Messages during booting

Messages when booting
While the TCU boots, a progress indicator is displayed with messages showing the current
status after the BIOS has been loaded and before the operating system is started. While the IP
address is being determined via DHCP and the TFTP is being downloaded (boot image), a
progress bar indicates that booting of the TCU is not yet complete, or that a fault has occurred.
The figure below shows the structure of these messages:
You can see the current boot phase below the progress bar. If a fault occurs, you can call further
information by touching the "F1" field.
