I upgraded a 2811 router to the latest version and apparently everything went smooth. I reloaded and did a sh ver the IOS show the correct version, but the boot strap shows the old IOS. How can I change the boot strap to show the new IOS
You seldom, if ever, upgrade the bootstrap on routers. It is not usually upgraded and therefore it is completely normal for the bootstrap - or better said, the ROMMON - to show a different version than the full IOS. The ROMMONs are not released in identical versions to IOSes, and in fact, they are released only to correct some serious errors or limitations of previous versions.
Don't worry about it. It is normal and expected.
