Depending on the order, the operating software can already be installed when the unit is
shipped. It is installed subsequently by the customer the first time the system is booted up.
For reasons of data security, the operating software and the Windows XP system software
are distributed over the different hard disk partitions.
Content of the partitions
The individual partitions are intended for the following data or already contain this data:
EMERGENCY (C:)
TMP (D:)
SYSTEM (E:)
USER (F:)
NOTICE
All of the applications must be exclusively installed on USER (F:) even if these applications
have a different drive set as the default drive in their installation path.
The partition names EMERGENCY, TMP, SYSTEM, USER must not be changed;
otherwise the "ServiceCenter" will no longer function.
