Thank Admin for your reply.

I have already read that first page (And others) of the link that you have posted and I am no closer to understanding exactly how to install the JAM.

Unless I am reading it wrong, one post actually states that the JAM comes pre-installed on the OpenPLi images.
(Not on mine, it doesn't)

I am reletively new to this and might perhaps benefit from instruction that is a little more detailed.

Thank you for your continued patience and understanding.

Regards, The Soulman.
