how can I dl JJOS without the OG CF card?

yeah so long story short my dude sold me his MPC with some secondary CF card with like Just Blaze sounds on it or some shit, and has of course lost the original one with the Akai standard OS on it. But I need the JJOS because the Akai standard sucks dick. So what do I do?

You dont need the original card to DL the JJos.

Is it possible from a HDD?
