Cisco 2600 IOS upgrade went Bad

[mccartha]

How do I revert back to a previous IOS if the upgrade went bad. I can't TFTP because the router doesn't see the E-net ineterface. There must be a way to get the router to boot with a minimal IOS version????

You may need to try an X-modem download:

You can also recovery by using a boot image

There is a way to get it to boot a minimal IOS from ROM. You need to configure the Config register for that.

Good luck,

I used the xmodem command from rommon and changed the speed to 115000 and it worked with no problem. Thanks again!!
