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.

ONLY FOR SERVICE PERSONEL

Always unplug the power cord before
inserting any add-on card or module.

Hardware Setup

CPU (Central Processing Unit)

The mainboard supports Intel® Yonah (Intel® Core™ Duo/ T2000 Seqence) and
Merom Napa Reflash (Intel® Core™ 2 Duo/ T5000 & T7000 Sequence) in PGA
Package. 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.

2-3

MS-7265 Mainboard

CPU & Cooler Installation for PGA Package

1. Locate the CPU socket on the
mainboard.

2. 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.

3. Push the CPU down until its pins securely fit into the socket.

4. On the front end of the CPU socket is
a locking mechanism designed into
the form of a screw head. Make sure
that you actuate or deactuate this
mechanism with a screwdriver be­fore and after installing the CPU.

2-4

Hardware Setup

5. Flip over the mainboard and locate the position of the CPU socket.

6. Detach the shield of the CPU cooler backplate paste and install the backplate
to the back of the CPU socket with holes aligned.

7. The heatsink paste helps to enhance heat dissipation of the CPU. Before

installing the cooler set (fan & heatsink bundled), make sure that you detach
the shield of the heatsink paste under the cooler set.

8. Locate the four screw holes around the CPU socket where the CPU cooler

backplate was installed. Align the cooler set with the screw holes and mount
it on top of the CPU.

9. Screw to secure the cooler set to the mainboard.

10. Connect the fan power cable to the CPUFAN1 connector on the mainboard.

Memory

These DIMM slots are used for installing memory modules.

DDR2

240-pin, 1.8V

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) Slot

The PCI slot supports LAN card, SCSI card, USB card, and other add-on cards
that comply with PCI specifications.

32-bit PCI Slot

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 pins are typically connected to the PCI bus pins as follows:

Order 1 Order 2 Order 3 Order 4

32-bit PCI1 INT A# INT B# INT C# INT D#

Important

When adding or removing expansion cards, make sure that you
unplug the power supply first. Meanwhile, read the documentation
for the expansion card to configure any necessary hardware or
software settings for the expansion card, such as jumpers,
switches or BIOS configuration.

ACPI Suspend Type

This item specifies the power saving modes for ACPI function. If your operat­ing system supports ACPI, such as Windows 98SE, Windows ME, Windows
2000 and Windows XP, you can choose to enter the Standby mode in S1 (POS)
or S3 (STR) fashion through the setting of this field. Options are:

[S1/POS] The S1 sleep mode is a low power state. In this state, no

[S3/STR] The S3 sleep mode is a lower power state where the infor

system context is lost (CPU or chipset) and hardware main
tains all system context.

mation of system configuration and open applications/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” event occurs.

MS-7265 Mainboard

Soft-Off by PWR-BTTN

When [Enabled], turning the system off with the on/off button places the sys­tem in a very low-power-usage state, with only enough circuitry receiving
power to detect power button activity or Resume by Ring activity.

Wake-Up By PCI card

When setting to [Enabled], this setting allows your system to be awakened
from the power saving modes through any event on PCI PME (Power Manage­ment Event).

USB KB WakeUp From S3 (S4)

When setting to [Enabled], this setting allows your system to be awakened
from S3 state.

Resume by Alarm

When [Enabled], your can set the date and time at which the RTC (real-time
clock) alarm awakens the system from suspend mode.

POWER ON Function

This controls how the PS/2 mouse or keyboard can power on the system.

PWRON After PWR-fail

This item specifies whether your system will reboot after a power failure or
interrupt occurs. Available settings are:

Frequency/ Voltage Control

Auto Detect PCI Clk

This item is used to auto detect the PCI slots. When set to [Enabled], the system
will remove (turn off) clocks from empty PCI slots to minimize the electromag­netic interference (EMI).

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec­trum function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves.

Important

1. If you do not have any EMI problem, leave the setting at [Disabled]
for optimal system stability and performance. But if you are plagued
by EMI, select the value of Spread Spectrum for EMI reduction.

2. The greater the Spread Spectrum value is, the greater the EMI is
reduced, and the system will become less stable. For the most
suitable Spread Spectrum value, please consult your local EMI
regulation.

3. Remember to disable Spread Spectrum if you are overclocking
because even a slight jitter can introduce a temporary boost in
clock speed which may just cause your overclocked processor to
lock up.

optimal performance of the mainboard. The Fail-Safe Defaults are the default
values set by the BIOS vendor for stable system performance.

When you select Load Fail-Safe Defaults, a message as below appears:

When you select Load Optimized Defaults, a message as below appears:

Type the password, up to six characters in length, and press <Enter>. The
password typed now will replace any previously set password from CMOS
memory. You will be prompted to confirm the password. Retype the password
and press <Enter>. You may also press <Esc> to abort the selection and not
enter a password.

To clear a set password, just press <Enter> when you are prompted to enter
the password. A message will show up confirming the password will be
disabled. Once the password is disabled, the system will boot and you can
enter Setup without entering any password.

When a password has been set, you will be prompted to enter it every time you
try to enter Setup. This prevents an unauthorized person from changing any
part of your system configuration.
