CPU (Central Processing Unit)

The mainboard supports Intel^®Penryn/Core 2 Duo/Core Duo/Celeron M proces-

sors in Socket P. 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.

* The CF1 slot and the IDE1 connector shares and uses the same channel. CF1

and IDE1 can support up to 2 IDE devices without CF device or 1 IDE device

with 1 CF device.

* If you install two IDE devices, you must configure the second drive to Slave

mode by setting its jumper. Refer to the hard disk documentation supplied by

hard disk vendors for jumper setting instructions.

* If you install one IDE device with ATA133 IDE cable and one CF device, you

must configure the CF drive to Master mode by setting jumper JCF_SEL1.

CF only supports Master mode by using ATA133 IDE cable. CF only supports

Slave mode by using ATA33 IDE cable.

BIOS Setup

Hardware Prefetcher

The processor has a hardware prefetcher that automatically analyzes its re-

quirements and prefetches data and instructions from the memory into the

Level 2 cache that are likely to be required in the near future. This reduces the

latency associated with memory reads. When enabled, the processor's hard-

ware prefetcher will be enabled and allowed to automatically prefetch data and

code for the processor. When disabled, the processor's hardware prefetcher

will be disabled.

Adjacent Cache Line Prefetch

The processor has a hardware adjacent cache line prefetch mechanism that

automatically fetches an extra 64-byte cache line whenever the processor

requests for a 64-byte cache line. This reduces cache latency by making the

next cache line immediately available if the processor requires it as well. When

enabled, the processor will retrieve the currently requested cache line, as well

as the subsequent cache line. When disabled, the processor will only retrieve

the currently requested cache line.

Max CPUID Value Limit

The Max CPUID Value Limit BIOS feature allows you to circumvent problems

with older operating systems that do not support the Intel Pentium 4 processor

with Hyper-Threading Technology. When enabled, the processor will limit the

maximum CPUID input value to 03h when queried, even if the processor sup-

ports a higher CPUID input value. When disabled, the processor will return the

actual maximum CPUID input value of the processor when queried.

Intel(R) Virtualization Tech

Virtualization enhanced by Intel Virtualization Technology will allow a platform

to run multiple operating systems and applications in independent partitions.

With virtualization, one computer system can function as multiple “virtual” systems.

Execute Disable Bit Capability

Intel's Execute Disable Bit functionality can prevent certain classes of malicious

"buffer overflow" attacks when combined with a supporting operating system.

This functionality allows the processor to classify areas in memory by where

application code can execute and where it cannot. When a malicious worm

attempts to insert code in the buffer, the processor disables code execution,

preventing damage or worm propagation.

Core Multi-Processing

CMP (Core Multi Processing) is the ability to have many independent processing

cores on a single die, each with their own L1 Code & Data caches, Local APICs

& thermal controls, while having a shared L2 cache, power management & bus

interface. Intel multi-core architecture has a single Intel processor package that

contains two or more processor "execution cores," or computational engines to

enable enhanced performance and more-efficient simultaneous processing of

multiple tasks.

Quick Boot

Enabling this setting will cause the BIOS power-on self test routine to skip some

of its tests during bootup for faster system boot.

Quiet Boot

This BIOS feature determines if the BIOS should hide the normal POST mes-

sages with the motherboard or system manufacturer's full-screen logo.

When it is enabled, the BIOS will display the full-screen logo during the boot-up

sequence, hiding normal POST messages.

When it is disabled, the BIOS will display the normal POST messages, instead of

the full-screen logo.

Please note that enabling this BIOS feature often adds 2-3 seconds of delay to

the booting sequence. This delay ensures that the logo is displayed for a

sufficient amount of time. Therefore, it is recommended that you disable this

BIOS feature for a faster boot-up time.

AddOn ROM Display Mode

This item is used to determine the display mode when an optional ROM is

initialized during POST. When set to [Force BIOS], the display mode used by AMI

BIOS is used. Select [Keep Current] if you want to use the display mode of

optionalROM.

Bootup Num-Lock

This setting is to set the Num Lock status when the system is powered on.

Setting to [On] will turn on the Num Lock key when the system is powered on.

Setting to [Off] will allow users to use the arrow keys on the numeric keypad.

PS/2 Mouse Support

Select [Enabled] if you need to use a PS/2-interfaced mouse in the operating

system.

Wait For ‘F1’ If Error

When this setting is set to [Enabled] and the boot sequence encounters an

error, it asks you to press F1. If disabled, the system continues to boot without

waiting for you to press any keys.

Hit ‘DEL’ Message Display

Set this option to [Disabled] to prevent the message as follows:

Hit Del if you want to run setup

It will prevent the message from appearing on the first BIOS screen when the

computer boots. Set it to [Enabled] when you want to run the BIOS Setup Utility.

Interrupt 19 Capture

Interrupt 19 is the software interrupt that handles the boot disk function. When

enabled, this BIOS feature allows the ROM BIOS of these host adaptors to

"capture" Interrupt 19 during the boot process so that drives attached to these

adaptors can function as bootable disks. In addition, it allows you to gain ac-

3-20

BIOS Setup

cess to the host adaptor's ROM setup utility, if one is available.

When disabled, the ROM BIOS of these host adaptors will not be able to "cap-

ture" Interrupt 19. Therefore, you will not be able to boot operating systems

from any bootable disks attached to these host adaptors. Nor will you be able to

gain access to their ROM setup utilities.

Internal Graphics Mode Select

The field specifies the size of system memory allocated for video memory.

PEG Port

This setting allows you to select whether to use the onchip graphics processor

or the PCI Express card. 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.

PEG Force X1

This BIOS feature allows you to convert a PCI Express X16 slot into a PCI

Express X1 slot. When [Enabled], the PCI Express X16 slot will be forced to run

in the PCI Express X1 mode. When [Disabled], the PCI Express X16 slot will be

allowed to run in its normal PCI Express X16 mode.

If you have a PCI Express X16 graphics card installed in your system, you

should disable this BIOS feature. This allows for optimal performance of the

card by ensuring maximum transfer rates between the graphics card and the

motherboard.

But if you need to install a PCI Express X1 card into the PCI Express X16 slot,

you should enable this BIOS feature to ensure maximum compatibility.
