2.11 BSD on an 11/93 with an CMD SCSI Module

It's been a fun journey but I finally have 2.11 BSD (Patchlevel 431) running on my real 11/93. On to the next challenges. Does anyone know which serial device I should configure for in order to get the other serial lines working? Everything I read says they are DL lines and calls the builtin controller a DLV22. There is no such device in the 2.11 config. Any suggestions? Also having trouble with the ethernet. It won't come up. Are there network modules that do not work under 2.11? Any chance that any of this will be fixed if I go ahead and patch it up to 450? I was holding out doing the additional patching until I had everything running but maybe because the 11/93 was the last PDP-11 made maybe there is stuff in there that was added later. I plan to go at it slowly as I had a lot of patches that failed when I was doing this on a simulator but I want to try and get all of them to work on this system. At least I now have a real PDP-11 with a TMSCP tape working so I can try making some real tapes for other things. I have four PDP-11s set up right now with various configurations. I hope to have all of them running something before I am done. bill
