Hello Friends, I want to erase all IOS from my flash. I am in ROMMON mode and I can not go to normal Router promt as my IOS is crashed. I am able to download the new IOS from Rommon mode by using tftpdnld or xmodem method. But after the Image download it is given while decompressing checksum error. I want to erase whole flash from rommon mode. Does any body know how to erase the total flash or IOS file from rommon mode. If any body know the command to erase the IOS from flash please please forward it to me...
