I'm having a bit of trouble getting 2.10 to work on our PDP. Our system is: a PDP 11/44 with 1 meg of memory, two CDC 9762 disk drives a TS11 tape drive two DH11 tty boards The story so far: The generic kernel we got from the distribution tape will boot. (It doesn't recognise our DH11's, tho, so no multi-user.) We've been thru the "Config & Recompile" loop a number of times, trying to get the kernel tailored to our system. Some resulted in a non-bootable system (base segment too large, I think); others resulted in a bootable system that would "panic" for some reason or another. (All from mistakes in our configuration file, I'm sure.) The most successful attempt resulted in a system that would boot and hang: >>> b db >boot boot: 44boot : : xp(0,0)unix 2.10 BSD UNIX #1: Fri Aug 26 01:47:47 PDT 1988 root@:/usr/src/sys/CS44 phys mem = 1048576 avail mem = 204800 user mem = 204800 [hang] Finally, as a sanity-check, we tried to recompile the generic distribution kernel. It compiled okay (with a couple of pointer warnings) and... it hangs, too. To be more specific, here's what happened: [after booting from generic unix] # cd /usr/src/sys/conf # cp GENERIC G44 # ./config G44 [normal stuff] # cd ../G44 # make sunix [lotsa output, 45 minutes elapse] # cp unix /csunix # cp /csunix /unix # sync;sync [reboot, hang] I'm not sure what to try next. I'd appreciate any comments or advice. If more info is needed, let me know. Thanks! --Robert -------------------------------------------------------- Robert Wilhite, sys. admin. ..ncrcae!usceast!wilhite University of South Carolina wilhite@cs.scarolina.edu

Things have really been piling up here. The generic kernel won't recognize your DH11's because it wasn't compiler with DH11 support. The generic kernels are only intended to be used long enough for you to configure and compile your own kernel. The hanging that you describe sounds like you haven't defined the ROOTDEV, PIPEDEV, SWAPDEV, and/or NSWAP correctly. Check those definitions carefully in your configuration file. The generic kernel's values for these are edited in by the script /GENALLSYS. When you just compile the GENERIC kernel and try to run it you get some random set of values for these. Casey
