64位windows7使用debug的方法
(1)下载dos模拟器dosbox。
下载地址： http://www.dosbox.com/download.php?main=1(2)下载Windows 7 32位的debug程序。
下载地址：http://u.115.com/file/b3mmegwu，可以下载，也可以到安装了32位windows7的计算机上进行拷贝。
注意：进行下一步操作之前，必须先将下载的debug.exe先复制到分区D根目录下。如果童鞋们对于“文件路径”这个概念比较清楚，就不存在神马“必须”这样的说法了，你可以自由选择存放debug.exe以及汇编程序开发环境的位置，只需要在使用dosbox的mount命令是指定存放位置即可！mount命令的使用说明参见文末的参考资料。
(3)安装dosbox，完成以后，双击快捷方式进入dos界面。
(5)在命令提示符后输入mount c d:
(6)在命令提示符后接着输入c:
(7)接下来，就可以使用Debug了。
如果在使用debug跟踪、调试过程中出现找不到文件等问题，注意mount命令中指定的路径是否正确。

dosbox中mount命令的使用说明
MOUNT.COM is a command inside DOSBox that can connect physical folders and drives to virtual drives inside DOSBox. The mounted drive does not automatically refresh files changed out side of DOSBox. You can refresh these files on all mounted drives by activating the Swap Image event (Hot key: Ctrl F4) to have access to changed files automatically when, for example, the drive is mapped as a floppy.
When you enter the command MOUNT from the DOSBox prompt you should see:
Z:\>MOUNT Current mounted drives are: Drive Z is mounted as Internal Virtual Drive
To mount a folder as a drive, follow this basic template:
MOUNT [Drive-Letter] [Local-Directory]
The local directory can be specified relative to the working directory from which DOSBox was started.
To unmount a drive, follow this basic template:
MOUNT -u [Drive-Letter]
Usage Examples
Windows
Mounting the working directory from which DOSBox was started
Z:\>MOUNT C .
Mounting a specific folder from your hard drive
Z:\>MOUNT C C:\DOSGAMES
