### Windows安装WSL

用管理权限打开Powershell

```shell
# 安装WSL
wsl --install

# 进入linux系统
wsl 

# WSL访问win C盘
cd /mnt/c
#win访问WSL home
explorer.exe

```



### ubuntu安装bochs

```shell
sudo apt install bochs bochs-x
# 启动bochs，验证是否安装成功
bochs 
bochs-x
```

源码安装

下载网址：https://sourceforge.net/projects/bochs/files/bochs/

```shell
tar -zxvf bochs-2.8.tar.gz
cd bochs-2.8
./configure --prefix=/home/shun/work/library/bochs-2.8/output --enable-debugger --enable-disasm --enable-iodebug --enable-x86-debugger --with-x --with-x11
make -j8
make install
```

创建镜像文件

```shell
./bximage
```

创建bochsrc

```shell
# how much memory the emulated machine will have
megs: 32

# filename for ROM images
romimage: file=/home/shun/work/library/bochs-2.8/output/share/bochs/BIOS-bochs-latest
vgaromimage: file=/home/shun/work/library/bochs-2.8/output/share/bochs/VGABIOS-lgpl-latest 

# what disk images will be used
floppya: image="/home/shun/work/library/bochs-2.8/output/bin/f.img", status=inserted

# choose the boot disk
boot: floppy

# where do we send log messages
log: bochsout_floppy.txt

# disable the mouse
mouse: enabled=0

# enable key mapping, using US layout as default
keyboard: keymap=/home/shun/work/library/bochs-2.8/output/share/bochs/keymaps/x11-pc-us.map
```

启动bochs

```shell
./bochs -f bochsrc
```

### ubuntu安装QEMU

```shell
sudo apt update
sudo apt install qemu qemu-kvm libvirt-daemon libvirt-clients bridge-utils virt-manager

qemu-system-x86_64 -version

# 启动
virt-manager
```

### bootsect.S

```shell
as -o bootsect.o bootsect.S
# -Ttext 0x0 将目标文件bootsect.O的代码段放到linux.img的开头，即第一扇区
ld -m elf_x86_64 -Ttext 0x0 -s --oformat binary -o linux.img bootsect.o
```

用qemu运行

```shell
qemu-system-i386 -boot a -fda linux.img 
```



bootsect.S
