Are there any PCI SCSI or DMA IDE cards out there that work with Mediator?

No there aren`t and there probably will never be any, as the Mediator can only do DMA to GFX-Ram on a PCI graphicscard but not into Fast-RAM. Even if there were a driver, the CPU will have to copy over the data from PCI GFX-Ram to Fast-RAM. That would totally eliminate the benefit of a DMA card if not worse.

So the fastATA for the A4000 doesn't do DMA either?

But it's still faster?

Yep, it supports higher PIO modes, so he wastes CPU-cycles more efficiently :lol:
Not really interesting, but it`s there.

The amiga sees the whole Mediator as one zorrocard that happens to sit in one zorroslot.
Or short: Yes, you can.
