Hello all,
I've been getting increasingly sick of Ultrix lately and I'm determined
to get NetBSD running on my 5000/125s (albeit with PMAG-CA cards). I'd
like to know if the information presented in these structures is already
known; and just how much we do know about these cards, so I don't
waste effort. As I understand it the DAC and STIC are currently understood
(partially, anyway, to the point of where they can be initialised). Is
this the case?

Regards,
Andy.

Here we go:

   unsigned minval;
   unsigned maxval;
