The CreationParameters recorded in the firmware's shared memory by the process that started the firmware. Attachers (Get(), or Create() when the firmware is already running) adopt the creator's parameters rather than overwrite them, so every process sees how the firmware was actually started. If nothing was recorded (the firmware was started by hand), the parameters this object was created with are returned.
Note
ControllerIndex is the exception: it always reports this process's controller index (the same value as NumberGet()), since different processes may use different indices for the same firmware.
