ubuntu

先安装

环境变量

再安装下面的

sudo apt-get install g++

sudo apt-get install build-essential

sudo apt-get install libgtk2.0-dev

sudo apt-get install bison

sudo apt-get install libx11-dev libxrandr-dev libsdl1.2-dev vgabios

sudo apt-get install xorg-dev 

bochs -version就可以了

接下来按照这个文档跑

bochs安装配置_哔哩哔哩_bilibili

上面video也是按照这个步骤

virturlbox

enable the Shared Clipboard and install the VirtualBox Guest Additions. [1, 2]

Follow these steps to get it set up:

1. Enable Bidirectional Clipboard

2. Open VirtualBox and make sure your Ubuntu Virtual Machine (VM) is powered off.

3. Click on the VM and select Settings.

4. Go to the General tab, then click on the Advanced tab.

5. Set Shared Clipboard and Drag’n’Drop to Bidirectional.

Install VirtualBox Guest Additions

• Start your Ubuntu virtual machine.
• Once booted, go to the top menu bar of the VirtualBox window and click Devices > Insert Guest Additions CD Image.
• A prompt may appear asking you to run the software. If so, click Run and enter your password.
• If a CD icon appears on your Ubuntu desktop, right-click it and select Open in Terminal.
• Inside the terminal, run the installer by typing:
  sudo sh ./VBoxLinuxAdditions.run
• Enter your password and press Enter.
• Once the installation is complete, restart your Ubuntu VM. [1, 2, 3, 4, 5]

安装bochs

tar vxzf bochs-2.6.9.tar.gz

cd bochs-2.6.9

./configure --enable-debugger --enable-disasm
make
sudo make install

运行

mac也是

nasm boot.asm -o boot.bin
dd if=boot.bin of=a.img  bs=512 count=1

//输入bochs
bochs
c

此时bochs已经开始运行了，但是还是黑屏，还需要在终端输入c，此时软盘里还没有东西，所以会提示一个选项，点击continue ，才会开始启动模拟，如下图所示：

修改

xxd a.img > a.txt  

//创建软盘,再执行上面两行命令
bximage 
1

organe's一个操作系统实现实验一实验步骤_哔哩哔哩_bilibili

这个也需要修改
# filename of ROM images
romimage: file=/usr/local/share/bochs/BIOS-bochs-latest
vgaromimage: file=/usr/local/share/bochs/VGABIOS-lgpl-latest

# enable key mapping, using US layout as default.
for ubuntu
keyboard:  keymap=/usr/local/share/bochs/keymaps/x11-pc-us.map
for macos
keyboard: keymap=/usr/local/share/bochs/keymaps/sdl2-pc-us.map

macos

./configure --prefix=/usr/local \
--enable-smp \
--enable-cpu-level=6 \
--enable-disasm \
--enable-x86-64 \
--enable-vmx=2 \
--enable-svm \
--enable-all-optimizations \
--enable-debugger \
--enable-debugger-gui \
--with-sdl2

If SDL2 fails, try:
–with-sdl

Build

make

(This may take several minutes.)

Install

sudo make install

error

2) Find the line around ~194

You’ll see something like:

char *devname; ... if ((devname = strrchr(devpath, '/')) != NULL) {

3) Change devname to const char *

Edit it to:

const char *devname; ... if ((devname = strrchr(devpath, '/')) != NULL) {

保护模式

实验a运行

需要代码自带的 a.img,因为 pmtest1.asm 没有55aa,自己创建的找不到盘

nasm pmtest1.asm -o pmtest1.bin
dd if=pmtest1.bin of=a.img bs=512 count=1 conv=notrunc

实验b

nasm pmtest2.asm -o pmtest2.com

//macos
sudo mkdir /Users/m/Documents/floppy/
sudo mount -o loop pm.img /Users/m/Documents/floppy/
sudo cp pmtest2.com /Users/m/Documents/floppy/
sudo umount /Users/m/Documents/floppy/


//ubuntu

sudo mkdir /home/m/Documents/floppy/
sudo mount -o loop pm.img /home/m/Documents/floppy/
sudo cp pmtest2.com /home/m/Documents/floppy/
sudo umount /home/m/Documents/floppy


 sudo mkdir /mntfloppy
 nasm boot.asm -o boot.bin
 nasm loader.asm -o loader.bin
 dd if=boot.bin of=a.img bs=512 count=1 conv=notrunc 
 sudo mount -o loop a.img /mntfloppy/
 sudo cp loader.bin /mntfloppy/
 sudo umount /mntfloppy/


bochs
c
//运行模拟器后 到bochx 虚拟机，B磁盘下
b:
//运行
pmtest2.com

五内核

ld -m elf_i386 -s -o hello  hello.o

加载kernel

nasm boot.asm -o boot.bin
nasm loader.asm -o loader.bin
nasm -f elf kernel.asm -o kernel.o
ld -m elf_i386 -s  kernel.o -o kernel.bin 
dd if=boot.bin of=a.img bs=512 count=1 conv=notrunc 
sudo mkdir /mntfloppy
sudo mount -o loop a.img /mntfloppy/
sudo cp loader.bin /mntfloppy/
sudo cp kernel.bin /mntfloppy/
sudo umount /mntfloppy/
