1.4 Before you proceed

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

1. Unplug the power cord from the wall socket before touching any

component.

2. Use a grounded wrist strap or touch a safely grounded object or to a metal

object, such as the power supply case, before handling components to

avoid damaging them due to static electricity.

3. Hold components by the edges to avoid touching the ICs on them.

4. Whenever you uninstall any component, place it on a grounded antistatic

pad or in the bag that came with the component.

5. Before you install or remove any component, ensure that the ATX power

supply is switched off or the power cord is detached from the power supply.

Failure to do so may cause severe damage to the motherboard,

peripherals, and/or components.

Onboard LED

The motherboard comes with a stand-by power LED. When lit, this green LED

indicates that the system is ON, in sleep mode, or in soft-off mode, a reminder that

you should shut down the system and unplug the power cable before removing or

plugging in any motherboard component. The illustration below shows the location

of the onboard LED.

1.9 Jumpers

1. Clear RTC RAM (CLRTC)

This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS.

You can clear the CMOS memory of date, time, and system setup parameters

by erasing the CMOS RTC RAM data. The RAM data in CMOS, that include

system setup information such as system • words, is powered by the onboard

button cell battery.

To erase the RTC RAM:

1. Turn OFF the computer and unplug the power cord.

2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on

pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2.

3. Plug the power cord and turn ON the computer.

4. Hold down the <Del> key during the boot process and enter BIOS setup to

re-enter data.

Except when clearing the RTC RAM, never remove the cap on the jumper

default position. Removing the cap will cause system boot failure!

2.2 BIOS Setup program

This motherboard supports a programmable LPC chip that you can update using

the provided utility described in section “2.1 Managing and updating your BIOS.”

Use the BIOS Setup program when you are installing a motherboard, reconfiguring

your system, or prompted to “Run Setup”. This section explains how to configure

your system using this utility.

Even if you are not prompted to use the Setup program, you may want to change

the configuration of your computer in the future. For example, you may want to

enable the security password feature or change the power management settings.

This requires you to reconfigure your system using the BIOS Setup program so

that the computer can recognize these changes and record them in the CMOS

RAM of the LPC.

The LPC on the motherboard stores the Setup utility. When you start up the

computer, the system provides you with the opportunity to run this program. Press

<Del> during the Power-On Self Test (POST) to enter the Setup utility. Otherwise,

POST continues with its test routines.

If you wish to enter Setup after POST, restart the system by pressing

<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis. You can

also restart by turning the system off and then back on. Do this last option only if

the first two failed.

The Setup program is designed to make it as easy to use as possible. It is a menu-

driven program, which means you can scroll through the various sub-menus and

make your selections from the available options using the navigation keys.

The default BIOS settings for this motherboard apply for most conditions to

ensure optimum performance. If the system becomes unstable after changing

any BIOS settings, load the default settings to ensure system compatibility and

stability. Select the Load Default Settings item under the Exit Menu. See

section “2.7 Exit Menu.”

The BIOS setup screens shown in this chapter are for reference purposes only,

3.3 RAID configurations

The SIS 965L southbridge comes with a RAID controller that allows you to

configure Serial ATA hard disk drives as RAID sets. The motherboard supports the

following RAID configurations.

RAID 0 (Data striping) optimizes two identical hard disk drives to read and write

data in parallel, interleaved stacks. Two hard disks perform the same work as a

single drive but at a sustained data transfer rate, double that of a single disk alone,

thus improving data access and storage. Use of two new identical hard disk drives

is required for this setup.

RAID 1 (Data mirroring) copies and maintains an identical image of data from one

drive to a second drive. If one drive fails, the disk array management software

directs all applications to the surviving drive as it contains a complete copy of the

data in the other drive. This RAID configuration provides data protection and

increases fault tolerance to the entire system. Use two new drives or use an

existing drive and a new drive for this setup. The new drive must be of the same

size or larger than the existing drive.

JBOD (Spanning) stands for Just a Bunch of Disks and refers to hard disk drives

that are not yet configured as a RAID set. This configuration stores the same data

redundantly on multiple disks that appear as a single disk on the operating system.

Spanning does not deliver any advantage over using separate disks

independently and does not provide fault tolerance or other RAID performance

benefits.

If you want to boot the system from a hard disk drive included in a RAID set,

copy first the RAID driver from the support CD to a floppy disk before you install

an operating system to a selected hard disk drive. Refer to section “3.4 Creating

a RAID driver disk” for details.

3.3.1 Installing hard disks

The motherboard supports Serial ATA hard disk drives. For optimal performance,

install identical drives of the same model and capacity when creating a disk array.

Installing Serial ATA (SATA) hard disks

To install the SATA hard disks for a RAID configuration:

1. Install the SATA hard disks into the drive bays.

2. Connect the SATA signal cables.

3. Connect a SATA power cable to the power connector on each drive.
