make os for fun:hello,my first os!
郑重声明：此系列是本人阅读《Orange's System：一个操作系统的实现》（作者是于渊先生）的同时所作，本人是初学者，对于本书作者于渊先生十分的敬仰，文章只是涉及到一些书中以及自己做的实验同时附上自己的感悟，关于实验中的原理系统知识等，强烈建议购买原书进行进一步的研究学习！
My input program failed,i think my computer will follow it away,so before they make an appointment i will write in english.because i couldn't write my blog in "da jia hao,ni men kan de ming bai ma,zhe yang gan jue guai guai de?"

All i want to say is:''i love it as my grilfriend,e,actually second"',let's try it.
