1.编写程序hello.asm

mov ax, 0x10fe
jmp $
times 510 - ($ - $$) db 0
db 0x55
db 0xaa

2.编译程序 hello.bin

nasm hello.asm -o hello.bin

3.创建软盘

bximage hello.img

4.刻录程序

dd if=hello.bin of=hello.img bs=512 count=1 conv=notrunc

5.修改bochsrc.bxrc

# 修改一---修改images路径
# filename of ROM images
romimage: file="G:\Bochs-2.6.11\BIOS-bochs-latest"
vgaromimage: file="G:\Bochs-2.6.11\VGABIOS-lgpl-latest"

# 修改二---把硬盘都注释了
# hard disk
# ata0: enabled=1, ioaddr1=0x1f0, ioaddr2=0x3f0, irq=14
# ata0-master: type=disk, path="hd10meg.img", cylinders=306, heads=4, spt=17

#修改三---使用软盘
# choose the boot disk.
boot: floppy

#修改四---修改keyboard路径
keyboard: keymap="G:\Bochs-2.6.11\keymaps\x11-pc-us.map"

将修改的bochsrc.bxrc文件放入该程序目录下

6.启动虚拟机

bochsdbg -f bochsrc.bxrc
