Cisco 4013+TS引擎启动

做服务时碰见一问题,一共20多台4503都有这问题4503的机箱,4013+ts引擎.

问题：设备时没有加载IOS而是直接进入rommon模式，开始发现寄存器的值是0x2000就改成了0x2102，反复出现重启多次，还是进入了rommon模式，只有敲入boot的命令才能正常。

rommon 1 >

解决方法1：

在ios 的配置里指定启动ios镜像文件的位置，但是一定要注意格式；

     boot system flash bootflash:cat4000-is-mz.121-11b.EW  

“ bootflash：”在系统里没有提示容易忽视，如果不加系统还是不能正常启动。

解决方法2：按照如下步骤来操作:
