@alexh,
Thanks for the info about IDE-Fix Express and the A4000. I think I read that somewhere a long time ago, but had half forgotten it.
What about the IDE controller on a Buddah Flash Zorro card? Does it compare to the FastATA from Elbox, or the Deneb? I already have a Buddah card, but have never installed or used it, as I just recently acquired it (few months ago) used from someone with a pile of other items.
