    Hopefully someone just changed the configuration register to speed up the console port from the default 9600. Try the various speeds in your terminal software.

    From the output it would seem the flash may not be seated in correctly or possibly blank/corrupt. If it was me I would check it is in correctly physically. Then if needed format flash and restore the IOS via xmodem or TFTP.

    Looks like your flash is missing (or loose) -- time to open the chassis and see what you have. Someone could have "downgraded" the router by "borrowing" the flash from Socket 0.

    Reinstalling an IOS to flash from a PCMCIA memory card (and any good 3660 IOS image to boot from) is the easiest way.

    I dont have with me a PCMCIA memory card. this router had been in the stock room for quite sometime. the only way i could install an IOS to this router is via tftp.

    but im getting this error....

    what you posted looks like the router is searching for a TFTP server in which to boot from...that TFTP server should have the IOS image file stored in it's TFTP folder.

    without any flash in the router, there's no place to store the IOS ... so you need flash memory and the IOS or flash memory and a copy of the IOS that's stored in the TFTP server.

    If you have access to the TFTP server just make a copy of the 3660 IOS, go get some flash for that model, install the IOS to flash, then change the registers and how the router boots to the IOS...

    Did you try the dir command in ROMMON to see if there is any flash memory -- and if so, what's on it?

    Can the 192.168.1.1 device ping (or tftp) to the 169.254.252.226 TFTP server?

    What kind of PC is the TFTP server? UNIX? Linux? Windows? What TFTP server? Is security set to allow anonymous download?

    Have you tried a tftp client from a PC on the 192.168.1.0 network to see what files it can see on the TFTP server (assuming it can reach the TFTP server).

    What terminal emulation software are you using and did you quickly start the XModem upload from your software?

    And if you're going for XModem, did you change the port speed via config register (and your PC serial port terminal software config) to use something like 115k rather than a paltry 9600?

    It looks like you tried to upload a couple of different IOS images, but you always show this first.....

    How about a dir command so we can see how much flash you have and what's on it.

    Right now you seem to have a corrupt image that hasn't been deleted when the flash was "erased" at least twice now -- unless you uploaded that corrupt image twice between the terminal output you did post....


    So you're not getting the "FLASH socket 0 is empty" error any more?

    Upgrading System Memory in Cisco 3600 Series Routers [Cisco 3600 Series Multiservice Platforms] - Cisco Systems
    Each Cisco Flash memory SIMM socket corresponds to one bank of memory. Fill starting with bank 0, and empty starting with bank 1. Bank 0 must always be filled first and emptied last.
    If someone pulled the SIMM from Flash slot 0 you'll probably need to move the SIMM from slot 1 and put it in slot 0 (or upgrade the Flash).

    Did it ever do a successful XModem transfer?

    How much flash do you have installed? Where'd you get it? Is it known good working flash memory? What do you get when you do a dir flash from ROMMON with this flash mamory?

    Do you still have this error?

    If you remove any modules and power up, does it boot to ROMMON without any errors (other than maybe not finding an IOS image)?
