Hi - I noticed something that maybe someone can explain to me if this is unusual or normal. Notice that the IOS version is not the same as the BOOTLDR version even though the router has the boot system command.
Cisco IOS Software, 7200 Software (C7200P-ADVSECURITYK9-M), Version 12.4(15)T3, RELEASE SOFTWARE (fc1)

ROM: System Bootstrap, Version 12.4(4r)XD5, RELEASE SOFTWARE (fc1)
BOOTLDR: Cisco IOS Software, 7200 Software (C7200P-KBOOT-M), Version 12.4(11)T3, RELEASE SOFTWARE (fc4)
boot system flash disk2:c7200p-advsecurityk9-mz.124-15.T3.bin
so which IOS version in this router actually running?
Thank you very much for your help!!!
On a 7200, "dir bootflash:" should show you your boot flash contents. You should see the file for your C7200P-KBOOT-M, Version 12.4(11)T3. (Believe this is where crashfiles are normally stored on this device too.)
Ideally, when you upgrade the main IOS you can upgrade the boot IOS to the same version, although as Jon notes, there's often little need to do so.
If you did want to upgrade the boot IOS, you erase or format the bootflash as you would normal flash (NB: format might not be supported on that flash type), and just copy a new boot IOS to that flash.
Which software is currently running? Your main IOS, although I believe it initially booted using the bootflash IOS which it turn loaded the main IOS.
The "boot system ... " command is used to tell the router which IOS to boot if you have multiple IOS images. It is not used to tell the router which bootldr to use.
If you want to change the bootldr you need to replace your existing one but if everything is working fine i wouldn't recommend it.
