I have a device which is capable of interrupting to two different
interrupt vectors.  How do I write a probe routine in the driver
(under Ultrix 2.0 or 4.3) which can set up both vectors and probe 
both addresses, and attach a different interrupt routine to each 
vector?  Alternatively, how could I attach the same interrupt service
routine to each one, and test for interrupt condition there?

The device is the Dec DRQ3B DMA card, by the way.  The fifo will
interrupt to one location and the DMA to another.  Thanks in advance.
