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
