cisco路由器用xmodem重新快速安裝IOS
先打開超級終端，進入rommon 模式（Ctrl+Break複合鍵），鍵入confreg, 如下：
rommon 1 > confreg 回車
Configuration Summary
enabled are:
load rom after netboot fails
console baud: 9600
boot: image specified by the boot system commands
or default to: cisco2-C2600
do you wish to change the configuration? y/n [n]: y (選擇 yes)
enable "diagnostic mode"? y/n [n]: n (選擇 no)
enable "use net in IP bcast address"? y/n [n]: n (選擇 no)
disable "load rom after netboot fails"? y/n [n]: n (選擇 no)
enable "use all zero broadcast"? y/n [n]: n (選擇 no)
enable "break/abort has effect"? y/n [n]: n (選擇 no)
enable "ignore system config info"? y/n [n]: n (選擇 no)
change console baud rate? y/n [n]: y (選擇 yes)
enter rate: 0 = 9600, 1 = 4800, 2 = 1200, 3 = 2400
4 = 19200, 5 = 38400, 6 = 57600, 7 = 115200 [0]: 7 (選擇 7,用最大的115200速率的xmodem傳輸)
change the boot characteristics? y/n [n]: n (選擇 no)
Configuration Summary

load rom after netboot fails
console baud: 115200
boot: image specified by the boot system commands
or default to: cisco2-C2600
do you wish to change the configuration? y/n [n]: n (選擇 no)
You must reset or power cycle for new config to take effect
rommon 2 > reset 回車
注意：在此時鍵入 reset鍵之前，開始定義串口速度（我的電腦---埠屬性----串口速度調為115200），然後再修改超級終端裡設置速率為115200，記住，一定這麼做！否則出現亂碼！然後關閉這個超級終端，重新建立一個超級終端連接，（期間系統重新開機）啟動後，出現
rommon 1> 提示符
然後,輸入
rommon 1> xmodem -r
Do not start the sending program yet...
Invoke this application only for disaster recovery.
Do you wish to continue? y/n [n]: y (選擇 yes)
Ready to receive file ...
此時，在超級終端的功能表上的“傳送”---“發送檔”----選擇IOS鏡像檔所在地以及選擇使用“xmodem”協議，點擊“發送”即可
然後等待10-20分鐘左右就把3-6M的IOS灌進去了！
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
（修改回電腦串口與超級終端、路由器confreg下的xmodem等9600的傳輸速率）
（videre注：實際用的時候，我發現這個命令總是改不成功，後來發現在line con 0下面有了一個speed 115200，所以即使改register成功，啟動以後router又執行speed 115200,還是不行，所以如果有這個問題，記得把這個語句no掉）
Router>en 進入新IOS的特權模式

此時手工改回電腦串口與超級終端2者傳輸速率為9600
然後敲入
rommon 2 >reset
( 最好關電源)
