In the past, the operating system only had to search for the various devices connected to it on power-up, and once seen, the device would never go away. |
At initial power-up after a machine has been physically reconfigured, the machine adjusts its own machine model. |
These two operating options are to be chosen with the product powered off, they will be taken into account at the next power-up. |
The drive is instantly recognized and ready to go on power-up. |
For initialization on power-up when a tape is present, the method of pulse probing still can be used, but we must be careful not to spin the motors. |
This self-calibration under power-up conditions keeps the performance optimised over the life of the sensor. |
