2.4. CPU, Memory and Expansion Slots

2.4.1. Installation of the CPU

To install your processor, please complete the following set of instructions

1. Locate a small dot marked on the top of the CPU. This mark indicates

Pin 1 of the CPU.

2. Locate Pin 1 for the Socket on the mainboard.

3.

There is a lever on the side of the socket. First push this lever sideways and then lift it to a 90-degree angle.

4.

Insert the CPU into the Socket. Please make sure that Pin 1 for the CPU is inserted into Pin 1 of the Socket.

5. When the CPU is installed correctly push the lever back into place.

6. Install a proper heat sink with cooling fan for proper heat dissipation. Failing to install a heat sink with cooling fan may cause overheating which will burnout your CPU and damage your mainboard. The heat sink with cooling fan should be installed on the retention mechanism that is provided. This retention mechanism is designed to hold the bigger Heat Sink that is required for the Pentium 4 CPU.

Heat Sink and Retention Mechanism

You must use an Intel approved Heat Sink. This CPU operates at a very high frequency and therefore heats up very quickly. (A normal heat sink will not be adequate to cool the CPU and the CPU will burn-out.) These heat sinks are very heavy. A retention mechanism for the Heat Sink has been provided with the mainboard.

2.4.2. Memory Modules

These mainboards all have three 184-pin DDR SDRAM slots. If registered DDR

SDRAM modules are used then they can support a maximum of 3 GB DRAM. If unbuffered DDR SDRAM modules are used they can support a maximum of 1.5

GB DRAM

The DDR SDRAM slots are located on the right hand side of the board. To install the DIMM’s into these slots, make sure the white lever at each side of the slot has been pulled down to an angle of approximately 45°. Make sure that the

DIMM is in the correct orientation. Place the DIMM on the slot and push down firmly.The white levers will come back up and lock the module in place.

Top View of a 184-pin DIMM Slot

40 pins

Page 14

52 pins



Important: The DIMM’s can only be fitted into the slots in one orientation. Make sure that the DIMM’s are in the correct orientation and the pins are correctly aligned before you insert them.

NOTE: “Out Of Memory” Error Message

If you have installed more than 512 MB of RAM and are running Microsoft Windows Millennium Edition, Windows 98 Second Edition, Windows 98 or Windows 95 you may experience memory problems. Two symptoms of these problems are being unable to run an MS-DOS session while you are running Windows or the computer may stop responding while Windows is starting.

There are three possible solutions to this problem:

1) Reduce the amount of memory Vcache uses to 512 MB or less by altering the MaxFileCache setting in the System.ini file.

2) Use the System Configuration Utility to reduce the amount of memory Windows uses to 512 MB or less.

3) Reduce the memory installed on your computer to 512 MB or less.

This problem can also occur if you are using an Advanced Graphic Port (AGP) video adapter.

2.4.3. PCI Slots

These boards come with six PCI slots. They are located on the left hand side of the board. Both PCI and PCI expansion cards may require IRQ’s. This mainboard complies with Plug and Play (PnP) specifications. Whenever a PnP compliant card is added the system will automatically be configured and the IRQ’s will be assigned automatically.

When you are inserting your PCI card make sure that the pins are correctly aligned. When the pins are properly aligned with the hole’s in the slot, push down gently.

Managing the PC BIOS

3.1. Award BIOS CMOS Setup Utility

Once you have installed the mainboard you still need to setup the BIOS before you can run your PC. The EEPROM on the mainboard stores the AWARD BIOS

CMOS Setup Utility, which allows you to configure your system. When you want to configure or make any changes to the configuration of your system BIOS you must run the BIOS CMOS Setup Utility.

GETTING STARTED

Every time you start your computer, the system provides you with an opportunity to run the BIOS CMOS Setup Utility. As soon as you turn on your system, press the <Delete> button to activate the BIOS CMOS Setup Utility.

If your computer finishes the POST (Power-On-Self-Test) the BIOS CMOS Setup

Utility will not be activated. If your computer completes the POST you need to restart the system to activate the BIOS CMOS Setup Utility. To restart the system, you can either turn the power off, press the reset button on your chassis or press the <Ctrl> + <Alt> + <Delete> button. In all three cases the system will restart and, to activate the BIOS CMOS Setup Utility, you must immediately press the <Delete> button.

3.4. Advanced BIOS Settings


Virus Warning

When you enable the virus warning you will receive a warning message whenever a program (specifically, a virus) attempts to write to the boot sector or the partition table of the hard disk drive. If you receive such a message you should immediately run an anti-virus program. Keep in mind that this feature

only protects the boot sector and not the entire hard drive.

NOTE! Many disk diagnostic programs that access the boot sector table can trigger the virus-warning message. If you plan to run such a program, we recommend that you first disable the virus warning.

CPU L1 & L2 Cache

This BIOS setting can be used to enable or disable the CPU's L1 (primary) and L2

(secondary) cache.

CPU L2 Cache ECC Checking

When you select Enabled, the ECC checking will ensure that the data stored on the L2 cache is accurate.

This field is effective only in systems with two floppy drives. When Enabled is selected physical drive B is assigned to logical drive A, and physical drive A is assigned to logical drive B.


Page 29


Boot Up Floppy Seek

When enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720

KB, 1.2 MB, and 1.44 MB capacity all have 80 tracks. Very few modern PCs have

40-track floppy drives so we therefore recommend that you set this field to

Disabled to save time.

Boot Up NumLock Status

This controls the state of the NumLock key when the system boots. This field is toggled between On or Off. When it is on the numeric keypad generates numbers instead of controlling the cursor operations. When it is off the numeric keypad controls cursor operations and does not generate numbers.

Typematic Rate Setting

The keyboard controller determines the rate at which the keystrokes from the keyboard are repeated. If you enable this option then the typematic rate and the typematic delay can be selected.

Typematic Rate

This is the rate a character will repeat itself on the screen when you hold down a key.

Typematic Delay

This is the delay time (Msec) before the repetition of characters starts.

Security Option

This field allows you to select the “Setup” or “System” security option. It works concurrently with the “ Set Supervisor Password” in the main menu.

When the "Setup" option is selected, you will be prompted to enter your

"Password" before you can start the BIOS CMOS Setup Utility. When you select

"System" option, you will be prompted to enter your password in order to load the Operating System.

TIP: Forgot your password then clear the RTC RAM

If you happen to forget your password you can use Jumper 13 (JP13) to clear the password by erasing the CMOS Real Time Clock (RTC) Ram. For further details on how to do this please see section 2.9.4 on page 24. (Click Here)

PS/2 Mouse Function Control

If you have installed a serial pointing device and your system has a PS/2 mouse port you should disable this option.

DDR). If you select By SPD the BIOS will automatically detect the actual

DRAM Clock.

!DRAM Timing

This field determines the DRAM read/write timing. The performance parameters of the memory chips (DRAM) you have installed will determine the value in this field. Do not change the value from the factory setting unless you install new memory that has a different performance rating than the original

DRAMs.

!SDRAM Cycle Length

Before SDRAM can execute a read command that it receives, there is a delay time, which is measured in clock cycles (CLK). The lower the delay time the faster the execution of commands will be. It is therefore desirable to minimize this cycle length. Some memory modules are unable to deal with short delay times. We recommend that you set this delay time between 2.5 and 3

CLK’s (the default is 2.5). If your system becomes unstable we recommend that you increase the delay time.

This selection will cause the system to turn off the vertical and horizontal synchronization ports and write blanks to the video buffer.

This option only writes blanks to the video buffer.

Select this option if your monitor supports the Display Power Management Signaling (DPMS) standard of the Video Electronics Standards to select video power management values.

MODEM Use IRQ

This determines the IRQ which the MODEM can use for power saving purposes.

This mainboard has the ACPI feature designed on the board and it will “wakeup” automatically when it detects an incoming modem Ring-in signal. Before you can use the Ring-in signal to wakeup your PC system, you have to install the

“External” modem to your PC system and tell the PC system which serial port connects to the modem by selecting the IRQ in this field, (officially, COM 1 uses

IRQ4, and COM 2 uses IRQ3).

Soft-Off by PWRBTN

Pressing the power button for more than 4 seconds forces the system to enter the Soft-Off state when the system has “hung”.

!Date (of Month)/Resume Time (hh:mm:ss)

When RTC Alarm Resume is enabled, your can set the date and time at which the RTC (real-time clock) alarm awakens the system from Suspend mode.

!IRQs Activity Monitoring

The following is a list of IRQ’s, Interrupt ReQuests, which can be exempted much as the COM ports and LPT ports above can. When an I/O device wants to gain the attention of the operating system, it signals this by causing an

IRQ to occur. When the operating system is ready to respond to the request, it interrupts itself and performs the service.

CPU Clock Ratio

This field allows you to select the clock ratio. Most CPU clock ratios are fixed inside the CPU by the manufacturers that prohibit you to make any changes. In this case, the setting in this field will make no change to the CPU clock ratio since it locks and is automatically determined by the CPU.

Auto Detect DIMM/PCI Clk

When “Enabled” is selected, the mainboard will detect the presence of devices on

DIMM and PCI slots. When there is no device present on some of the PCI or

DIMM connectors, the clock on the related DIMM and PCI slot will be disabled to reduce the Electro-Magnetic Interference (EMI).

Spread Spectrum

When Spread Spectrum is enabled, the EMI radiation on this mainboard will be reduced.

CPU Clock

You can use this field to adjust the front side system bus clock speed of the CPU.

The clock frequency can be incremented by +/- 1MHz. This allows you to fintune the system performance of your PC.
