MTUSUPPORT is on vacation, but even he probably can't answer this one.
I am assuming you have a Kristal DSP card which is a PCI-slot card, not the older DSP56K ISA-slot card.
The Kristal card uses the Motorola 56301 DSP chip with its PCI-bus interface. This chip had some problems with some PCI-bus implementations. We always had to pick the motherboard we sold in workstations, and recommended. I don't know what is now available.
It sounds like you are quite technically capable. However, we no longer have any technical staff that can answer your question.
It may be easier to try a different motherboard. I don't know any way you could make the Krystal card work in a motherboard when it was incompatible. I believe it is at the hardware level, buss timing probably, that prevents operation. This timing is integral to the entire motherboards' performance. The Motorola 56301 was first shipped in 1997 to us (one of the first customers to recieve product), and we discontinued production before 2000. This was due to Motorola discontinuing the 56401 Digital Audio interface chip that was integral to the Krystal board. It was the clock that drove all audio timing circuits.
Maybe someone else can throw out a better suggestion here.
