不用格FLASH吧,启动时不加载Startup-config就行了;检查一下bootdisk

配置都存在NVRAM里面,把MSFC3上的钮扣电池拆下来,过30秒装回去,配置全部清空,清空后记得自己修改正确的寄存器值。
如果不想扣电池也行,在引擎自检切换到RP的时候,CTRL + BREAK中断,进入RP的rommon模式,然后输入confreg 0x2142回车,然后出入reset回车,恭喜你,你肯定成功了!

一定要进入rp的romon模式再修改寄存器值,这是才能清空配置。刚启动是是sp,要等一会rp启动时再进rommon

rommon 1 > confreg 0x2042 (有些资料说0x2142,但0x2042实测成功)
You must reset or power cycle for new config to take effect
