1.4.4 Interrupting program startup
To prevent the user accessing the system level, software applications are usually launched automatically in
full screen mode. Some of the programs are configured with key sequences in order to close the application.
If this is not the case, the system level can only be accessed by changing or re-naming the startup files. An
alternative is to use a key combination at the start that prevents the execution of user programs.
Alongside an abort function integrated in the customer application, a general mechanism is also integrated to
re-access this type of secure access system in a service incident. This is done at the start by entering a
special key combination (prior to booting, not after suspend, see Chapter 1.3.2). The abort key combination
must be pressed immediately once the LED lights up before the boot screen appears on the display.
The startup process is masked by a configurable startup screen. See here Chapter 1.4.1 on page 8.
Once the device has been switched on, the
keyboard controller first checks whether the
keyboard break combination was pressed. If this
is the case, this will be displayed afterwards in
the progress reports.
The key combination 4, 3 and 9 will interrupt the
program startup. The keys must be pressed in
this order immediately after the device has
booted (before the screen becomes bright) and
held down for 3 to 5 seconds (the example on
the right shows a M260SE keyboard)
