I gotta Problem.

[a.ford]

Problem:

I just purchased a 4500 router (no problem there). However, somebody put 2600 IOS in the flash.

Another Problem:

The router has a password set so I can't even boot from ROM, which has the correct IOS (4500). In other words I can't go into enable mode.

One problem stops the other.

Any suggestions "ANYBODY"

Now really sorry, I think I've been seriously wrong all along. The above procedures work well on other routers platform like 2600 and 3600, but not on the 4500. Check out the following links for info on what to do to your box

Here in lies the problem, I've been here before. Now all would have to do is "en" and get the image. The problem is I don't have the password for this router. I can't do a password recovery due to the flash issue.

You dont have any other choice other than the PCMCIA flash card. If you have similar router with PCMCIA flash card, load the proper image on that flash card, then move that PCMCIA card to your router. Then boot.

Hi there.

The prompt "sa-amb(boot)>" to me sounds like you're in what Cisco called RXBoot. This is a level 1/2 way between ROMMON and full featured IOS. See if you can get into ROMMON (cold boot router and press the Break key on your keyboard as soon as you see some message on the screen. I remebred that if you're using standard MS Hyper Terminal then Break won't work). ROMMON mode is the one where you can specify the values of config register. Specify a config register value of 0x2141 and then reboot your router. The value "4" specify "ignore config in NVRAM" and the last value "1" specify boot into RXBoot. You'll end up with the prompt "sa-amb(boot)>" like you did before and from here you should be able to get into priviledge mode without having to specify a password (default value). Post a reply once you have this working and I'll show you how to upload new IOS without XModem.

Nothing to be sorry about, I'm thankful for any and all help.

is it possible to setup a small tftp server and use tftpdnld from rommon ?

or isnt that commend supported in your bootstrap version ?

You could grab a spare laptop and setup the server on that.

[deilert]

Ok

1. tftp dpwnload will not work on a 4500 only on 2600's

2. If you were getting a [assword prompt earlier there must be a good image on it .

I saw eralier in the post you got the box to boot to router(boot)., this is good , get to this again dh a sh flash and post the sh flash .

Here in lies the problem. Someone load 2600 IOS onto this 4500 (I don't know why)

RE (fc1)

any recommendations?

[a.ford]

the system doesn't reconize the tftp portion of 'tftpdnld'. The system can't seem to find xmodem either.

[thisisshanky]

Do the following:

1. break into rommon (press Break key during first 60 seconds

2. rommon1>confreg 0x2142

3. after setting above value to config register, it will prompt you to reset the router. Once its reset, the router will now boot into Rxboot mode (Router(boot)>) after ignoring your configuration files. Now it wont ask for any password.

4. configure an ip address for the ethernet interface and connect it to tftp server, and download new ios into flash using "copy tftp flash" command

Hope that helps!

See the show flash and show ver commands.

Change the config setting to 0x2141 (confreg 0x2141). This should take you to Rxboot mode.
