Hardware Setup
CPU (Central Processing Unit)
This mainboard supports Intel® CoreTM2 Quad, CoreTM2 Duo, Pentium® and Celeron®
processors in the LGA775 package. When you are installing the CPU, make sure to
install the cooler to prevent overheating. If you do not have the CPU cooler, consult
your dealer before turning on the computer.
Important
Overheating
Overheating will seriously damage the CPU and system. Always make sure
the cooling fan can work properly to protect the CPU from overheating. Make
sure that you apply an even layer of thermal paste (or thermal tape) between
the CPU and the heatsink to enhance heat dissipation.
Replaceing the CPU
While replacing the CPU, always turn off the ATX power supply or unplug the
power supply’s power cord from the grounded outlet first to ensure the safety
of CPU.

CPU & Cooler Installation
When you are installing the CPU, make sure the CPU has a cooler attached on
the top to prevent overheating. Meanwhile, do not forget to apply some thermal
paste on CPU before installing the heat sink/cooler fan for better heat dispersion.
Follow the steps below to install the CPU & cooler correctly. Wrong installation will
cause the damage of your CPU & mainboard.
1. The CPU socket has a plastic cap
on it to protect the contact from
damage. Before you install the CPU,
always cover it to protect the socket
pin.
2. Remove the cap from lever hinge
side (as the arrow shows).
3. The pins of socket reveal.
4. Open the load lever.
Important
1. Confirm if your CPU cooler is firmly installed before turning on your
system.
2. Do not touch the CPU socket pins to avoid damaging.
3. The availability of the CPU land side cover depends on your CPU packing.

ACPI Standby State
This item specifies the power saving modes for ACPI function. If your operating
system supports ACPI, such as Windows 2000/ XP , you can choose to enter the
Standby mode in S1 or S3 fashion through the setting of this field. Settings are:
[S1]
The S1 sleep mode is a low power state. In this state, no system
context is lost (CPU or chipset) and hardware maintains all sys
tem context.
[S3]
The S3 sleep mode is a lower power state where the in formation
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.

IRQ 3/ 4/ 5/ 7/ 9/ 10/ 11/ 14/ 15
These items specify the bus where the specified IRQ line is used. The settings
determine if AMI BIOS should remove an IRQ from the pool of available IRQs
passed to devices that are configurable by the system BIOS. The available IRQ
pool is determined by reading the ESCD NVRAM. If more IRQs must be removed
from the IRQ pool, the end user can use these settings to reserve the IRQ by
assigning an [Reserved] setting to it. Onboard I/O is configured by AMI BIOS. All
IRQs used by onboard I/O are configured as [Available]. If all IRQs are set to
[Reserved], and IRQ 14/15 are allocated to the onboard PCI IDE, IRQ 9 will still
be available for PCI and PnP devices.
Important
IRQ (Interrupt Request) lines are system resources allocated to I/O devices.
When an I/O device needs to gain attention of the operating system, it
signals this by causing an IRQ to occur. After receiving the signal, when the
operating system is ready, the system will interrupt itself and perform the
service required by the I/O device.
