM 程序版本: 0.04? 最后修定日期:2002.11.21 ;;
;; 程序主要功能: 在 PC DOS、DR DOS、MS DOS、Novell DOS、WINDOWS 9x 或者是 ;;
;; Windows Me 的命令行模式（即 DOS 模式）中运行本程序，程序通过检查软盘引导 ;;
;; 扇区内容是否被更改来判断数据软盘是否支持自动引导功能，若不支持则用修正的 ;;
;; 引导代码写入引导扇区中，使数据软磁盘支持自动引导功能。 ;;
;; 使用说明: 进入DOS模式后运行本程序，程序即自动完成数据软盘引导程序的制作。;;

欢迎大家提宝贵意见！谢谢！

佩服佩服！！！
怎学过来的？

第一个版本写于1995年，当时程序没有任务提示信息即更改A盘的引导区内容，后来有了英文的提示，再后来就能根据是否启动中文系统分别提示中英文信息了，不过程序的主要代码没有改变。我做此程序的目的就是为了在开机时再也不用将无引导功能的数据磁盘从软驱中拿出来了。但现在此程序存在的意思已经没有了，因为现在几乎已经没有几个人还用软驱了。我上传此程序只是为了和大家交流心得。

佩服佩服

精湛啊。佩服佩服

强，又是一个牛人
