Hi all ,
          Here i am in a situation with boot problem in 6509. **When booting
Switch is going to Rommon and there is no veriables configured including
Cofig register & Boot , then if i set those ,and reset it is booting but
after booted there is no configuration in the startup config. if i saved
the running config to startup config only nvram have the startup
configuration . then the switch is working with the configuration i
configured. then if i restart the switch it is booting with out any problem
but if i power off and on again it is giving the same problem again.
The error message i am getting is *Warning: Rommon NVRAM area is corrupted.
Initialize the area to default values

*I have tried to format sup-bootdisk: , bootflash: but no use still i cannot
solve this.
*
here some outputs when booting from off mode (not restart)
