Good luck. I never got this to work. With the early connect32 cards it
appeared that interrupts may just not work full stop. The RISC OS driver
did not actually use them. Andreas Gandor (andi@knipp.de) provided me with
some information which did include the register for enabling interrupts
but I could never get any to be generated and further conversations raised
the possibility that the interrupt logic in the PAL on the connect32 has
been disabled/removed as it was not being used on the card I had.

The coscreg.h lists an offset and bit for termination.
I think I may have some DMA addresses scribbled down somewhere though
finding them may be tricky ;-)

Andreas was my original contact but that was a number of years ago now.
