1、下载安装bochs……（这步不会的下面可以不用看了……）
2、在Bochs安装目录中创建一个WinXP文件夹（同上面的括号）
3、创建虚拟硬盘用于存放WinXP镜像
具体步骤：
进入命令提示符，使用bximage工具
生成image需要回答几个问题
一：生成硬盘还是软盘
二：镜像类型 flat sparse or growing
三：镜像大小：WinXP一般5GB足够了
四：镜像名称：这个按照您个人的喜好吧
请注意！最后会要求你复制下面一行虚拟硬盘的参数，一定要复制下来，
否则一旦cmd退出，这些参数很难找回来
下面给出我用Bximage创建虚拟硬盘的范例
C:Program FilesBochs-2.4.5>bximage

Disk Image Creation Tool for Bochs
$Id: bximage.c,v 1.34 2009/04/14 09:45:22 sshwarts Exp $
========================================================================
Do you want to create a floppy disk image or a hard disk image?
Please type hd or fd. [hd] hd
What kind of image should I create?
Please type flat, sparse or growing. [flat] flat
Enter the hard disk size in megabytes, between 1 and 129023
[10] 5000
I will create a 'flat' hard disk image with
cyl=10158
heads=16
sectors per track=63
total sectors=10239264
total size=4999.64 megabytes
What should I name the image?
[c.img] winxp.img
Writing: [] Done.
I wrote 5242503168 bytes to winxp.img.
The following line should appear in your bochsrc:
ata0-master: type=disk, path="winxp.img", mode=flat, cylinders=10158, heads=16
, spt=63
(The line is stored in your windows clipboard, use CTRL-V to paste)
Press any key to continue
（粗体为需要输入的数据）
过程很简单
之后将安装目录下生成的img文件移动到你创建的文件夹中
4、下面就是配置WinXP虚拟机参数，
具体步骤
从bochs安装目录的dlxlinux复制出bochsrc.bxrc
用记事本打开编辑
############IMPORTANT##############
cpu: count=1, ips=10000000, reset_on_triple_fault=1, ignore_bad_msrs=1

##############此处改为256（内存大小，你可以根据你自己的需要修改，不过建议最好不要低于256M）
# filename of ROM images
romimage: file=BIOS-bochs-latest
vgaromimage: file=VGABIOS-lgpl-latest
###########我将BIOS-bochs-latest 和VGABIOS-lgpl-latest 复制到了我创建的文件夹中，于是去掉了"../"

# enable key mapping, using US layout as default.
#
# NOTE: In Bochs 1.4, keyboard mapping is only 100% implemented on X windows.
# However, the key mapping tables are used in the paste function, so
# in the DLX Linux example I'm enabling keyboard_mapping so that paste
# will work. Cut&Paste is currently implemented on win32 and X windows only.
