question on upgrading IOS on cisco router

Hi all,

I want to upgrade my cisco 2620 router's IOS from 12.0(1) to 12.3(13)
I have never done such task, but I have been told that it is not difficult!

I have the following tools:

1. solar wind TFTP program (install on laptop)
2. IOS version 12.3(13)

3. local network(with private ip addressing scheme) connected to the net via router (router has 4 ethernet connection for my private network and my cisco 2620 router will be connected into one of the ethernet connection)

4. ethernet patch cable (for connecting my cisco router 2620 to my local net)

what else do i need????

if you know any link with step by step instruction please direct me to the right link.

Make sure you back up the old IOS to the TFTP server first.

Acouple of things to note:

1. Verify that you have enough ram and flash installed to run the IOS image you have downloaded.
2. Verify the new IOS you have will support all of the features you will need to use with the router.

P.S. If you want to challenge yourself then do this from rommon.

yeah I agree with eric0, try loading it from hyper terminal in rommon. that is a good challenge.

The only thing that's gonna challenge is your patience. If you can tftp it, I would avoid xmodem.
