終端中編譯：

nasm boot.asm -o boot.bin

1.4 用 bochs 生成軟盤

終端輸入

bximage

操作如下：

ubuntu@ubuntu:~/coos$ bximage ======================================================================== bximage Disk Image Creation / Conversion / Resize and Commit Tool for Bochs $Id: bximage.cc 13069 2017-02-12 16:51:52Z vruppert $ ======================================================================== 1.

將引導扇區寫進軟盤：

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

再編寫 bochsrc 配置

//bochsrc #configuration file foe bochs #how much memory the emulated machine will have megs: 32 #filename of ROM images romimage:file=/home/ubuntu/bochs-2.6.9/bios/BIOS-bochs-latest # 這個文件需要自己在電腦里找 vgaromimage:file=/home/ubuntu/bochs-2.6.9/bios/VGABIOS-lgpl-latest # 這個文件需要自己在電腦里找 #what disk images will be used floppya:1_44=a.img,status=inserted #choose he boot disk boot:floppy #where do we send log messages log:bochsout.txt #disable the mouse mouse:enabled=0 #enable key mapping,using US layout as default keyboard:keymap=/home/ubuntu/bochs-2.6.9/gui/keymaps/x11-pc-us.map
