3945E IOS Upgrade bootstrap question

Hello,

I upgraded from c3900e-universalk9-mz.SPA.151-4.M1.bin to c3900e-universalk9-mz.SPA.152-2.T.bin, but the bootstrap is showing: Version 15.1(1r)T2.

Is this OK?

If both images remain on flash the system will boot to the one located 'first' on the filesystem. You can use the 'boot system flash:c3900e-universalk9-mz.SPA.152-2.T.bin' config command to force a boot to the other load.

Oh, also just to be sure: the bootstrap is separate from the actual IOS image running. A 'show version' will tell you that. Bootstrap is also known as ROMMON and is just there to recover the router.
