    After the Router rebooted it now hangs after ROMMON version message.
    The hardware info doesn't appear anymore.

    Here's the capture of the terminal console session. I'm using ZOC.

    Last successful boot:

    (Syntax: "VARIABLE_NAME=value" and use "set" to show current variables.)
    "ctrl-c" or "break" stops the transfer before flash erase begins.

    The following variables are REQUIRED to be set for tftpdnld:
    IP_ADDRESS: The IP address for this unit

    The following variables are OPTIONAL:
    TFTP_VERBOSE: Print setting. 0=quiet, 1=progress(default),
    TFTP_RETRY_COUNT: Retry count for ARP and TFTP (default=7)
    TFTP_TIMEOUT: Overall timeout of operation in seconds
    TFTP_CHECKSUM: Perform checksum test on image, 0=no, 1=yes

    Command line options:
    -r: do not write flash, load to DRAM only and launch image

    The image is on the flash. At the rommon prompt, type


    If it boots, make sure the config-register is 0x2102.

    There is a valid image in flash. At least I can say, that before the
    ROMMON update there was a image and a working config and I haven't
    erased the flash.

    I would type "boot" at the rommon prompt, if I could reach that prompt
    by sending a telnet Break to the device.

    I don't know how to alter the conf register, if *no* rommon or IOS exec

    The LED of the Ethernet port went on and off according to the status of
    the ethernet line.

    Console cable and terminal emulator settings triple checked and proved

    The ROMMON version banner appears 1 or 2 seconds after power on and
    thats the end of discussion with this piece of hardware.

    The line (which usually appears later)is the first missing sign.

    Try booting with the old boot rom. If that works then I would say there
    is likely a problem with the new boot rom. Buy another one, they're
    pretty cheap. I'm sure you know this but it's worth mentioning, the
    boot roms are platform dependent.

    If it still doesn't boot then I would try re-installing your
    backed-upped copy of the IOS to flash to make sure it is a clean
    version and not corrupted. It looks like from the output that you are
    getting a rommon prompt.

    After that if it still doesn't boot then it's time to hope you have a
    smartnet contract.

    Good luck.

    it's so silly

    its a silly thing , i had the same problem , everything was ok
    your settings are ok , but the romon is case sensitive so u have to type the setting in capitale letters as follow :

    Rommon 1 "IP_ADDRESS=
    Rommon 2 "IP_SUBNET_MASK=
    Rommon 3 "DEFAULT_GATEWAY=
    Rommon 4 "TFTP_SERVER=
    Rommon 5 "TFTP_FILE=IOS.bin
    Rommon 6 "tftpdnld

    then wait 10 min for the ios to be downloaded from you tftp server.
