Pat Barron <pat(a)transarc.com> wrote: Correct, except that since Ultrix is binary-only chainware, you would have to disassemble and patch some of its kernel .o files in order to force is to recognize SCSI disks. It uses the CPU code (a byte-sized number constructed from the SID and SID extension longwords) to index into a table of pointers to routines for different CPUs, and the routines that get called when the CPU is KA410 (VS/MV 2000) don't bother to probe for SCSI disks. This means that any SCSI disks you may have attached will be silently ignored, even though the drivers are present and they would work if they weren't artificially blocked. Adding BabyVAX support (with MFM, SCSI, LANCE, and everything) to 4.3BSD-Quasijarus is in my plans. For more information, subscribe to the Quasijarus mailing list. If you want to have something running now, you can either run Ultrix and learn to live in binary-only chains, or you can construct a system consisting of the Ultrix kernel and the 4.3BSD-Quasijarus userland. There is enough syscall compatibility between 4.3BSD and Ultrix to make this possible.

There is a reasonable alternative. NetBSD runs on the 2000, many 3100 models, and even the 4000/60, which Ultrix never ran on. It will also run 4.3BSD binaries -- in fact, in my experience, more of them than Ultrix will. I ran Ultrix on a 3100 on my desk when I worked at DEC, and it was even odds whether binaries I'd built on 4.3 would work correctly -- remember, Ultrix branched from 4.2, not 4.3. SCSI on the 2000 is supposed to work pretty well, SCSI on some 3100 models less so; the LANCE ethernet on the older boxes and the SGEC on the 4000/60 work; a few models support graphical console on a QDSS or equivalent. For the boxes where you're stuck with small RD series disks, shared libraries may help a bit. Hope this helps.
