Hardware Setup
This chapter provides you with the information about
hardware setup procedures. While doing the installation,
be careful in holding the components and follow the
installation procedures. For some components, if you
install in the wrong orientation, the components will not
work properly.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the
components.

Hardware Setup
CPU (Central Processing Unit)
The mainboard supports Intel® Core 2 Duo/ Core Duo/ Core Solo/ Celeron M/
Celeron LV 423 BGA (with BGA Passive Cooler) processors in Socket M. When you
are installing the CPU, make sure the CPU has a heat sink and a cooling fan
attached on the top to prevent overheating. If you do not have the heat sink and
cooling fan, contact your dealer to purchase and install them before turning on the
computer.
Important
1. Overheating will seriously damage the CPU and system. Always make
sure the cooling fan can work properly to protect the CPU from overheating.
2. Make sure that you apply an even layer of heat sink paste (or thermal tape)
between the CPU and the heatsink to enhance heat dissipation.
3. While replacing the CPU, always turn off the power supply or unplug the
power supply’s power cord from the grounded outlet first to ensure the
safety of CPU.

CPU & Cooler Set Installation
1. Place the CPU on top of the socket. Make sure to align the gold arrow on the CPU
with the arrow key on the socket.
2. Push the CPU down until its pins securely fit into the socket.
3. On the front end of the CPU socket is a
locking mechanism designed into the
form of a screw. Make sure that you
actuate or deactuate this mechanism
with a screwdriver before and after in-
stalling the CPU.
4. Release the metal clips on the retention
mechanism.
Mainboard photos shown in this sec-
tion are for demonstration only and may
differ from the actual look of your
mainboard.

Hardware Setup
5. Mount the cooler set (fan & heatsink
bundled) on top of the CPU and fit it into
the retention mechanism.
7. Connect the fan power cable from the
mounted fan to the 3-pin fan power con-
nector on the mainboard.
6. Secure the metal clips back to the
retention mechanism.

Installing Memory Modules
1. The memory module has only one notch on the center and will only fit in the right
orientation.
2. Insert the memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the DIMM slot.
Important
You can barely see the golden finger if the memory module is properly inserted
in the DIMM slot.
3. The plastic clip at each side of the DIMM slot will automatically close.

PCI (Peripheral Component Interconnect) Express Slot
PCI Express architecture provides a high performance I/O infrastructure for Desktop
Platforms with transfer rates starting at 2.5 Giga transfers per second over a PCI
Express x1 lane for Gigabit Ethernet, TV Tuners, 1394 controllers, and general pur-
pose I/O. Also, desktop platforms with PCI Express Architecture will be designed to
deliver highest performance in video, graphics, multimedia and other sophisticated
applications. Moreover, PCI Express architecture provides a high performance graphics
infrastructure for Desktop Platforms doubling the capability of existing AGP 8x de-
signs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics
controllers, while PCI Express x1 supports transfer rate of 250 MB/s.
PCI Express x16 Slot
PCI Express x1 Slot
PCI (Peripheral Component Interconnect) Slot
The PCI slot supports LAN cards, SCSI cards, USB cards, and other add-on cards
that comply with PCI specifications. At 32 bits and 33 MHz, it yields a throughput rate
of 133 MBps.

PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines
over which devices can send interrupt signals to the microprocessor. The PCI IRQ

1. The items under each BIOS category described in this chapter are under
continuous update for better system performance. Therefore, the descrip-
tion may be slightly different from the latest BIOS and should be held for
reference only.
2. Upon boot-up, the 1st line appearing after the memory count is the BIOS
version. It is usually in the format:
P9642IMS V1.0 111507 where:
1st digit refers to BIOS maker as A = AMI, W = AWARD, and P =
PHOENIX.
2nd - 5th digit refers to the model number.
6th digit refers to the chipset as I = Intel, N = nVidia, and V = VIA.
7th - 8th digit refers to the customer as MS = all standard customers.
V1.0 refers to the BIOS version.

The sub-menu is used to configure chipset features for optimal system performance.
DRAM Timing Selectable
Selects whether DRAM timing is controlled by the SPD (Serial Presence Detect)
EEPROM on the DRAM module. Setting to [By SPD] enables DRAM timing to be
determined automatically by BIOS based on the configurations on the SPD.
Selecting [Manual] allows users to configure the following fields manually.
CAS Latency Time
This controls the timing delay (in clock cycles) before SDRAM starts a read
command after receiving it. Smaller clocks increase system performance while
bigger clocks provide more stable system performance.
DRAM RAS# to CAS# Delay
This field allows you to set the number of cycles for a timing delay between the
CAS and RAS strobe signals, used when DRAM is written to, read from or
refreshed. Fast speed offers faster performance while slow speed offers
more stable performance.
DRAM RAS# Precharge
This item controls the number of cycles for Row Address Strobe (RAS) to be
allowed to precharge. If insufficient time is allowed for the RAS to accumulate
its charge before DRAM refresh, refresh may be incomplete and DRAM may fail
to retain data. This item applies only when synchronous DRAM is installed in the
system.
Precharge Delay (tRAS)
The field specifies the idle cycles before precharging an idle bank.

This setting allows you to select whether to use the onchip graphics processor
or the PCI Express card.
When set to [Onchip VGA], the motherboard boots up using the onboard graph-
ics processor, even when a PCI Express graphics card is installed.
When set to [PEG Port], the motherboard boots up using the PCI Express graph-
ics card, if one is installed. Otherwise, it defaults to the onboard graphics
processor.
When set to [Auto], the BIOS checks to see if a PCI Express graphics card is
installed. If it detects that a PCI Express graphics card is present, the motherboard
boots up using that card. Otherwise, it defaults to the onboard graphics
processor.
On-Chip Frame Buffer Size
The field specifies the size of system memory allocated for video memory.

ware maintains all system context.
[S3(STR)] The S3 sleep mode is a lower power state where the
information of system configuration and open appli-
cations/files is saved to main memory that remains
powered while most other hardware components turn
off to save energy. The information stored in memory
will be used to restore the system when a “wake up”

CMOS
Checksum of CMOS is incorrect, so the
system loads the default equipment

indicate that CMOS has become corrupt.
This error may have been caused by a
weak battery. Check the battery and

Troubleshooting Action
Reseat the memory, or replace with known good modules.
Fatal error indicating a serious problem with the system. Consult your system
manufacturer. Before declaring the motherboard beyond all hope, eliminate the
possibility of interference by a malfunctioning add-in card. Remove all expansion
cards except the video adapter.
4-7, 9-11
‧ If beep codes are generated when all other expansion cards are absent, consult
your system manufacturer’s technical support.
‧ If beep codes are not generated when all other expansion cards are absent, one
of the add-in cards is causing the malfunction. Insert the cards back into the
system one at a time until the problem happens again. This will reveal the
malfunctioning card.
8
If the system video adapter is an add-in card, replace or reseat the video adapter.
If the video adapter is an integrated part of the system board, the board may be
faulty.
