2. Central Processing Unit (CPU)
The motherboard comes with a surface mount 479-pin Zero Insertion Force
(ZIF) socket designed for the Intel® Pentium® M / Dothan® processor (supports
mPGA479M, Micro-FCPGA).
Note the marked corner (with gold
triangle) on the CPU. This mark should
match a specific corner on the socket
to ensure correct installation.
Gold mark
2.1 Enhanced Intel
SpeedStep® Technology (EIST)
• The motherboard comes with a BIOS file that supports EIST.
• Visit www.intel.com for more information on the EIST feature.
System requirements
Before using EIST, check your system if it meets the following
requirements:
• Intel® Yonah® Mobile processor with EIST support
• BIOS file with EIST support
• Operating system with EIST support (Windows® XP SP2/Windows® Server
2003 SP1/Linux 2.6 kernel or later versions)
Using the EIST
To use the EIST feature:
1. Turn on the computer, then enter the BIOS Setup.
2. Go to the Advanced Menu, highlight CPU Configuration,then press
<Enter>.
3. Set the Intel(R) SpeedStep Technology item
to [Automatic], then press <Enter>.
4. Press <F10> to save your changes and exit
the BIOS setup.
5. After the computer restarts, right click on
a blank space on the desktop, then select
Properties from the pop-up menu.
6. When the Display Properties window appears,
click the Screen Saver tab.

2.2 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
Socket lever
Make sure that the socket lever
is lifted up to 90 ~ 100 angle;
otherwise, the CPU does not fit
in completely.
90~100 angle
1. Unlock the socket by pressing the
lever sideways , then lift it up to a
90 ~ 100 angle.
8. On the Power schemes section, click , then select any option except
Home/Office Desktop or Always On.
9. Click Apply, then click OK.
10. Close the Display Properties window.
After you adjust the power scheme, the CPU
internal frequency slightly decreases when
the CPU loading is low.
The screen displays and procedures
may vary depending on the operating
system.

3. Position the CPU above the
socket such that its marked
corner matches the base of the
socket lever.
4. Carefully insert the CPU into the
socket until it fits in place. Gold Mark
The CPU fits in only one correct orientation. DO NOT force the CPU into
the socket to prevent bending the connectors on the socket and damaging
the CPU!
5. When the CPU is in place , push
down the socket lever to secure
the CPU. The lever clicks on the
side tab to indicate that it is
locked.
After installation, make sure to plug-in the 24-pin ATX power cable to
the motherboard.
This motherboard supports Dothan® M 3 series or Pentium® M 7 series
CPUs.

3. System memory
The motherboard comes with two Double Data Rate2 (DDR2) Dual Inline
Memory Module (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a
240-pin footprint compared to the 184-pin DDR DIMMs are notched differently
to prevent installation on a DDR DIMM socket.
The figure illustrates the location of the DDR2 DIMM sockets.
3.1 Memory configurations
You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into
the DIMM sockets using the memory configurations in this section.
• Installing DDR2 DIMMs other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of
the recommended configurations on the next page.
• Install only identical (the same type and size) DDR2 DIMM pairs
using the recommended configurations.
• Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table on the next page
• Due to chipset resource allocation, the system may detect less
than 2 GB system memory when you installed two 1 GB DDR2
memory modules.
• This motherboard does not support memory modules made up of
128 Mb chips or double sided x 16 memory modules.

3.2 Installing a DDR2 DIMM
3. Firmly insert the DIMM into the
socket until the retaining clips
snap back in place and the DIMM
is properly seated.
To install a DIMM:
1. Unlock a DIMM socket by pressing
the retaining clips outward.
Locked retaining clip
Make sure to unplug the power supply before adding or removing DIMMs
or other system components. Failure to do so may cause severe damage
to both the motherboard and the components.
A DDR2 DIMM is keyed with a notch so that it fits in only one direction. DO
NOT force a DIMM into a socket to avoid damaging the DIMM.

5. Jumper
1. Clear RTC RAM (3-pin 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 onboard button
cell battery powers the RAM data in CMOS, which include system setup
information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 2-3 (Normal) to pins 1-2 (Clear
CMOS). Keep the cap on pins 2-3 for about 5~10 seconds, then
move the cap back to pins 2-3.
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 from the
default position. Removing the cap will cause system boot failure!

6. Hold down the <F1> key during the boot process and enter BIOS
setup to verify that the password has been cleared.
2. Clear password (3-pin CLPWD)
This jumper allows you to clear the password if you forgot your
password.
To erase the password:
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 2-3 (Normal) to pins 1-2 (Clear
Password).
3. Plug the power cord and turn ON the computer.

1. IDE connector (40-1 pin IDE1)
This connector is for an Ultra DMA 100/66 signal cable. The Ultra DMA
100/66 signal cable has three connectors: a blue connector for the
primary IDE connector on the motherboard, a black connector for an
Ultra DMA 100/66 IDE slave device (optical drive/hard disk drive), and
a gray connector for an Ultra DMA 100/66 IDE master device (hard disk
drive). If you install two hard disk drives, you must configure the second
drive as a slave device by setting its jumper accordingly. Refer to the
hard disk documentation for the jumper settings.
• Pin 20 on the IDE connector is removed to match the covered hole on
the Ultra DMA cable connector. This prevents incorrect insertion when
you connect the IDE cable.
• Use the 80-conductor IDE cable for Ultra DMA 100/66 IDE devices.
6.2 Internal connectors
This section describes and illustrates the internal connectors on the
motherboard.

2. ATX Micro-Fit power connectors (24-pin ATXPWR1)
These connectors are for an ATX Micro-Fit power supply. The plugs
from the power supply are designed to fit these connectors in only one
orientation. Find the proper orientation and push down firmly until the
connectors completely fit.
• Make sure that your ATX 12V power supply can provide 8A on the +12V
lead and at least 1A on the +5-volt standby lead (+5VSB). The minimum
recommended wattage is 230W, or 300W for a fully configured system.
The system can become unstable and might experience difficulty
powering up if the power supply is inadequate.
• You must install a PSU with a higher power rating if you intend to install
additional devices.
3. USB connectors (9-1 pin FRONT_USB2)
These connectors are for USB 2.0 ports. Connect the USB/GAME module
cable to any of these connectors, then install the module to a slot opening
at the back of the system chassis. These USB connectors comply with USB
2.0 specification that supports up to 480 Mbps connection speed.
Never connect a 1394 cable to the USB connectors. Doing so will damage
the motherboard!

hard disk drives.
Important notes on Serial ATA
• Install the Windows® 2000 Service Pack 4 or the Windows® XP Service
Pack1 before using Serial ATA.
• When using the connectors in Standard IDE mode, connect the primary
(boot) hard disk drive to the SATA1 connector.

6. CPU and System fan connectors (3-pin CPU_FAN1, 3-pin SYS_FAN1)
The fan connectors support cooling fans of 350 mA ~ 740 mA (8.88 W
max.) or a total of 1 A~2.22 A (26.64 W max.) at +12 V. Connect the
fan cables to the fan connectors on the motherboard, making sure that
the black wire of each cable matches the ground pin of the connector.
Do not forget to connect the fan cables to the fan connectors.
Insufficient air flow within the system can damage the motherboard
components. These are not jumpers! DO NOT place jumper caps on the
fan connectors!
