1-2 Chipset Overview
The Intel® G41 Express Chipset, combined wtih the Intel CoreTM 2 processor fam-
ily and the ICH7 I/O controller offers an uncomparable match to deliver new digital
capabilities for the home consumer. Also included with the C2G41 motherboard
is the Intel Graphics Media Accelerator (Intel GMA X4500) for built-in support for
smooth high-denition video playback without the need for third-party accelerators
or decoders.
Intel Core 2 processor Support
The Intel G41 Express chipset fully supports the Intel Core 2 Duo/Quad/ Pentium
processor and Intel Celeron processor. Among the features supported are:
- 1333/1066/800 MHz System Bus
- Fast Memory Access
- Dual-Channel DDR3 Memory
- Intel Flex Memory Technology
- Intel Clear Video Technology
- HDMI Interface
- Intel High Denition Audio
Intel ICH7 System Features
The I/O Controller (ICH7) provides the data buffering and interface arbitration re-
quired for the system to operate efciently. It also provides the bandwidth needed
for the system to maintain its peak performance. The ICH7 supports PCI slots, Se-
rial ATA ports, USB 2.0 ports and dual channel IDE devices. In addition, the ICH7
offers the Intel Matrix Storage Technology which provides various RAID options for
data protection and rapid data access. It also supports the next generation of client
management through the use of PROActive technology in conjunction with Intel's
next generation Gigabit Ethernet controllers.
Note: For detailed information, please refer to Intel's website and search for the
keywords "G41 Express".

C2G41 User’s Manual
1-3 Recovery from AC Power Loss
BIOS provides a setting for you to determine how the system will respond when
AC power is lost and then restored to the system. You can choose for the system
to remain powered off (in which case you must hit the power switch to turn it back
on) or for it to automatically return to a power on state. See the Power Lost Control
setting in the BIOS chapter of this manual to change this setting. The default set-
ting is Last State.
1-4 PC Health Monitoring
The motherboard has an onboard System Hardware Monitor chip that supports PC
health monitoring.
The onboard voltage monitor will scan the voltages of the Onboard Voltage Moni-
tors for the Onboard voltage monitors for the CPU core, G41 core and memory
voltage, +5V, +12V and +3.3V continuously. Once a voltage becomes unstable, it
will give a warning or send an error message to the screen. Users can adjust the
voltage thresholds to dene the sensitivity of the voltage monitor by using SuperO
Doctor III.
1-5 ACPI Features
ACPI stands for Advanced Conguration and Power Interface. The ACPI specica-
tion denes a exible and abstract hardware interface that provides a standard
to integrate power management features throughout a PC system, including its
hardware, operating system and application software. This enables the system to
automatically turn on and off peripherals such as CD-ROMs, network cards, hard
disk drives and printers. This also includes consumer devices connected to the PC
such as VCRs, TVs, telephones and stereos.
In addition to enabling operating system-directed power management, ACPI pro-
vides a generic system event mechanism for Plug and Play and an operating- sys-
tem-independent interface for conguration control. ACPI leverages the Plug and
Play BIOS data structures while providing a processor architecture-independent
implementation that is compatible with Windows 2000, Windows XP, Windows 2003,
Windows 2003 Servers.
Enhanced Power Management
The onboard ICH7 chip provides advanced power management functions that will
greatly improve the performance of various low-power (suspend) states and en-

Chapter 1: Introduction
1-11
hance clock control. A hardware-based component provides software-independent
thermal management that is compatible with the ACPI Revision 3.0a.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.
1-6 Power Supply
As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates of 1 GHz and faster.
The C2G41 accommodates 12V ATX power supplies. Although most
power supplies generally meet the specications required by the CPU, some are
inadequate. A 2-Amp of current supply on a 5V Standby rail is strongly recom-
mended.
It is strongly recommended that you use a high quality power supply that meets
12V ATX power supply Specication 1.1 or above. It is also required that the 12V
8-pin power connection (JPW2) be used for high-load congurations. In areas where
noisy power transmission is present, you may choose to install a line lter to shield
the computer from noise. It is recommended that you also install a power surge
protector to help avoid problems caused by power surges.
1-7 Versatile Media Capabilities
HighDenitionAudio
The High Denition Audio Controller embedded in the ICH7 delivers up to 4 codecs
that can be used for different types of codecs, such as audio and modem codecs.
Operating at 3.3V or 1.5V, the embedded Audio Controller supports a multi-channel
audio stream, 32-bit sample depth, up to 192 kHz of same rate, and can be used with
a variety of microphones for input. With these versatile audio capabilities built in, the
C2G41 provides the user with a surreal audio experience that is larger than life.

1-12
C2G41 User’s Manual
HighDenitionVideo(HDMI)
The C2G41 also includes a High-Denition Multimedia Interface (HDMI) connector
on the motherboard. This connector transmits digital video signals, providing superb
multimedia interface support.
With these versatile audio and video capabilities built in, this motherboard provides
the user with a state of the art audio/video experience that is larger than life.
1-8 Super I/O
The C2G41 features the ITE IT8720F-JX LPC I/O and provides two high-speed,
16550 compatible serial communication ports (UARTs). Each UART includes a
16-byte send/receive FIFO, a programmable baud rate generator, complete modem
control capability and a processor interrupt system. Both UARTs provide legacy
speed with baud rate of up to 115.2 Kbps as well as an advanced speed with baud
rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems.
The Super I/O provides functions that comply with the ACPI (Advanced Congura-
tion and Power Interface), which includes support of legacy and ACPI power man-
agement through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.

Installation
2-1 Electro-Static Sensitive Devices
Electro-static Discharge (ESD) can damage electronic components. To prevent dam-
age to your system board, it is important to handle it very carefully. The following
measures are generally sufcient to protect your equipment from ESD.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the board from the antistatic
bag.
• Handle the board by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the motherboard and peripherals back into their antistatic bags when not in
use.
• For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the motherboard.
• Use only the correct type of onboard CMOS battery as specied by the manu-
facturer. Do not install the onboard battery upside down to avoid possible explo-
sion.
Unpacking
The motherboard is shipped in antistatic packaging to avoid static damage. When
unpacking the board, make sure the person handling it is static protected.

2-2 Motherboard Installation
All motherboards have standard mounting holes to t different types of chassis.
Make sure that the locations of all the mounting holes for both motherboard and
chassis match. Although a chassis may have both plastic and metal mounting fas-
teners, metal ones are highly recommended because they ground the motherboard
to the chassis. Make sure that the metal standoffs click in or are screwed in tightly.
Then use a screwdriver to secure the motherboard onto the motherboard tray.
