questions for DO's in ACGME program

I am a DO doing an ACGME residency in NYC. I have a few questions - I take the ABIM board since I did the ACGME residency, right? or is it AOBIM. Am I certified by ACGME or AOA. - Given that we did an ACGME residency in NY, I don't have to get the first year approved by AOA. - I go ahead to pursue a fellowship ( ex- AOA) do rules change regarding boards ( ie- I have to also take AOA IM boards). The confusion also arises with the merger. Thanks!
