Booting from the second hard disk drive
In order to allow booting from the second hard disk drive, you need to configure it as the
primary boot device (Boot Option #1). Make the following settings in your BIOS setup:
1. Select the "Boot" tab.
2. In the "Boot Option Properties" area, select the first entry from the list: "Boot Option #1" and
press the Return key.
3. Select the corresponding drive (slave drive) in the "Boot Option #1" window, e.g.
STxxxxxxxxx, and press the Return key.
The second hard disk drive (slave drive) becomes the primary boot device.
Note
The drive letters for the partitions on both drives are assigned by the operating system in
use. You can change these in the Control Panel as required.

RAID system management functions
The following options are available for setting up a RAID system:
• Hardware RAID of a RAID controller
Note
A hard disk can be synchronized at operating system level if a fault is detected. It may take a
very long time to synchronize a new hard disk in the background, depending on the size of
the hard disk and on the system load. It may take several hours or even days in the case of
extremely high hard disk load. Guide value for duration: < 3 h with 90% HDD system load and
RAID5 with HDD 1 TB.
The safe system states RAID Level, for example, 1 are only reached once synchronization has
been successfully completed. In addition, system performance may be limited in the case of a
manually started maintenance operation until completion of the maintenance phase.
Note
Password protection for RAID setup
To prevent access to the optional ROM, follow these steps:
• Set the supervisor password in the BIOS setup.
• Disable keyboard operation during the BIOS self test (POST) in the BIOS setup.
You can obtain more detailed information about the BIOS setup from the manufacturer in the
manual on the motherboard (Page 108).
