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. Paul Lansky Music Dept.
