其中READ、write 那个16进制是什么意思呀！还有后面的那个0 ，|| 这个是与的意思吗？还是并且执行的意思？
write --offset=200 (hd-1,0)/BAT/_ENV.BAT set PEISO=/0PE/0PE.ISO\r\n
cat --length=0 ()/BOOT/GRUB/GRUB.0PE && (hd-1,0)/BIN/FAT copy ()/BOOT/GRUB/GRUB.0PE (hd-1,0)/GRUBNEW.EXE || echo


好高深呀

十六进制涉及到了内存地址寻址问题  这个还是自己找相关的资料看吧  需要有点基础

||你可以理解为  a||b  命令a执行失败的话就执行命令b  a执行成功就不执行b

同类的还有&&  a&&b  命令a执行成功的话就执行命令b  a执行失败就不执行b

也可以看看http://bbs.wuyou.net/forum.php?mod=viewthread&tid=181347这里的几个实例教程  有别的高手解读的注释
