Partitioning of the hard disk
The PCU hard disk is divided into four partitions (three primary partitions and an
extended partition).
S
For reasons of data security, the SINUMERIK 840Di system software, the
Windows NT system software and the Service software are installed in dif-
ferent partitions.
S
A boot manager is provided so that you can boot the system either with Win-
dows NT (SINUMERIK 840Di user interface) or MS DOS (Service menu).

tem is supplied:
