操作系统的移植主要取决于cpu ,所以操作系统的移植基本都是大同小异。所以移植raw os 的时候最快的捷径是看看有没有其它os 移植到过上面，如果有的话移植会简单很多。-Portable operating system mainly depends on the CPU operating system, so the basic transplantation are similar. So the fastest way to transplant OS raw is to see if there are any other OS ported to it, and if any of the transplants will be much simpler.
