7.8 Notes on operation
SIMATIC IPC677C
58 Operating Instructions, 05/2010, A5E02722710-01
Booting from the slave hard disk
The system boots by default from the hard disk on SATA port 0. You can also configure the
system to boot from the disk on SATA port 2.
In order to allow booting from the second hard disk, you need to configure it as the primary
boot device. Make the following settings in your BIOS Setup:
Select Boot > Legacy > Hard Disk Drive > <Hard disk name> e.g. P0- ST3500418AS, then
press the "+" key to move it up in the boot order.
NOTICE
The drive letters for the partitions on both drives are assigned by the operating system
used. You can change these in the Control Panel as required.
7.8.3 RAID1 system (optional)
This is a RAID1 system configuration (mirroring with two hard disks). This configuration
enhances system availability as the system is able to continue operation if a hard drive fails,
or if there is a cable problem at a channel.
The two hard disks are configured as follows in the factory state of the device:
RAID1 system
Partition C: System, NTFS, 25 GB
Partition D: Data, NTFS, remaining capacity
Note
You can find information regarding Intel RAID controllers in the RAID documentation on the
included "Documentation and Drivers" CD in the Drivers\RAID\Intel directory.
