2 安裝必要工具
$ sudo apt-get install vgabios bochs-x bximage bochs-sdl xorg-dev nasm bochsbios g++
3 編譯,安裝
編譯，安裝bochs.
$ sudo ./configure --enable-debugger --enable-disasm
$ sudo make
$ sudo make install
4 編寫程序，執行程序
a.編寫程序，命名為hello.asm:
org 07c00h
mov ax,cs
mov ds,ax
mov es,ax
call DispStr
jmp $
DispStr:
mov ax,Str
mov bp,ax
mov cx,13
mov ax,01301h
mov bx,000ch
mov dl,0
int 10h
ret
Str: db "hello world"
times 510-($-$$) db 0
dw 0xaa55
b.編譯程序
$ nasm hello.asm -o hello.bin
c.制作floppy文件
首先制作空test.img磁盤:
$ bximage

Please type hd or fd. [hd] fd
Choose the size of floppy disk image to create, in megabytes.
Please type 160k, 180k, 320k, 360k, 720k, 1.2M, 1.44M, 1.68M, 1.72M, or 2.88M.
[1.44M] 1.44M
What should be the name of the image?
[a.img] test.img
Creating floppy image 'test.img' with 2880 sectors
The following line should appear in your bochsrc:
floppya: image="test.img", status=inserted
$ dd if=hello.bin of=test.img bs=512 count=1 conv=notrunc
d.編寫bochsrc文件
bochsrc文件內容為:
megs:32
romimage:file=/usr/share/bochs/BIOS-bochs-latest
vgaromimage:file=/usr/share/bochs/VGABIOS-lgpl-latest
floppya:1_44=test.img,status=inserted
boot:floppy
mouse:enabled=0
keyboard:keymap=/usr/share/bochs/keymaps/x11-pc-us.map
e.執行:
$ bochs -f bochsrc
f.啟動成功，可以看到如下界面:

2 bochs操作系統測試
基于bochs，我們可以測試幾個操作系統，以便可以自己去寫一個操作系統，來熟悉x86結構。
1 MenuetOS
我也貼一張使用軟盤啟動后的界面：

2 ReactOS

關于該系統，可以在官網上下載，然后在vmware上進行安裝，我安裝后，體驗的系統效果如下圖所示：
