As processor technology pushes to faster speeds and higher perfor ance, ther al
anage ent beco es increasingly crucial when building co puter syste s. Maintaining the
proper ther al environ ent is key to reliable, long-ter syste operation. The overall goal in
providing the proper ther al environ ent is keeping the processor below its specified
axi u case te perature. Heatsinks induce i proved processor heat dissipation through
increased surface area and concentrated airflow fro attached fans. In addition, interface
aterials allow effective transfers of heat fro the processor to the heatsink. For opti u
heat transfer, Intel reco ends the use of ther al grease and ounting clips to attach the
heatsink to the processor.
When selecting a ther al solution for your syste , please refer to the website below for
collection of heatsinks evaluated and reco ended by Intel for use with Intel processors.

Introduction of 694AS Motherboard
1-1 Feature of motherboard
The 694AS otherboard is design for use Intel Pentiu III /Celeron PPGA/FC-PGA CPU,
which utilize the Socket 370 design and the e ory size expandable to 1.5GB.
This otherboard use the newest VIA Apollo Pro VT82C694X chipset, whose 133MHz front
side bus & 133MHz e ory interface delivers a clear upgrade path to the future generation of
133MHz processors and PC-133 SDRAM. The 694AS otherboard offers ULTRA ATA 100
to provide speedier HDD throughout that boosts overall syste perfor ance.
The 694AS also has an integrated AC’97 2.1 CODEC on board which is fully co patible with
Sound Blaster Pro

that gives you the best sound quality and co patibility.
With 2 USB control as well as capability of expanding to 4 USB connectors, the 694AS eet
future USB de and also this otherboard includes built-in hardware onitor function that
capable of onitor and protect your co puter.
The 694AS otherboard supports ACPI function such like Ring_In Wake Up, Ring_In Power
On, Wake On LAN, Wake On Mode , RTC Power On for OS Directed Power Manage ent.
The Special fuction in BIOS SETUP can choose syste ’s CPU core voltage, and syste clock
step by step between 66∼99Mhz, 100∼132Mhz, 133∼166Mhz to approach Over-Clock
possiblilty. This board also provides syste auto detection and rebooting function that uses
default frequency when syste boot fail by over-clocking.
This otherboard supports standard Synchronous DRAM (SDRAM) and Virtual Channel
Me ory SDRAM (VCM SDRAM), in a flexible ix/ atch anner.

BIOS (Basic Input/Output Syste ) - the progra logic used to boot up a co puter and
establish the relationship between the various co ponents.
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 "co puting" in "personal co puter"
Front Side Bus Frequency
The working frequency of the otherboard, which is generated by the clock generator for
CPU, DRAM and PCI BUS.
CPU L2 Cache
The flash e ory inside the CPU, nor ally Pentiu III CPU has 256K or above, while
Celeron CPU will have 128K.

2-3-2 Install CPU
This otherboard Provides a ZIF Socket 370. The CPU that co es with the otherboard
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 syste .
WARNING! Be sure that there is sufficient air circulation across the processor’s
heatsink and CPU cooling FAN is working correctly, otherwise it ay
cause the processor and otherboard overheat and da age, you ay install
an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your syste and re ove its cover. Locate the ZIF socket and
open it by first pulling the level sideways away fro 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.

2-3-3 Over clock Running
WARNING! This section is for experienced otherboard installer only. Over clocking
can result in syste unstability or even shortening life of the processor.
After setting the Ju per JCK1, JCK2 you can choose overclock 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 otherboard provides three 168-pin DUAL INLINE MEMORY MODULES (DIMM)
sites for e ory expansion available fro ini u e ory size of 32MB to axi u
e ory size of 1.5GB SDRAM.
Valid Memory Configurations
Bank 168-Pin DIMM Total Memory
Bank 0, 1 (DIMM1) SDRAM 32, 64, 128, 256, 512MB X1 32MB∼512MB

NOTE! Make sure the total installed e ory does not exceeds 1.5GB, otherwise the
syste ay hang during startup.

Generally, installing SDRAM odules to your otherboard is very easy, you can refer to
figure 2-4 to see what a 168-Pin PC100 & PC133 SDRAM odule looks like.

NOTE! When you install DIMM odule fully into the DIMM socket the eject tab should be
locked into the DIMM odule very fi ly and fit into its indention on both sides.
WARNING! For the SDRAM CLOCK is set at 133MHz, use only PC133-co pliant DIMMs.
When this otherboard operate at 133Mhz, ost syste will not even boot if
non-co pliant odules are used because of the strick ti ing issues, if your
DIMM are not PC133-co pliant, set the SDRAM clock to 100MHz to ensure
syste stability.
2-5 Expansion Cards
WARNING! Turn off your power when adding or re oving expansion cards or other
syste co ponents. Failure to do so ay cause severe da age to both
your otherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the docu entation for your expansion card and ake any necessary hardware or
software setting for your expansion card such as ju pers.
2. Re ove your co puter’s cover and the bracket plate on the slot you intend to use.
3. Align the card’s connectors and press fir ly.
4. Secure the card on the slot with the screen you re ove above.
5. Replace the co puter syste ’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
