There seems to be two different MDC2 versions of this module. Can anyone tell me what the difference is between the two?. I know there is also the older MDC BluOS-2i version, but i'm not talking about that one, i've actually seen photos of these two cards with these two designations on the back..one with, and one without a "D", yet both are MDC2 modules. Is there one available without Dirac maybe?
