Bootstrap-IOS compatibiliy

Please advise how to determine valid match of bootstrap version and IOS version. I need to know what ver of bootstrap I have to have on the 25xx router to make it work with IOS 12.1

Thanks

Re: Bootstrap-IOS compatibiliy

You don't need to upgrade the bootstrap/bootroms on a 2500.

Usually, it's recommanded to sync the bootimage with the main image (ie if you have 12.1(5) as the main image you should also use a 12.1(5) boot image). This is not the case for 25xx where bootimages are on a bootrom and are not meant to be synced with the main ios running on the router.
