2.3 OPERATING SYSTEM (OS)
2.3.1 Bootstrap
The bootstrap is resident.
The bootstrap very briefly takes control of the terminal following each powering up to perform the initialization
and the self-test. Then it automatically runs the OS which in turn starts the applications manager.
Thus the Bootstrap provides the following functionalities:
• Memory and checksum self-test
• Local loading of the OS if absent
• OS authenticity check and start-up.
