制作USB版的Debian
到网站http://debian-live.alioth.debian.org/下载for usb的debian-live-501-i386-xfce-desktop.img文件
模拟运行:
qemu-system-x86_64 -hda debian-live-501-i386-xfce-desktop.img
查看文件内容:
1)先获取偏移值
使用fdisk来看每个分区的起始逻辑扇区号，扇区号乘以512就是我们所要的偏移值。此处只有一个分区，偏移值为:
offset = 63 x 512 = 32256(byte)
fdisk -ul debian-live-501-i386-xfce-desktop.img
得到以下内容:
