Bochs上运行BIOS启动代码

       安装好了Bochs，也运行了Demo系统没有问题。测试自己的BIOS启动代码的时候却一直不成功。最初，我以为这是我的镜像文件制作错了，花了整个晚上折腾镜像文件还是没有成功。于是又尝试修改启动配置文件，启动配置文件修改了之后依然不成功。睡眼惺忪的时候看了一眼代码发现代码错了！真是醉了！

       配置文件如下：

# bochsrc.txt filefor DLX Linux disk image.

# enable keymapping, using US layout as default.

#

# NOTE: In Bochs1.4, keyboard mapping is only 100% implemented on X windows.

# However, the keymapping tables are used in the paste function, so

# in the DLX Linuxexample I'm enabling keyboard_mapping so that paste

# will work.  Cut&Paste is currently implemented onwin32 and X windows only.

 

keyboard:keymap=D:\software\Bochs-2.6.9\keymaps\x11-pc-us.map

#keyboard:keymap=../keymaps/x11-pc-fr.map

#keyboard:keymap=../keymaps/x11-pc-de.map

#keyboard:keymap=../keymaps/x11-pc-es.map

       启动之后的效果：

       终于看到了红色的启动提示字符，感觉终于有了一点成就感。其实，这个启动的配置文件写起来十分简单，最简单的方式自然还是使用dd命令。感觉Win10支持bash之后，折腾各种东西的时候都十分顺手啊！
