2 Boostrap?

Hello everybody... Recently I bought a Cisco 3745 and found 2 Boostrap at the router startup, here is the log :

System Bootstrap, Version 12.2(8r)T2, RELEASE SOFTWARE (fc1)

I know that this Boostrap version (12.4(13r)T5) is the lattest for this router. Should the 2 Bootstrap appear in the startup? Or maybe there is a little trick left for the correct upgrade? Thanks in advance guys.

Hey guys, nobody?

tiersten

Its normal. Somebody has upgraded ROMMON on that router. The factory supplied copy of ROMMON is never actually deleted or overwritten but just chain loads the upgrade ROMMON which then loads IOS.

Thanks a lot tiersten, now I can figure out that the factory default for the 3700 series, and the 2691, is 2 ROMMON places to store the bootstrap, one is ROM (which has the factory ROMMON) and the other is EEPROM (which allow the upgrade), so even after the ROMMON Upgrade we do still have the old ROMMON that can't be overwritten... But if that's the case, why Cisco states, and everybody else, that if the upgrade fails or you encountered a blackout then your router will enter an unrecoverable state? Isn't the old ROMMON is still there and can take over in case of a failed upgrade or even a damaged ROMMON image?

I thought it gets overwritten, hence the unrecoverable state, but if it's not then why do we need to ever worry?! It's kind of those new motherboards that ships with 2 BIOS, one is in use and the other is only for Backup purpose, 1 BIOS was a pain in the neck before...

They're both in flash. The software just doesn't let you overwrite the factory copy of ROMMON.

Because you may end up corrupting something still.
