And to respond to Noels remark about this being around for a long time without reports - since this is in FPSIM, and I believe the notes for 2.11BSD even says that this is an untested piece of code, which are not even know if it works or not, it's not something that have been used for ages. I'm in a way surprised it even worked at all. I think I've seen somewhere that it was last tested around 2.9BSD, and have not been officially tested since. > The essential hint was Johnny's observation that on his system he gets > an "Illegal instruction - core dumped" and no kernel panic. Well, had I had FPP simulated, I would maybe not have gotten a kernel panic anyway. It would all depend on where the address ended up. With my current build, the kernel would have been able to read the address, since it pointed into the boot diagnostics rom. So it's a dicey error at best. But the tcsh error was very good that you also figured out. And I guess it means we now have a known working FPSIM. :-) Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.
