Configuration: Vax 780 running 4.2 bsd one unibus one uda50/ra81 one tu80 and controller one dz I am trying to install an Emulex dmf board, but am having troubles. When the board is in the unibus, the system will boot, but it hangs after seeing the second dmf. (The emulex is configured to look like two dmf's). I tried booting genvmunix and the system did come up after only looking for one dmf, but it tends to crash if you try to access the ra81. Simple things like mount -a or ps do not work. We did remove the mpr jumper because the dmf is a dma device. The vectors for the dmf's are 734 and 674. The vector for the uda is 774. I have had some suggestions that the vectors for the uda and the dmf should not be so close together, but that sounds a little like black magic to me. Does anyone have a similar configuration that is running. Or barring that, does anyone have a suggestion? linus!sid
