---------- Is there someone on the net using minix on vax as a teaching tool? I cannot get the pc_simulator that comes with the minix distribution on vax as described in the minix book. We have a vax8530. I have over 30 students and only a few pc's being shared among a large number of classes. It would be a tremendous help to allow the students doing some of their work on the vax. If someone has experience running minix on vax, please send me e-mail: unccvax!billchu@mcnc.org Thanks very much. -- Bill

Please, anyone who responds to Bill's request, send me your
response, too? I'll have a similar problem in just a few weeks.
Thanks,

I must admit, I haven't used the simulator since 1.0, so I am not entirely surprised that there are problems now. My intuition says that the 8088 interpreter is pretty solid, but that all the new I/O stuff added since 1.0 (hard disk, AT ram disk, EGA, etc) is the source of the trouble. Fortunately, the simulator is 100% in C, and has lots of debugging capabilities. Start a run up and print out, for example, every control transfer instruction (jump, call, trap, etc) to see what it is doing and how it got there. I would also put a print statement in the 8088 interpreter code for the IN and OUT instructions, to see what is going on. Andy Tanenbaum (ast@cs.vu.nl) P.S. If you finally get it debugged, I am interested in the bug fixes too.
