Thanks to Dr. Tom Blinn for responding. Tom looked at the ace driver
source code (he works for DEC) and noted that the error message I was
seeing basically meant the driver was not seeing the hardware. He
suggested that my isacfg settings may be wrong. He suggested doing
an ">>> isacfg -init" to set the isacfg back to the factory defaults, and
then editing the isacfg to add back in any custom settings I had. I
did that, did an ">>> init" and after booting the driver seemed to load
fine. Note however that the isacfg settings did not change (I wrote
them down before going to factory defaults). The difference was the
">>> init". I don't think I did this before when I changed my isacfg.
That must have been the difference.
Thanks,
Mike
