2 安装必要工具

$ sudo apt-get install vgabios bochs-x bximage bochs-sdl xorg-dev nasm bochsbios g++

3 编译,安装

编译，安装bochs.

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

4 编写程序，执行程序

a.编写程序，命名为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.编译程序

$ nasm hello.asm -o hello.bin

c.制作floppy文件
首先制作空test.img磁盘:

$ bximage
bximage

  Disk Image Creation / Conversion / Resize and Commit Tool for Bochs
         $Id: bximage.cc 12690 2015-03-20 18:01:52Z vruppert $
========================================================================

1. Create new floppy or hard disk image
2. Convert hard disk image to other format (mode)
3. Resize hard disk image
4. Commit 'undoable' redolog to base image
5. Disk image info

0. Quit

Please choose one [0] 1

Create image

Do you want to create a floppy disk image or a hard disk image?
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.编写bochsrc文件

bochsrc文件内容为:

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.执行:
