Hard disk partitions

Division of the hard disk
The hard disk is divided into a primary partition C and an extended partition containing the
three logical drives D, E and F. Partitions C and D work with FAT16 file access and drives E
and F with NTFS file access.
The hard-disk partitioning corresponds to the grouping that is required for installing the HMI
system software onto the PCU under Windows XP. Windows XP can be used with PCU 50
V2 (566 MHz or 1.2 GHz, 10 GB or 40 GB hard disk). For reasons of data security, the HMI
system software and the Windows XP system software are distributed on the different hard
disk partitions.
Depending on the order details, the HMI system software may be pre-loaded on delivery. It is
installed subsequently by the customer the first time the system is booted up.
The following figure shows how the hard disk of the PCU is used:

procedure.
Reserved for the Windows XP software.
The Windows XP software is available on the recovery media CD via
network, in order to later install drivers or updates as needed.
For installing user programs.
Applications such as HMI system software (incl. data storage and
temporary data), STEP7, OEM applications for HMI, or customer-
specific applications should only be installed here.
