Here's something to check: Your boards should be set at different 
addresses, or you will get the VAX equivalent of an IRQ conflict. And 
then you will need a custom kernel to recognize the second board at an 
alternate address.

I'd suggest removing one of the dhv11 boards and retrying, to see if you 
get any response. Both boards could be mapped to the same address, and 
neither would probably work then.
