[cctalk] uVAX-II Q-bus help

Hello, I have been trying to set up a uVAX-II to demo at the VCFMW.  I got a BA23 box from Paul Anderson that was originally an LSI-11 box with an H9278-A backplane. The uVAX passes the POST and then comes up with ODT on the serial console. I then have tried to do the configuration of an Emulex QD21 disk controller.  The procedure opens a memory map for DMA to main memory, and then has you deposit to a couple registers.  Then, the controller is supposed to copy a diag/config program to VAX memory via DMA.  This step fails.  I have tried some poking around in the backplane, but so far I do not see a reason why the DMA is not working.  Of course, the QD21 could be bad.  I have tried two KA630-AA boards, same result. Does anybody know why a uVAX-II would not work in an H9278-A backplane?  Are there jumpers to adjust? Thanks, Jon
