Thermal 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.

Introduction of 694CS/VM4 Motherboard
1-1 Feature of motherboard
The 694CS/VM4 motherboard is design for use Intel PentiumIII /Celeron PPGA/FC-
PGA CPU, which utilize the Socket 370 design and the memory size expandable to
1.0GB.
This motherboard use the newest VIA Apollo Pro VT82C694X chipset, whose
133MHz front side bus & 133MHz memory interface delivers a clear upgrade path to
the future generation of 133MHz processors and PC-133 SDRAM. The 694CS
motherboard offers ULTRA DMA 100 (ATA 100) and VM4 motherboard offers
ULTRA DMA 66 (ATA 66) to provide speedier HDD throughout that boosts overall
system performance. Its on board integrated AC’97 2.1 CODEC which is fully
compatible with Sound Blaster Prothat gives you the best sound quality and
compatibility.
The special function of Auto Setting and Jump-less solution, allows user to install
CPU without change any jumper. User can also setting Front Side Bus Frequency
(CPU Host Clock), CPU ratio in BIOS SETUP “Miscellaneous Control” for over-
clocking possibility.
With 2 USB control as well as capability of expanding to 4 USB connectors, the
694CS meet future USB demand also this motherboard includes built-in hardware
monitor function that capable of monitor and protect your computer.
The 694CS/VM4 motherboard supports ACPI function such like Ring_In Wake Up,
Ring_In Power On, Wake On LAN, Wake On Modem, RTC Power On for OS
Directed Power Management.
The Special function in BIOS SETUP can choose system clock step by step between
6699Mhz, 100132Mhz, 133166Mhz to approach Over-Clock possibility. This
board also provides system auto detection and rebooting function that uses default
frequency when system boot fail by over-clocking.
This motherboard supports standard Synchronous DRAM (SDRAM) and Virtual
Channel Memory SDRAM (VCM SDRAM), in a flexible mix/match manner.
This motherboard provides high performance & meets future specification demand. It
is really wise choice for your computer.

LAN (interface) - Local Area Network - the interface to your local area network.
BIOS (Basic Input/Output System) - the program logic used to boot up a computer
and establish the relationship between the various components.
Driver - software, which defines the characteristics of a device for use by another
device or other software.
Processor - the "central processing unit" (CPU); the principal integrated circuit used
for doing the "computing" in "personal computer"
Front Side Bus Frequency
The working frequency of the motherboard, which is generated by the clock generator
for CPU, DRAM and PCI BUS.
CPU L2 Cache
The flash memory inside the CPU, normally Pentium III CPU has 256K or above,
while Celeron CPU will have 128K.

2-3-2 Install CPU
This motherboard Provides a ZIF Socket 370. 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.

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.
2-3-3 Over clock Running
WARNING! This section is for experienced motherboard installer only. Over clocking
can result in system instability or even shortening life of the processor.
After setting the Jumper JK1, JK2, BSEL0, BSEL1 you can choose over clock running by
BIOS CMOS SETUP UTILITY. When you entered CMOS SETUP UTILITY, choose
“Miscellaneous Control” you will see the screen as below then.

2-4 Install Memory
This motherboard provides two 168-pin DUAL INLINE MEMORY MODULES
(DIMM) sites for memory expansion available from minimum memory size of 32MB
to maximum memory size of 1.0GB SDRAM.
Valid Memory Configurations
Bank 168-Pin DIMM Total Memory
Bank 0, 1 (DIMM1) SDRAM 32, 64, 128, 256, 512MB X1 32MB512MB
Bank 2, 3 (DIMM2) SDRAM 32, 64, 128, 256, 512MB X1 32MB512MB
Total System Memory (Max. 1.0GB) 32MB1.0GB
NOTE! Make sure the total installed memory does not exceeds 1.0GB, otherwise
the system may hang during startup.
Generally, installing SDRAM modules to your motherboard is very easy, you can
refer to figure 2-4 to see what a 168-Pin PC100 & PC133 SDRAM module looks like.

13
DIMM2 (BANK2+ BANK3)
DIMM1
(
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 SDRAM CLOCK is set at 133MHz, use only PC133-compliant
DIMMs. 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 DIMM are not PC133-compliant, set the 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.
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
Figure 2-4

14
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
