Ok, makes sense. I suppose I have to find an original
system master to
make my own sysgen. Though the boot disk I'm using now suits me fine for
my current purposes.
Problem is that it is wrong. The monitor, at boot time, will fill
in its tables for devices it finds (up to 40 devices). Except for
the system device, which is loaded so that it can't be unloaded,
these handlers are considered 'installed' if the I/O page addresses
indicated as required in the handler exist. This does not mean
that the handlers have been loaded. Handlers are not automatically
loaded by RT-11. They can, however, be loaded using the startup
command file. They can also be .FETCHed by properly written
programs.
