There isn't some convenient register that you can read for > this. 8( Back in the days when I ran 4.[23]BSD on my VAX 11/750, the autoconfig code planted trap catchers in all the likely interrupts vectors. All you had to do was poke at the device being probed enough to cause an interrupt, any interrupt. I don't seem to recall configuring interrupt vectors in my kernel config, and the good thing about UNIBUS peripherals is that you weren't likely to run out of interrupts. Or am I just dreaming this? louie
