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.
