(2) Select the source disk
Then select the source disk that you wish to use and then click “--->” to
move it to the Selected field. Then click Next to continue.
It is very important to note which disk is the source disk (the one containing all
of the information to be migrated) and which one is the target disk. On a RAID Ready
system, this can be determined by making a note during POST of which port (e.g. Port
0 or Port 1) the single disk is attached to.
You can also use the Intel Application Accelerator RAID Edition utility before
the second disk is installed to verify the Port and serial number of the drive that
contains all the data.expensive (requiring read-in prior to write, in order to
be able to calculate the correct parity information), or
similar to RAID-1 writes. The write efficiency depends
heavily on the amount of memory in the machine, and
the usage pattern of the array. Heavily scattered writes
are bound to be more expensive.
RAID 10 (Mirrored Stripes) –A RAID 1 array of two RAID 0 arrays.
† Strip Sizes:
Select the desired strip size setting. As indicated, the optimal setting is 128KB. Se-
lecting any other option may result in performance degradation. Even though 128KB
is the recommended setting for most users, you should choose the strip size value
which is best suited to your specific RAID usage model. The most typical strip size
settings are:
4KB: For specialized usage models requiring 4KB strips
8KB: For specialized usage models requiring 8KB strips
16KB: Best for sequential transfers
32KB: Good for sequential transfers
64KB: Good general purpose strip size
128KB: Best performance for most desktops and workstations

(3) Select Member Hard Drive(s)
Then select the member disk (the target disk) that you wish to use and then
click “--->” to move it to the Selected field. Then click Next to continue.
Please note that the existing data on the selected hard drive(s) will be deleted
permanently. Do not forget to back up all the important data before continuing. 
						

							5-19Introduction to Intel ICH7R SATA RAID(4) Specify Volume Size
Specify the amount of available array space to be used by the new RAID
volume. You may enter the amount in the space or use the slider to specify. It is
recommended you use 100% of the available space for the optimized usage. For
RAID 0 volume, if you do not specify 100% of the hard drive space, the rest hard
drive space will be worked as RAID 1 volume, which is the new technology called
Intel Matrix RAID. Then click Next to continue.(5) Start Creating RAID Volume from Existing Hard Drive Wizard
Before you continue the procedure of RAID volume creation from existing
hard drive, read the dialogue box below carefully. Please note that once you click
Finish, the existing data on the selected hard drive(s) will be deleted permanently
and this operation cannot be undone. It is critical that you backup all important data
before selecting Finish to start the migration process.

(6) Start Migration
The migration process may take up to two hours to complete depending on
the size of the disks being used and the strip size selected. A dialogue window will
appear stating that the migration process may take considerable time to complete,
meanwhile a popup dialogue at the taskbar will also show the migration status. While
you can still continue using your computer during the migration process, once the
migration process starts, it cannot be stopped. If the migration process gets inter-
rupted and your system is rebooted for any reason, it will pick up the migration
process where it left off. You will be provided with an estimated completion time (the
remaining time will depend on your system) once the migration process starts.
The following screen appears if the migration process is completed
successfully. Then you have to reboot your system to use the full capacity of the
new volume. 
						

							5-21Introduction to Intel ICH7R SATA RAIDDegraded RAID Array
A RAID 1, RAID 5 or RAID 10 volume is reported as degraded when one of its
hard drive members fails or istemporarily disconnected, and data mirroring is lost. As
a result, the system can only utilize theremaining functional hard drive member. To re-
establish data mirroring and restore dataredundancy, refer to the procedure below
that corresponds to the current situation.
Missing Hard Drive Member
1. Make sure the system is powered off.
2. Reconnect the hard drive.
3. Reboot the system to Windows; the rebuild will occur automatically.
Failed Hard Drive Member
1. Make sure the system is powered off.
2. Replace the failed hard drive with a new one that is of equal or greater
capacity.
3. Reboot the system to Intel RAID Option ROM by press  and  keys
simultaneously during the Power-On Self Test (POST).
4. Select the port of the destination disk for rebuilding, and then press ENTER.

5.  Exit Intel RAID Option ROM, and then reboot to Windows system.
6. When prompted to rebuild the RAID volume, click Yes.
7.The Intel(R) Storage Utility will be launched. Right-click the new hard drive and
select Rebuild to this Disk. The Rebuild Wizard will be launched which will
guide youthrough the process of rebuilding to the new hard drive. 
						

							Using 2-, 4-, 6- or 8- Channel
Audio Function
The mainboard is equipped with Realtek ALC850 chip, which provides support
for  8-channel audio output, including 2 Front, 2 Rear, 1 Center and 1
Subwoofer channel. ALC850 allows the board to attach 2, 4, 6 or 8 speakers
for better surround sound effect.  The section will tell you how to install and
use 2-, 4-, 6- or 8-channel audio function on the board. 
						

							6-2MS-7176 ATX MainboardInstalling the Audio Driver
You need to install the driver for Realtek ALC850 codec to function properly before you
can get access to 2-, 4-, 6- or 8- channel audio operations. Follow the procedures
described below to install the drivers for different operating systems.
Installation for Windows 98SE/ME/2000/XP
For Windows®
 2000, you must install Windows®
 2000 Service Pack2 or later
before installing the driver.
The following illustrations are based on Windows®
 XP environment and could
look slightly different if you install the drivers in different operating systems.
1.Insert the companion CD into the CD-ROM drive.  The setup screen will
automatically appear.

After installing the audio driver, you are able to use the 2-, 4-, 6- or 8- channel
audio feature now.  Click the audio icon          from the system tray at the lower-right
corner of the screen to activate the AC97 Audio Configuration. It is also available
