So I imagine any device drive with the X at the end is
the better one to
use with the XM monitor? Or is it mandatory to use X device drivers in
the XM monitor?
It is mandatory... the system knows to append an X to any two-character
device name
So this brings up another question: I've noticed
that I don't explicitly
need to LOAD device drivers for the devices I want to use when I boot
RT-11. In particular, I don't need to LOAD DD when I want to use the
TU58 simulator. Are they found and loaded automatically when the OS
boots, or...?
Most utilities and user applications know to .FETCH device drivers they
need in order to do their task. After they are done, the drivers are
.RELEAsed. If they are LOADed before the program is executed, a .FETCH
and .RELEA are no-ops.
If they aren't loaded and aren't .FETCHed, then they simply are not in
memory.
