Chapter 2 BIOS Setup

BIOS (Basic Input and Output System) includes a CMOS SETUP utility which allows user to configure
required settings or to activate certain system features.
The CMOS SETUP saves the configuration in the CMOS SRAM of the motherboard.
When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS
SRAM.
When the power is turned on, pushing the <Del> button during the BIOS POST (Power-On Self Test) will
take you to the CMOS SETUP screen. You can enter the BIOS setup screen by pressing "Ctrl + F1".
When setting up BIOS for the first time, it is recommended that you save the current BIOS to a disk in the
event that BIOS needs to be reset to its original settings. If you wish to upgrade to a new BIOS, either
Gigabyte's Q-Flash or @BIOS utility can be used.
Q-Flash allows the user to quickly and easily update or backup BIOS without entering the operating system.
@BIOS is a Windows-based utility that does not require users to boot to DOS before upgrading BIOS but
directly download and update BIOS from the Internet.

4-1-2 Xpress Recovery2 Introduction

Xpress Recovery2 is designed to provide quick backup and restora­tion of hard disk data. Supporting Microsoft operating systems including
Windows XP/2000/NT/98/Me and DOS, and file systems including
FAT16, FAT32, and NTFS, Xpress Recovery2 is able to back up data

on hard disks on PATA and SATA IDE controllers. After Xpress Recovery2 is executed from CD-ROM
for the first time, it will stay permanent in your hard disk. If you wish to run Xpress Recovery2 later, you
can simply press F9 during system bootup to enter Xpress Recovery2 without the CD-ROM.

System requirements:

1. Intel x86 platforms

2. At least 64M bytes of system memory

3. VESA-supported VGA cards

How to use the Xpress Recovery2

Initial access by booting from CD-ROM and subsequent access by pressing the F9 key:
Steps: After entering BIOS Setup, go to Advanced BIOS Feature and set to boot from CD-ROM. Save

the settings and exit the BIOS Setup. Insert the provided driver CD into your CD-ROM drive. Upon
system restart, the message which says "Boot from CD/DVD:" will appear in the bottom left corner
of the screen. Press any key to enter Xpress Recovery2.
After the steps above are completed, subsequent access to Xpress Recovery2 can be made
by simply pressing the <F9> key during system power-on.

1. If you have already entered Xpress Recovery2 by booting from the CD-ROM, you can
enter Xpress Recovery2 by pressing the <F9> key in the future.

2. System storage capacity and the reading/writing speed of the hard disk will affect
the data backup speed.

3. It is recommended that Xpress Recovery2 be immediately installed once you com­plete installations of OS and all required drivers as well as software.

GA-8S648FX-775(-C) Motherboard - 50 -

The Main Screen of Xpress Recovery2

1. RESTORE:

Restore the backed-up data to your hard disk.
(This button will not appear if there is no backup
file.)

2. BACKUP:

Back up data from hard disk.

3. REMOVE:

Remove previously-created backup files
to release disk space.
(This button will not appear if there is no backup
file.)

4. REBOOT:

Exit the main screen and restart the system.

Limitations:

1. Not compatible to Xpress Recovery.

2. For the use of Xpress Recovery2, a primary partition must be reserved.

3. Xpress Recovery2 will store the backup file at the end of the hard disk, so free space available
on the hard disk for the backup file must be allocated in advance. (A minimum 4GB is recom­mended but the actual space is dependent on the size of the data to be backed up)

4. Capable of backing up hard disks installed with Windows operating systems including DOS and
Windows XP/2000/NT/9x/Me.

5. USB hard disks are currently not supported.

6. Does not support RAID/AHCI (class code 0104/0106) hard disks.

7. Capable of backing up and restoring only the first physical hard disk.

Hard disks detection sequence is as follows:

a. PATA IDE primary channel
b. PATA IDE secondary channel
c. SATA IDE channel 1
d. SATA IDE channel 2
e. SATA IDE channel 3
f. SATA IDE channel 4

Precautions:

1. When using hard disks with more than 128G under Windows 2000, be sure to execute the
EnableBigLba.exe program from the driver CD before data backup.

2. It is normal that data backup takes longer time than data restoration.

3. Xpress Recovery2 is compliant with the GPL regulations.

4. On a few motherboards based on Nvidia chipsets, BIOS update is required for Xpress Recovery2
to correctly identify RAID and SATA IDE mode. Please contact your motherboard manufacturer.

5. Xpress Recovery2 supports only PATA hard disks and not SATA hard disks on the following
motherboards (As this is a BIOS-related issue, it can be solved by BIOS update)

4-1-3 Flash BIOS Method Introduction

Method 1 : Q-FlashTM Utility

Q-FlashTM is a BIOS flash utility embedded in Flash ROM. With this utility,
users only have to stay in the BIOS menu when they want to update

BIOS. Q-Flash?allows users to flash BIOS without any utility in DOS or
Windows. Using Q-FlashTM indicating no more fooling around with any complicated instructions and
operating system since it is in the BIOS menu.

Please note that because updating BIOS has potential risk, please do it with caution!! We are
sorry that Gigabyte Technology Co., Ltd is not responsible for damages of system because of
incorrect manipulation of updating BIOS to avoid any claims from end-users.

4-1-4 Serial ATA BIOS Setting Utility Introduction

RAID Levels

RAID (Redundant Array of Independent Disks) is a method of combining two 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 SiS® 964 chipset supports are RAID 0 and RAID

1.

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 16KB to 256KB. 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.

English

Appendix- 61 -

English

Please follow the steps below to construct a complete RAID array:

1) Have ready your hard drives for RAID construction.

Note: To achieve best performance, it is recommended that the hard drives used are of similar
make and storage capacity.

2) Please attach the hard drive connectors to their appropriate location on the motherboard ie. IDE,

SCSI, or SATA.

3) Enter the motherboard BIOS and locate RAID setup (Please refer to the section on Integrated

Peripherals).

4) Enter RAID setup in the BIOS and select the RAID type (For instance, press Ctrl-S to enter SiS

RAID BIOS).

5) Complete driver installation.

6) Complete RAID utility installation.
More information is provided on the steps below.

Configuring the SiS RAID BIOS

Installing the RAID Drivers

To install Windows 2000/XP onto a Serial ATA hard disk sucessfully, you need to install required driver for
the SATA controller on your motherboard during OS installation. Without the driver, the hard disk may not be
recognized during the Windows setup process.
First of all, you have to copy the driver for the SATA controller on your motherboard from the motherboard
driver CD to a floppy disk. See the instructions below about how to copy the driver.

Step 1:
Find an available Operation System and insert the motherboard driver CD into the CD-ROM drive. The
installation utility will appear automatically soon after you insert the driver CD. Quit the installation utility first.
Insert a blank formatted floppy disk into the floppy disk drive.

Step 2:
Go to My Computer and right-click the CD-ROM icon (This procedure assumes Drive D) and select Open.
Then you will see folders and files contained in the driver CD. Double-click the BootDrv folder icon and
select MENU.exe (refer to Figure10).

(Note)

English

Figure 10

Figure 11

Step 3:
A MS-DOS prompt screen will appear. Information on all chipsets should be listed on the screen (Refer to
Figure 11), please select the proper chipset model.

Your system will then automatically zip and transfer this driver file to the floppy disk.

After you complete the steps, boot from the Windows CD to install the RAID drivers.
When install Windows 2000 or Windows XP from HDDs in serial ATA controller, press F6 as Win2000 or
XP boots up, then supply serial ATA controller driver by this floppy disk. Follow on-screen instructions to
complete installation.
(Each time you add a new hard drive to a RAID array, the RAID driver will have to be installed under
Windows once for that hard drive. After that, the driver will not have to be installed.)

Note: In the menu list, IAA_RAID refers to Intel ICH5R chipset.

4-2 Troubleshooting

Below is a collection of general asked questions. To check general asked questions based on a specific
motherboard model, please log on to http://www.gigabyte.com.tw

Question 1: I cannot see some options that were included in previous BIOS after updating BIOS. Why?
Answer: Some advanced options are hidden in new BIOS version. Please press Ctrl and F1 keys after
entering BIOS menu and you will be able to see these options.

Questions 2: Why is the light of my keyboard/optical mouse still on after computer shuts down?
Answer: In some boards, a small amount of electricity is kept on standby after computer shuts down
and that's why the light is still on.

Question 3: How do I clear CMOS?
Answer: If your board has a Clear CMOS jumper, please refer to the Clear CMOS steps in the manual.
If your board doesn't have such jumper, you can take off the on-board battery to leak voltage to clear
CMOS. Please refer to the steps below:

Steps:

1. Turn off power.

2. Disconnect the power cord from MB.

3. Take out the battery gently and put it aside for about 10 minutes (Or you can use a metal object
to connect the positive and negative pins in the battery holder to makethem short for
one minute).

4. Re-insert the battery to the battery holder.

5. Connect power cord to MB again and turn on power.

6. Press Del to enter BIOS and load Fail-Safe Defaults(or load Optimized Defaults).

7. Save changes and reboot the system.

Question 4: Why do I still get a weak sound after turning up the speaker to the maximum volume?
Answer: Please make sure the speaker you are using is equipped with an internal amplifier. If not,
please change another speaker with power/amplifier and try again later.

Question 5: Sometimes I hear different continuous beeps from computer after system boots up. What do
these beeps usually stand for?
Answer: The beep codes below may help you identify the possible computer problems. However,
they are only for reference purposes. The situations might differ from case to case.
