xmodem to 2509

Is it possible to xmodem an IOS to a 2509? When I set the configuration register to 0x0 it boots to a prompt of ">". When I enter ? I don't see an xmodem option.

A 2500 uses RxBoot to change the IOS. Google for the instructions. They should be on the Cisco site.

I don't think you can use xmodem in a 2500s rommon. You can use o/r to set the configuration register. ex: If you need to use xmodem you could try setting the configuration register to 0x2101 ("o/r 0x2101"), then using "copy xmodem flash".

EDIT: I didn't see tiersten's post, he probably knows more about this stuff that I do.

A 2500 runs IOS directly out of flash and the built in ROMMON is very basic. It isn't like the newer routers which copy IOS into RAM and then run it. This means you can't actually change the copy of IOS you've got in flash whilst IOS is running.

The solution is running RxBoot which is a stripped down version of IOS that is kept in ROM. You boot that, erase the flash and then upload your new version of IOS. You can use T FTP in RxBoot.

Thanks fellas. I appreciate the help. I will give it a try later on. For now I have to pay attention to the other love in my life besides Cisco....cutting wood for the woodstove

Ok...I have it all setup. I gave the AUI ethernet port an IP address in the same range as the T F T P server and assigned a gateway. I can ping both directions but I can't copy the new IOS to flash. Here is the output:

Turn off the firewall on the machine running the T FTP server.

boostinbadger

I don't use a firewall. In fact, I use nLite to completely remove it

tiersten

You sure your T FTP server is working?

boostinbadger

I figured it out. It was a problem with the T F T P server. For some reason I have to stop and restart the T F T P server once in a while and it works again.

Now I am running into a problem not being able to erase the flash. Here is the output:

Run the following:

show flash chips
show flash err
show version

You've probably got an old boot ROM and a stick of AMD flash.

Here is the output of those commands:

This is what I get after a power cycle. Is it because the flash is empty or is it another problem?

It must be bad flash. If I take it out and leave the original 8mb stick in, it works fine.

I guess I will just use c2500-i-l.121-27a. It's only an AS anyway.

tiersten

It is only detecting the first bank of flash. It is either bad flash or your boot ROM is so old that it doesn't like 16MB. I know some of the really old ones would need an upgrade to handle 16MB and AMD flash chips.

It should look like this:

How do you go about upgrading the boot rom? Doesn't that involve actually installing a newer chip?

Yeah. You'd have to remove the old boot ROM from the socket and plug in a new one. You used to be able to request it from Cisco if you had a SMARTnet on the router but now you'll have to buy it off somebody.

As you said, you're going to use it as a console server anyway so probably not worth the money and time.

boostinbadger

Good call. Thanks for all of your help on this tiersten. Where abouts in the UK are you? I've visited Swindon a couple times.
