1.1 Serial ATA (SATA) Hard Disks Installation

This motherboard adopts MCP-RAID southbridge chipset that

supports Serial ATA (SATA) hard disks with RAID functions,

including RAID0, RAID1, and JBOD. You may install SATA hard

disks on this motherboard for internal storage devices. For SATA

installation guide, please refer to SerialATA (SATA) Hard Disks

Installation of “User Manual” in the support CD. This section will

guide you how to create RAID on SATA ports.

1.2 Making a SATA Driver Diskette

If you just want to install Windows 2000 or Windows XP on your

SATA HDDs without RAID functions, there is no need to make a

SATA driver diskette. However, if you want to install Windows

2000 or Windows XP on your SATA HDDs with RAID functions,

you will need to make an SATA driver diskette before you start

the OS installation.

STEP1: Insert the ASRock Support CD into your optical drive to

boot your system. (Do NOT insert any floppy diskette

into the floppy drive at this moment!)

STEP2: During POST at the beginning of system boot-up, press

<F11> key, and then a window for boot devices

selection appears. Please select CD-ROM as the boot

device.

STEP3: When you see the message on the screen, “Do you

want to generate Serial ATA driver diskette [YN]?”,

press <Y>.

STEP4: Then you will see these messages,

Please insert a diskette into the floppy drive.

WARNING! Formatting the floppy diskette will

lose ALL data in it!

Start to format and copy files [YN]?

Please insert a floppy diskette into the floppy drive, and

press <Y>.

STEP5: The system will start to format the floppy diskette and

copy SATA drivers into the floppy diskette.

Once you have the SATA driver diskette ready, you may start to

install Windows 2000 / Windows XP on your system directly

without setting the RAID configuration on your system, or you

may start to use “RAID BIOS Setting Utility” in the section 2.3 to

set RAID 0 / RAID 1 / JBOD configuration before you install the OS.

You may also set the RAID configuration by using “RAID Utility for

Windows” in Windows environment. Please refer to the document

in the Support CD, “Guide to RAID Utility for Windows”, which is

located in the folder at the following path:

.. \ RAID Utility for Windows

2. Guide to RAID Configurations

2.1 Introduction of RAID

This motherboard adopts MCP-RAID south bridge chipset that

integrates RAID controller supporting RAID 0 / RAID 1 / RAID 0+1 /

JBOD function with two independent Serial ATA (SATA) channels.

This section will introduce the basic knowledge of RAID, and the

guide to configure RAID 0, RAID 1, RAID 0+1, and JBOD settings.

RAID

The term “RAID” stands for “Redundant Array of Independent

Disks”, which is a method combining two or more hard disk drives

into one logical unit. For optimal performance, please install

identical drives of the same model and capacity when creating a

RAID set.

RAID 0 (Data Striping)

RAID 0 is called data striping that optimizes two identical hard disk

drives to read and write data in parallel, interleaved stacks. It will

improve data access and storage since it will double the data

transfer rate of a single disk alone while the two hard disks

perform the same work as a single drive but at a sustained data

transfer rate.

WARNING!!

Although RAID 0 function can improve the access performance, it

does not provide any fault tolerance. Hot-Plug any HDDs of the

RAID 0 Disk will cause data damage or data loss.

RAID 1 (Data Mirroring)

RAID 1 is called data mirroring that copies and maintains an

identical image of data from one drive to a second drive. It

provides data protection and increases fault tolerance to the

entire system since the disk array management software will

direct all applications to the surviving drive as it contains a

complete copy of the data in the other drive if one drive fails.

JBOD (Spanning)

A spanning disk array is equal to the sum of all drives. Spanning

stores data onto a drive until it is full then proceeds to store files

onto the next drive in the array. When any member disk fails, it

will affect the entire array. JBOD is not really a RAID, and it does

not support fault tolerance.

2.2 RAID Configurations Precautions

1. Please use two new drives if you are creating a RAID 0

(striping) array for performance. It is recommended to

use two SATA drives of the same size. If you use two

drives of different sizes, the smaller capacity hard disk

will be the base storage size for each drive. For

example, if one hard disk has an 80GB storage capacity

and the other hard disk has 60GB, the maximum storage

capacity for the 80GB-drive becomes 60GB, and the

total storage capacity for this RAID 0 set is 120GB.

2. You may use two new drives, or use an existing drive

and a new drive to create a RAID 1 (mirroring) array for

data protection (the new drive must be of the same size

or larger than the existing drive). If you use two drives

of different sizes, the smaller capacity hard disk will be

the base storage size. For example, if one hard disk has

an 80GB storage capacity and the other hard disk has

60GB, the maximum storage capacity for the RAID 1 set

is 60GB.

3. Please verify the status of your hard disks before you

set up your new RAID array.
