Thanks for the info. It sounds like everyone can at least get their cards to function. As soon as I invoke any of the supplied utilities, I get a RAMLIB ERROR #800000004. I get no indication that the Delfina exits in my system, it's mounted on clock port 0 of an X-surf (which does work well). I may try shooting an E-mail to IC. AmigaU, you say the specs are impressive, I agree. In fact, for the last year, the manufacturer's web site went on about "..there's nothing we can't improve..". If I had known the bugs weren't resolved, I would not have invested. Next time, I'll post my questions before buying.
