I've very strange problem on 3725 router. I've updated it from 12.3(9) IPBASE to 12.4 IPBASE+K9 IOS version.
First of all, I've tried:
- 2 different Cisco 3725;
- 2 different IOS: 12.4(10b) and 12.4(12)
- Updated bootstrap to Version 12.4(13r)T5
- confreg is 0x2102
The problem is:
1. I copy new IOS to flash;
2. I delete old IOS from flash;
3. I reboot router;
4. Router goes to ROMMON;
5. I enter "boot flash:IOSNAME" and router boot to normal state;
WHY? Something wrong with IOS on cisco site? How to add or calculate magic number?

Since you are able to boot the router using the new IOS image there's nothing wrong with the image. It appears the config register setting may be causing this. Can you verify whether the config register is set to 0x2102. Moreover, if you have a 'boot system' command in the configuration that's pointing to the old IOS image then remove it and make it to the point to the new IOS image or just don't leave any boot system commands in the config.

I've opened TAC request about that. So, the answer is: IOS file should be the FIRST on flash. It's not so, it's clear from "dir flash:" in ROMMON.

Hi,
I Agree with what Sundar says.
As per your post it seems you have uploaded the ios but its not able to take the boot file which you have uploaded, for this you will have togice command
boot system flash:filename.
