在rommon 1〉状态下有两种升级IOS方法。
（一）、通过Xmodem命令（注：Xmodem与实际的modem没有任何联系 只是一个传输协议 数据是通过终端的串口和路由器的Console口灌进去的）升级IOS，具体步骤如下：
1、用Cisco原配的线缆连接路由器的console口与PC机的COM1，使用PC机的超级终端软件访问路由器，这时不需要对PC和路由器配置任何地址。
2、在这个模式下，输入Xmodem命令，即：
rommon 2 〉 xmodem -c c2600-i-mz.122-11.bin
（-c是带校验，c2600-i-mz.122-11.bin为存放在PC机上的IOS映像文件）
WARNING: All existing data in bootflash will be lost!
Invoke this application only for disaster recovery.
Do you wish to continue? y/n [n]: y
Ready to receive file c2600-i-mz.122-11.bin ...此时在超级终端的传送栏目=〉 选择发送文件选项 =〉 再选择Xmodem 并指明IOS映像文件所在的路径，按发送即开始上传IOS,等待时间很长，视IOS的大小和传输速度。）

采用这种方法时，由于使用console口来传送，速率为9600bps，需要时间较长。因此可修改console口速率利用xmodem命令实现快速升级IOS。具体方法如下：
rommon 1 〉 confreg 回车
