利用bochs来调试Linux 0.11内核

qtview

实验前的准备：
引导程序调试软件bochs,跟配套的linux0.11内核img下载地址分别是：
http://sourceforge.net/projects/bochs/
http://www.oldlinux.org/Linux.old/bochs/linux-0.11-devel-040329.zip
调试环境的的建立
下载linux-0.11-devel-040329.zip，解压缩
其中包含一个bochs2.X的安装程序和linux内核img，
1 、找到bochsrc-hd.bxrc文件的12、36行，替换其中的$ BXSHARE为bochs的安装路径，如果就是上级目录，则可直接改为“..”，如：
#romimage: file=$BXSHAREBIOS-bochs-latest, address=0xf0000
romimage: file=..bochsBochs-2.3BIOS-bochs-latest, address=0xf0000
2 、在添加run.bat文件，内容为：
"..bochsBochs-2.3bochsdbg" -q -f bochsrc-Hd.bxrc
运行run.bat，即启动调试工具bochsdbg。
调试
run.bat运行之后
E:linux011linux-0.11-devel-040329>"..bochsBochs-2.3bochsdbg" -q -f bochsrc-Hd.bxrc
