I watched Prof. Ferland's video, with difficulty because I'm better at reading than watching a movie. My goal was to define three lines, one towards TK4-, the second towards HMVS (Jay Moseley's system) and the last one for an RJE station.
So I started looking in the documentation and I saw in the sysgen manual that normally in the first phases of the IPL it asked for the time and type of start. Something I had never seen with the VM/370 CE. As I said, I couldn't find a refernce in the online manuals and I had to ask.
I always use SHUTDOWN and every reboot of VM was automatically done without any request.
