password recovery/factory default

chusomechusome Member Posts: 5 ■□□□□□□□□□
I recently bought a cisco 2501 router from ebay for educational purposes. It
came with preconfigured passwords which I didn't have so I used the
instructions at the following link:

However when I get to the point where you should type in startup-config
running-config I get the response unknown command or computer name....

As well the prompt I have is different from the example. It shows:
instead of

the same applies for enable mode:
instead of

and now every time I power the router it gives me the setup program (twice

Very confused here, all help is appreciated.

    The link you provided aboved does not work, but just curious what value did you change the config register to? I think instead of putting it into ignore startup config 0x2142 (defult config is 0x2102)

    here is the method I use

    use hyperterminal --- while router boots --- do Ctrl + Break ( to get into rom monitor)

    to change configuration register to ignore nvram.....

    for 2500, >o/r 0x2142

    to reboot the router.....

    2500, >I

    after this, router boots without looking nvram.....
    #copy start run
    #config t
    (config)#enable secret
    (config)#config-register 0x2102
    #copy run start

    The "router(boot)>" prompt shows that you are in the rxboot mode, i.e. the router is running the limited function IOS stored in ROM. You have probably changed the configuration register to 0x2141. Change it back to 0x2142 and continue with the remaining steps in the procedure.

    ok I understand a little more here now, so the config register is your boot mode. (I work with MS products too often)

    So here's what I've found.
    In 0x2142 mode I get prompted to setup twice and prompt is router(boot)>
    In 0x2141 mode I only get prompted once and prompt is router(boot)>
    In 0x2102 mode I get the following:

    and as you can see I still get the (boot) prompt. This is the way it was oringally setup. Also when ever I run config t I don't get a prompt, instead I get the following output:

    Enter configuration commands, one per line.
    Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z

    thanks for the info but I'm still a little lost here....

    so yes, the real problem seems that i might have gotten screwed here.

    There is no ios on the flash memory, and according to my sources you can only buy the images.

    Does anyone know if there is a place where one can get ios images from?

    Doesn't look like he has any RAM the chasis and I suspect you will see empty slots.

    there is a 1 MB of internal ram
    I also have some simms to upgrade it as well so thats not an issue, just need ios file.

    You can use IOSHunter to get some older images. It is up to you to register the image for use after you have already downloaded it.

    Ok, now I'm seeing a little further into it. (again)

    There is internal working ram, but no flash ram. So now I do have an ios image, but need a pair of 8MB flash simms and a single 16MB dram, which I do have some spares about from old pc's. Will this work or potentially cause damage?
