Nook Color minor chord at startup

[gmmoon1218]

Hi, I'm really surprised I haven't found anything on this, but even a Google search on teh interwebs doesn't pull up anything - I rooted my 1.1.0 NC using Autonooter 3.0.0 and now when I start the NC it makes a startup sound consisting of a major chord (as you would expect) and then a minor chord. I've searched and not found anything about this behavior. I'm assuming it's a notification feature built in to the Nook, and I further assume it indicates a failure of some sort. Can anyone here enlighten me?
Thanks!
