以ubuntu操作系统为例
一、命令行安装
sudo apt-get install vgabios bochs bochs-x bximage
此方法方便,不过都说这个方法安装的bochs没有调试功能,所以我没有尝试,有时间再补充验证吧
二、源码安装
1. 源码下载
直接下载当前最新的源码,准备在linux上安装,所以下载的 bochs-2.6.9.tar.gz
2. 安装前准备
sudo apt-get install build-essential xorg-dev libgtk2.0-dev bison
省掉config过程很多依赖编译报错
3. 编译安装
sudo tar xvzf bochs-2.6.9.tar.gz
cd bochs-2.6.9
./configure --enable-debugger --enable-disasm --enable-readline -LIBS='lx11'
make
sudo make install
make install 会把bochs可执行文件拷贝到/usr/local/bin/目录下
重启linux或者让环境变量重新生效,可以直接在当前目录下调用bochs
4. 修改bochsrc配置文件
在bochs-2.6.9目录下,有一个配置文件 .bochsrc,我们需要修改,让他运行我们的a.img
#cpu: model=core2_penryn_t9600, count=1, ips=50000000, reset_on_triple_fault=1, ignore_bad_msrs=1, msrs="msrs.def" cpu: model=amd_k6_2_chomper, count=1, ips=50000000, reset_on_triple_fault=1, ignore_bad_msrs=1, msrs="msrs.def" cpu: cpuid_limit_winnt=0 memory: guest=512, host=256 romimage: file=$BXSHARE/BIOS-bochs-latest, options=fastboot vgaromimage: file=$BXSHARE/VGABIOS-lgpl-latest mouse: enabled=0 pci: enabled=1, chipset=i440fx private_colormap: enabled=0 #floppya: 1_44=/dev/fd0, status=inserted #floppya: image=../1.44, status=inserted #floppya: 1_44=/dev/fd0H1440, status=inserted #floppya: 1_2=../1_2, status=inserted #floppya: 1_44=a:, status=inserted floppya: 1_44=a.img, status=inserted, write_protected=1 #floppya: 1_44=/dev/rfd0a, status=inserted ata0: enabled=1, ioaddr1=0x1f0, ioaddr2=0x3f0, irq=14 ata1: enabled=1, ioaddr1=0x170, ioaddr2=0x370, irq=15 ata2: enabled=0, ioaddr1=0x1e8, ioaddr2=0x3e0, irq=11 ata3: enabled=0, ioaddr1=0x168, ioaddr2=0x360, irq=9 #ata0-master: type=disk, mode=flat, path="30M.sample" #ata0-master: type=disk, mode=flat, path="30M.sample", cylinders=615, heads=6, spt=17 #ata0-master: type=disk, mode=flat, path="c.img", cylinders=0 # autodetect #ata0-slave: type=disk, mode=vvfat, path=/bochs/images/vvfat, journal=vvfat.redolog #ata0-slave: type=cdrom, path=D:, status=inserted #ata0-slave: type=cdrom, path=/dev/cdrom, status=inserted #ata0-slave: type=cdrom, path="drive", status=inserted #ata0-slave: type=cdrom, path=/dev/rcd0d, status=inserted boot: floppy #boot: disk floppy_bootsig_check: disabled=0 log: bochsout.txt panic: action=ask error: action=report info: action=report debug: action=ignore, pci=report # report BX_DEBUG from module 'pci' debugger_log: - parport1: enabled=1, file="parport.out" #sound: driver=default, waveout=/dev/dsp. wavein=, midiout= #speaker: enabled=1, mode=sound
有注释的地方基本都是改动过的,解决了下一步启动运行过程中,几个问题
5. 启动运行bochs虚拟机
bochs -f .bochsrc
能到这一步,如果有问题,大部分都是bochsrc配置的问题,可以查看报错点,尝试注释掉,确保最基本的几个配置基本就可以正常运行了
例如:
memory: guest=512, host=256
romimage: file=$BXSHARE/BIOS-bochs-latest, options=fastboot
vgaromimage: file=$BXSHARE/VGABIOS-lgpl-latest
floppya: 1_44=a.img, status=inserted, write_protected=1
boot: floppy
启动过程可能遇到的问题:
问题1:.bochsrc:187: cpu directive malformed
解决方法:
linux终端下:bochs -help cpu
我的电脑是AMD处理器,我就选amd_k6_2_chomper
修改配置文件即可
#cpu: model=core2_penryn_t9600, count=1, ips=50000000, reset_on_triple_fault=1, ignore_bad_msrs=1, msrs="msrs.def" cpu: model=amd_k6_2_chomper, count=1, ips=50000000, reset_on_triple_fault=1, ignore_bad_msrs=1, msrs="msrs.def"
问题2:.bochsrc:915: Bochs is not compiled with lowlevel sound support
解决方法:修改配置文件,注释掉以下两行
#sound: driver=default, waveout=/dev/dsp. wavein=, midiout=
#speaker: enabled=1, mode=sound
问题3:syntax error at 'dump_cpu'
解决方法:none
bochs 2.3.5 以上的版本没有dump_cpu了,可以用r,fp,mmx,sse,dreg,sreg,creg命令代替
