@Richneerd First off welcome to the Rockstor community.
Looks like you have already found our now old thread on this card, linking for context:
Again as in that thread I think @bkelly is likely to be the most informed on this matter.
I’m curios where you got this impression as there is very little evidence on the forum of this, that I’ve seen anyway. Personally I think it’s always best to use hardware that is up streamed properly in the kernel driver wise and fully open source / GNU licences, otherwise this sort of thing is much more likely to happen.
Let’s hope there is still support or maybe others more up on hardware can chip in with their success on similarly capable hardware that is properly supported driver wise. It is a far from optimal arrangement if one has to install drivers manually, and for me essentially rights off that hardware.
Hopefully this thread will yield some fresh, more up to date information on this or alternative hardware.
