<p>按照 win10-c-sysprep.yaml 安装好windows 10 后，再使用此配置重新配置操作系统，此会自动登录，并且执行登录后的启动脚本。<br> 注意：<br> （1）第一次用此yaml安装，要配置系统，较慢。以后启动很快。<br> （2）上面的登录后启动脚本，mount nfs服务，需要在启动系统，打开windows10 nfs客户端功能后，再放开注释</p>

<div>汇编语言编程入门：从环境搭建到简单程序实现1.数据存储介质问题解决在处理数据存储时，若要使用MEPIS系统，需确保有其可访问的存储介质。目前，MEPIS无法向采用NTFS格式（常用于Windows2000和XP工作站）的硬盘写入数据。不过，若硬盘采用FAT32格式，MEPIS就能进行写入操作。此外，MEPIS还能将文件写入软盘和大多数USB闪存驱动器。若工作站连接到局域网，还可通过FTP协议或挂载</div>

<div>从jdk1.5开始，java增加了enum(枚举)这个类型，但是大家在平时运用中还是比较少用到枚举的，而且很多人和我一样对枚举一知半解，下面就跟大家一起学习下enmu枚举。先看一个最简单的枚举类型，一个返回类型的枚举：
