Precision 7520 Every Boot: Error sending End Of Post message to ME: HECI disabled, proceeding with boot!

I bought a Precision 7520 refurbished a few months back and I can't seem to figure out how to eliminate this error on boot.  I have verified that this machine was originally configured with it's Management Engine disabled (It has the yellow sticker inside that says 3 ME Disabled) which is fine with me.  I wouldn't use it so it's just a potential vulnerability so I'm happy to not have it.  As far as I know this means there is no management engine to send an End Of Post message to so it would make sense why it would have trouble doing it, but how do I make it stop trying?  Is there a BIOS option somewhere to stop this message from coming up?
