Cooling Solutions
As processor technology pushes to faster speeds and higher performance, thermal management becomes increasingly crucial when building computer systems. Maintaining the proper thermal environment is key to reliable, long-term system operation. The overall goal in providing the proper thermal environment is keeping the processor below its specified maximum case temperature. Heatsinks induce improved processor heat dissipation through increased surface area and concentrated airflow from attached fans. In addition, interface materials allow effective transfers of heat from the processor to the heatsink. For optimum heat transfer, Intel recommends the use of thermal grease and mounting clips to attach the heatsink to the processor. When selecting a thermal solution for your system, please refer to the website below for collection of heatsinks evaluated and recommended by Intel for use with Intel processors. Note, those heatsinks are recommended for maintaining the specified Maximum T case requirement. In addition, this collection is not intended to be a comprehensive listing of all heatsinks that support Intel processors.

2-3-2 About Intel Pentium 4 478-pin CPU
This motherboard provides a 478-pin surface mount, Zero Insertion Force (ZIF) socket, referred to as the mPGA478B socket supports Intel Pentium 4 processor in the 478 Pin package utilizes Flip-Chip Pin Grid Array (FC-PGA2) package technology.
The CPU that comes with the motherboard should have a cooling FAN attached to prevent overheating. If this is not the case, then purchase a correct cooling FAN before you turn on your system.
WARNING!
Be sure that there is sufficient air circulation across the processor’s heatsink and CPU cooling FAN is working correctly, otherwise it may cause the processor and motherboard overheat and damage, you may install an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and open it by first pulling the level sideways away from the socket then upward to a 90-degree angle. Insert the CPU with the correct orientation as shown below. The notched corner should point toward the end of the level. Because the CPU has a corner pin for two of the four corners, the CPU will only fit in the orientation as shown.
CPU ZIF mPGAB Socket
Colden Arrow
mPGA478B
When you put the CPU into the ZIF socket. No force require to insert of the CPU, then press the level to Locate position slightly without any extra force.
2-4 Install Memory
This motherboard provides two 184-pin DUAL INLINE MEMORY MODULES (DIMM) sites for memory expansion available from minimum memory size of 64MB to maximum memory size of 2.0GB DDR (Double Data Rate) SDRAM.

Total System Memory (Max. 2.0GB) 2 64MB∼2.0GB
NOTE!
Make sure the installed memory are DDR266 SDRAM support 133MHz memory clock, otherwise the system may hang during startup.
Generally, installing DDR SDRAM modules to your motherboard is very easy, you can refer to figure 2-4 to see what a 184-Pin DDR200/DDR266 SDRAM module looks like.
DDR2 (BANK2+ BANK3)
DDR1 (BANK0+ BANK1)
NOTE!
When you install DIMM module fully into the DIMM socket the eject tab should be locked into the DIMM module very firmly and fit into its indention on both sides.
WARNING!
For the DDR SDRAM CLOCK is set at 133MHz, use only DDR266­compliant DDR Modules. When this motherboard operate at 133Mhz, most system will not even boot if non-compliant modules are used because of the strict timing issues, if your DDR Modules are not DDR266-compliant, set the DDR SDRAM clock to 100MHz to ensure system stability.
2-5 Expansion Cards
WARNING!
Turn off your power when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards.
Figure 2-4
11
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation for your expansion card and make any necessary hardware or software setting for your expansion card such as jumpers.
2. Remove your computer’s cover and the bracket plate on the slot you intend to use.
3. Align the card’s connectors and press firmly.
4. Secure the card on the slot with the screen you remove above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively assign to one use. In a standard design, there are 16 IRQs available but most of them are already in use.
Standard Interrupt Assignments
IRQ Priority Standard function
0 N/A System Timer 1 N/A Keyboard Controller 2 N/A Programmable Interrupt 3 * 8 Communications Port (COM2) 4 * 9 Communications Port (COM1) 5 * 6 Sound Card (sometimes LPT2) 6 * 11 Floppy Disk Controller 7 * 7 Printer Port (LPT1) 8 N/A System CMOS/Real Time Clock
9 * 10 ACPI Mode when enabled 10 * 3 IRQ Holder for PCI Steering 11 * 2 IRQ Holder for PCI Steering 12 * 4 PS/2 Compatible Mouse Port 13 N/A Numeric Data Processor 14 * 5 Primary IDE Channel 15 * 1 Secondary IDE Channel
* These IRQs are usually available for ISA or PCI devices.

IMPORTANT!
If using PCI cards on shared slots, make sure that the drivers support “S hared IRQ” or that the cards don’t need IRQ assignments. C onflicts will arise between the two PCI groups that will make the system unstable or cards inoperable.
2-5-4 AGP Slot
This motherboard provides an AGP Slot, only support the 1.5V 4X AGP VGA card. Do not use AGP 2X card (3.3V) in this motherboard. It will burn and damage the
motherboard due to Intel® 845 chipset can not support AGP 2X (3.3V)
IMPORTANT!
Before you plug-in AGP card, please make sure the following notice is fully understood and practiced. If your AGP card has “AGP 4X notch (show below) please make sure your AGP card is AGP 4X (1.5V) not AGP 2X (3.3V)
AGP SLOT
Example 1:
SiS 305 & ATi Rage 128 Pro AGP card those golden finger is compatible
with 2X/4X mode AGP slot, but only can support 2X (3.3V) only. If you install these cards in Intel® 845 based motherboard it will burn and damage the motherboard.
Example 2:
We also find Diamond Vipper V770 golden finger is design for 2X/4X mode
AGP Slot. It can be adjusted the jumper for AGP 2X (3.3V) or AGP 4X (1.5V). But the factory default setting is 2X (3.3V). If you install this AGP card in motherboard without change the jumper setting to 4X (1.5V), it will burn the motherboard.

(1) Power Connector (20-pin block) : ATXPWR
ATX Power Supply connector. This is a new defined 20-pins connector that usually
comes with ATX case. The ATX Power Supply allows to use soft power on momentary switch that connect from the front panel switch to 2-pins Power On jumper pole on the motherboard. When the power switch on the back of the ATX power supply turned on, the full power will not come into the system board until the front panel switch is momentarily pressed. Press this switch again will turn off the power to the system board.
