运行环境1:  XP  (vmware虚拟机),  3.5 软盘, DOS系统没有安装,不知道有没有问题
            2:虚拟机软盘驱动器,连接,随便生成1.fld或1.img格式的文件就可以了
            (这是把3.5软盘连接的,如果没有连接3.5软盘,那就没有效果的)
            3:在虚拟机编译后,直接运行就可以了,不过360报木马,点允许
         4:重启后就可以看到

代码如下:

;键盘输入1,2,3,4
;1) reset pc ;重新启动计算机
;2) start systme ; 引导现有的操作系统
;3) clock ; 进入动时钟程序,F1键修改颜色，退出ESC键
;4) set clock ; 设置时间,退出ESC键，设置时间Enter（回车键）

不懂你说的是什么意思?
这代码就是按照王爽汇编的书做课程设计!

呵呵，我以为你们的专业课的课程设计做关于汇编的~

cyousui · 发表于 2011-10-21 16:48:33

写入fld或img代码：

#include <stdio.h>
#include <fcntl.h>
#include <sys/types.h>
#include <sys/stat.h>

int main(int agrc,char *argv[])
{
int fd_source;
int fd_dest;
int read_count = 0;
char buffer[512] = { 0 };
fd_source = open("boot.bin",O_RDONLY);
if(fd_source < 0)
{
perror("open boot.bin error:");
return 0;
}
fd_dest = open("virtual_floppy.vfd",O_WRONLY);
if(fd_dest < 0)
{
perror("open virtual_floppy.vfd error:");
return 0;
}
while((read_count = read(fd_source,buffer,512)) > 0)
{
write(fd_dest,buffer,read_count);
memset(buffer,0,512);
}
printf("write image ok!\n");
return 0;
}

怎么把代码写到fld或img里？

你误会我的意思了,
虚拟机→移除设备→软盘驱动器→设置→使用软盘镜像文件→浏览,这里新建一个.fld或.img或.iso文件,
随便创建一个.txt文件然后把.txt改成上面3种格式,然后连接
然后代码就在虚拟机里面编译运行,
你打开(我的电脑)看看,除了c盘.d盘.e盘,f盘,h盘,还有没有3.5软盘
如果没有3.5软盘,那就不行了
这代码只在XP系统通过,或dos系统,

??

创建一个文件是要你虚拟机软盘驱动器连接，
---------------------------------------------------------
代码在虚拟机用编译器masn5 或6.15编译。在虚拟机里运行！
可能是我表达能力不好，我发我QQ号给你！加好友说吧
---------------
是把软盘X道X面X扇门的内容读取到0:7c00,再把CS:IP指向0:7c00,就可以执行引导程序
-----------------------
如果在0号软盘中没有软盘,
( 为了不出现这情况,就要"虚拟机软盘驱动器"连接,那就是生成.flp格式连接,如果你不连接的,那就写入不了软盘)

如果没有软盘,就读取C盘0道0面1扇门的内容到0:7c00,再把CS:IP指向0:7c00,执行原来的系统启动程序
