Hardware Setup

CPU (Central Processing Unit)

This mainboard supports Intel® Pentium 4 processor in LGA 775 package. When you

are installing the CPU, make sure to install the cooler to prevent overheating.

If you do not have the CPU cooler, contact your dealer to purchase and install them

before turning on the computer.

For the latest information about CPU, please visit http://www.msi.com.tw/program/

products/mainboard/mbd/pro_mbd_cpu_support.php.

Important

1. Overheating will seriously damage the CPU and system. Always make

sure the cooling fan can work properly to protect the CPU from overheating.

2. Make sure that you apply an even layer of heat sink paste (or thermal tape)

between the CPU and the heatsink to enhance heat dissipation.

3. While replacing the CPU, always turn off the ATX power supply or unplug

the power supply’s power cord from the grounded outlet first to ensure the

safety of CPU.

-DDRII modules are not interchangeable with DDR and the DDRII standard is

not backwards compatible. You should always install DDRII memory mod-

ules in the DDRII DIMM slots and DDR memory modules in the DDR DIMM

slots.

-To enable successful system boot-up, always insert the memory modules

into the DIMM1 first.

Installing DDRII Modules

1. The memory module has only one notch on the center and will only fit in the right

orientation.

2. Insert the memory module vertically into the DIMM slot. Then push it in until the

golden finger on the memory module is deeply inserted in the DIMM slot.

3. The plastic clip at each side of the DIMM slot will automatically close.

Introduction

This section gives a brief introduction on the RAID-related background knowledge and

a brief introduction on VIA SATA RAID Host Controller. For users wishing to install their

VIA SATA RAID driver and RAID software, proceed to Driver and RAID Software

Installation section.

RAID Basics

RAID (Redundant Array of Independent Disks) is a method of combining two or more

hard disk drives into one logical unit. The advantage of an Array is to provide better

performance or data fault tolerance. Fault tolerance is achieved through data redundant

operation, where if one drives fails, a mirrored copy of the data can be found on

another drive. This can prevent data loss if the operating system fails or hangs. The

individual disk drives in an array are called “members”. The configuration information of

each member is recorded in the “reserved sector” that identifies the drive as a member.

All disk members in a formed disk array are recognized as a single physical drive to the

operating system.

Hard disk drives can be combined together through a few different methods. The

different methods are referred to as different RAID levels. Different RAID levels

represent different performance levels, security levels and implementation costs. The

RAID levels which the VIA VT8237A / VT8237S SATA RAID Host Controller supports are

RAID 0 and RAID 1. The table below briefly introduced these RAID levels.

RAID Level

No. of Drives

Capacity Benefits

RAID 0

(Striping)

2 Smallest size * 2 Highest performance without

data protection

RAID 1

(Mirroring)

2 Smallest size Data protection

RAID 0 (Striping)

RAID 0 reads and writes sectors of data interleaved between multiple drives. If

any disk member fails, it affects the entire array. The disk array data capacity is equal

to the number of drive members times the capacity of the smallest member. The striping

block size can be set from 4KB to 64KB. RAID 0 does not support fault tolerance.

RAID 1 (Mirroring)

RAID 1 writes duplicate data onto a pair of drives and reads both sets of data in

parallel. If one of the mirrored drives suffers a mechanical failure or does not respond,

the remaining drive will continue to function. Due to redundancy, the drive capacity of

the array is the capacity of the smallest drive. Under a RAID 1 setup, an extra drive

called the .spare drive. can be attached. Such a drive will be activated to replace a

failed drive that is part of a mirrored array. Due to the fault tolerance, if any RAID 1 drive

fails, data access will not be affected as long as there are other working drives in the

array.

Create Disk Array

Use the up and down arrow keys to select the Create Array command and press

<Enter>.

Select Array Mode and press <Enter>, a list of array modes will appear. Highlight the

target array mode that you want to create, and press <Enter> to confirm the selection.

If RAID 1 is selected, an option list will popup and enable the users to select Create

and duplicate which allows BIOS copy the data from the source to the mirroring drive.

The “Channel”, “Drive Name”, “Mode” and “Size (GB)” in the following

example might be different from your system.

VIA VT8237A / VT8237S SATA RAID Introduction

If user selects a RAID 0 array in step 2, the block size of the array can also be selected.

Use the arrow key to highlight Block Size and press <Enter>, then select a block size

from the popup menu. The block size can be 4KB to 64KB.

After array mode is selected, there are two methods to create a disk array. One

method is “Auto Setup” and the other one is “Select Disk Drives”. Auto Setup

allows BIOS to select the disk drives and create arrays automatically, but it does not

duplicate the mirroring drives even if the user selected Create and duplicate for

RAID 1. It is recommended all disk drives are new ones when wanting to create an

array. Select Disk Drives lets the user select the array drives by their requirements.

When using Select Disk Drives, the channel column will be activated. Highlight the

target drives that you want to use and press <Enter> to select them. After all drives

have been selected, press <Esc> to go back to the creation steps menu.

Delete Disk Array

A RAID can be deleted after it has been created. To delete a RAID, use the following

steps:

1. Select Delete Array in the main menu and press <Enter>. The channel column

will be activated.

2. Select the member of an array that is to be deleted and press <Enter>. A warning

message will show up, press Y to delete or press N to cancel.

Deleting a disk array will destroy all the data on the disk array except RAID 1

arrays. When a RAID is deleted, the data on these two hard disk drives will be

reserved and become two normal disk drives.

Even though 64KB is the recommended setting for most users, you

should choose the block size value which is best suited to your specific

RAID usage model.

4KB: For specialized usage models requiring 4KB blocks

8KB: For specialized usage models requiring 8KB blocks

16KB: Best for sequential transfers

32KB: Good for sequential transfers

64KB: Optimal setting

Use the arrow key to highlight Start Create Process and press <Enter>. A warning

message will appear, Press Y to finish the creation, or press N to cancel the creation.

Important note: All existing content in the hard drive will be destroyed after array

creation.

Create and Delete Spare Hard Drive

If a RAID 1 array is created and there are drives that do not belong to other arrays, the

one that has a capacity which is equal to or greater than the array capacity can be

selected as a spare drive for the RAID 1 array. Select Create/Delete Spare and

press <Enter>, the channel column will then be activated. Select the drive that you

want to use as a spare drive and press <Enter>, the selected drive will be marked as

Spare. The spare drive cannot be accessed in an OS.

To delete a spare drive, highlight Create/Delete Spare and press <Enter>. The spare

drive will be highlighted, press <Enter> to delete the spare drive.

Rebuild Broken RAID 1 Array

When booting up the system, BIOS will detect if any member disk drives of RAID has

failed or is absent. If BIOS detects any disk drive failures or missing disk drives, the

status of the array will be marked as broken.

If BIOS detects a broken RAID 1 array but there is a spare hard drive available for

rebuilding the broken array, the spare hard drive will automatically become the mirroring

drive. BIOS will show a main interface just like a duplicated RAID 1. Selecting Continue

to boot enables the user to duplicate the array after booting into operating system.

If BIOS detects a broken RAID 1 array but there is no spare hard drive available for

rebuilding the array, BIOS will provide several operations to solve such problem.

Duplicate Critical RAID 1 Array

When booting up the system, BIOS will detect if the RAID 1 array has any inconsisten-

cies between user data and backup data. If BIOS detects any inconsistencies, the

status of the disk array will be marked as critical, and BIOS will prompt the user to

duplicate the RAID 1 in order to ensure the backup data consistency with the user data.

If user selects Continue to boot, it will enable duplicating the array after booting into

OS.
