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.

Chapter 4 Appendix
4-1Unique Software Utilities
(Not all model support these Unique Software Utilities, please check your MB features.)
U-PLUS D.P.S. (Universal Plus Dual Power System)
The U-Plus Dual Power System (U-Plus DPS) is a revolutionary eight-phase power circuit
built for ultimate system protection. Designed to withstand varying current levels and
changes, the U-Plus D.P.S. provides an immensely durable and stable power circuit to the
CPU for solid system stability. These characteristics make it the ideal companion with the
latest LGA775 Intel
blue LED's are mounted on the U-Plus D.P.S. for intelligent indication of system loading.
M.I.T. (Motherboard Intelligent Tweaker)
Motherboard Intelligent Tweaker (M.I.T.) allows user to access and change BIOS feature
settings with relative speed and ease. Through GIGABYTE M.I.T. feature the user is no
longer required to switch into different modes within BIOS setup in order to change system
settings such as the CPU system bus, memory timings or to enabled Gigabyte's unique
C.I.A. 2 and M.I.B. 2 features. M.I.T.'s integration of all platform performance settings into
a single mode now gives any user the ability to control and enhance their computer system
to the desired level.
C.I.A.2 (CPU Intelligent Accelerator 2)
GIGABYTE CPU Intelligent Accelerator 2(C.I.A. 2) is designed to automatically adjust CPU
computing power to maximize system performance. When enabled, the program detects
the current CPU loading and automatically accelerates the CPU computing performance to
allow for a faster and smoother execution of programs. When the function is disabled, the
CPU is returned to its initial status.
M.I.B.2 (Memory Intelligent Booster 2)
Built on the original M.I.B., the new Memory Intelligent Booster 2 (M.I.B. 2) is designed
especially to maximize memory performance and boost memory bandwidth up to 10%.
With added branded memory module information, users are able to optimize memory
performance by selecting from a recommended memory module list.
S.O.S. (System Overclock Saver)
System Overclock Saver (S.O.S.) is a unique feature that eliminates system boot-up errors
resulting from system over-enhancement by the user. With GIGABYTE's proprietary
S.O.S. feature, users no longer need to open up the PC chassis and short-circuit the "Clear
CMOS" pins or the battery on the motherboard to reset the system back to factory default
settings. Instead, S.O.S. automatically resets the overclocked system settings back to their
factory defaults to provide a more user-friendly and reliable platform for users.
Download Center
Download Center allows users to quickly download and update their BIOS as well as the
latest drivers for their system. Download Center automatically runs a system check of the
user PC and provides the user with the current system information as well as displaying a
detailed list of all new drivers with the option for download.
C.O.M. (Corporate Online Management)
A web-based system management tool that allows system hardware information such as
CPU, memory, graphics card, etc. to be monitored and controlled via the Internet, C.O.M.
allows corporate MIS engineers to easily maintain corporate computers such as providing

4-2Troubleshooting
Below is a collection of general asked questions. To check general asked questions based on a specific
motherboard model, please log on to http://tw.giga-byte.com/faq/faq.htm
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.
7. Save changes and reboot the system.
Question 4: Why does system seem unstable after updating BIOS?
Answer: Please remember to load Fail-Safe Defaults (Or Load BIOS Defaults) after flashing BIOS. However,
if the system instability still remains, please clear CMOS to solve the problem.
Question 5: 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 6: How do I disable onboard VGA card in order to add an external VGA card?
Answer: Gigabyte motherboards will auto-detect the external VGA card after it is plugged in, so you don't
need to change any setting manually to disable the onboard VGA.
GA-8I915G Duo Motherboard- 72 -
Question 7: Why cannot I use the IDE 2?
Answer: Please refer to the user manual and check whether you have connected any cable that is not
provided with the motherboard package to the USB Over Current pin in the Front USB Panel. If the cable is
your own cable, please remove it from this pin and do not connect any of your own cables to it.
Question 8: 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.
