I am currently trying to bring up 4.1 on a VAX 11/780. Just for completeness, the configuration is an RP07, a dz, a lineprinter, and 2 M of memory. The first problem is that the memory controller is one of DEC's new controllers that use 1 M boards. When I boot the system, I get the message : nexus type 6c unsupported (at tr 1) The system does go ahead and boot, however. What do I need to do to support this type of controller, anything special? Also, in a possibly related case, I can not get the system to probe the dz and the lp. After many debug messages, I have found that the call to "badaddr" with the addresses for each of the devices fails. The lower part of the address appears correct, but the upper half is computed in a mysterious way. Is this top half being mis-computed because of the mcr? Or is there simply a problem with the uba itself? I will appreciate any help, leads, or rumors. So far nothing seems to have worked (and believe me, I have tried some pretty out-landish things at this point). P.S. Anyone got a straight 4.1 driver for a dmf32 board? I haven't even tried putting this in yet, but will have to eventually. -- eric ...!seismo!umcp-cs!aplvax!eric
