ATTENTION
8.3 Priority of the start-up devices
“Start-up devices” refer to the CFast card or to the USB flash disk or to other mass memories where the oper-
ating system is stored (for example Windows) which start up the computer.
As a standard factory setup, the research of the operating system first occurs in the CFast, then in the USB
flash disk whenever present. The first device of them that contains the start-up informations needed by an op-
erating system for starting is used.
Therefore, if you want to start up the computer according to a different sequence, it is necessary to modify the
setting in the CMOS Setup or remove any other start-up devices (for example, by removing the CFast).
According to the functioning mode of the BIOS in the POSYC, the start-up sequence automatically follows the
variations of the quantity or serial numbers of the start-up devices; in fact the new devices, that were not pres-
ent at the previous start-up, are listed as the last ones in the start-up sequence.
From this it follows that, for example, by replacing the CFast that contained the operating system, it is not used
for startup when it is turned on; it is therefore necessary to correct the setting in CMOS Setup (see paragraph
10.3) or temporarily disconnect the other start devices.
If necessary, then, via the USB keyboard connected to the POSYC, enter CMOS Setup by accessing it using
the STECH password (power the computer and as soon as the Smitec logo appears, press the Del/Delete key
on the keyboard).
Be careful not to modify any other parameter, otherwise the device will not work.
8.4 Power ON
When the POSYC 3303 is powered, for about 4 seconds the device will switch on and then switch off for the
same period of time. Subsequently, the device will restart, with the peculiarity that the cooling fan will initially
run slowly and then increase its speed until it is working.
Pour éviter toute panne d'ordinateur et / ou toute perte de données sur la carte CFast, son
remplacement doit être effectué exclusivement à POSYC off.
