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 695AS Motherboard
1-1 Feature of motherboard
The 695AS motherboard is design for use Intel PentiumIII /Celeron PPGA/FC-PGA CPU,
which utilize the Socket 370 design and the memory size expandable to 1.5GB.
This motherboard use the newest VIA Apollo Pro VT82C693A 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 695AS motherboard offers ULTRA ATA 66.
This provides speedier HDD throughout that boosts overall system performance.
The 695AS also has an integrated AC’97 2.1 CODEC on board which is fully compatible with
Sound Blaster Pro

that gives you the best sound quality and compatibility.
With 2 USB control as well as capability of expanding to 4 USB connectors, the 695AS meet
future USB demand also this motherboard has built-in hardware monitor function. This will
monitor and protect your computer.
The 695AS motherboard supports ACPI function such like Ring_In Wake Up, Ring_In Power
On, Wake On LAN, RTC Power On for OS Directed Power Management.
The Special fuction in BIOS SETUP can choose system clock step by step increasing between
66∼99Mhz, 100∼132Mhz, 133∼166Mhz to approach Over-Clock possiblilty. System auto
detection and reboot system use default frequency when system boot fail by overclocking.
This motherboard supports standard Synchronous DRAM (SDRAM) and Virtual Channel
Memory (VCM), in a flexible mix/match manner.
This motherboard provides high performance & meets future specification demand. It is
really wise choice for your 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.

2-3-3 Over clock Running
WARNING! This section is for experienced motherboard installer only. Over clocking
can result in system unstability or even shortening life of the processor.
After setting the Jumper 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 motherboard provides three 168-pin DUAL INLINE MEMORY MODULES (DIMM)
sites for memory expansion available from minimum memory size of 32MB to maximum
memory 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
Bank 2, 3 (DIMM2) SDRAM 32, 64, 128, 256, 512MB X1 32MB∼512MB

Total System Memory (Max. 1.5GB) 32MB∼1.5GB
NOTE! Make sure the total installed memory does not exceeds 1.5GB, 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
DIMM3 (BANK4+ BANK5)
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 fimly 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 strick 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
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
“Shared IRQ” or that the cards don’t need IRQ assignments. Conflicts will
arise between the two PCI groups that will make the system unstable or
cards inoperable.

2-6 Connectors, Headers
2-6-1 Connectors
(1) Power Connector (20-pin block) : POWER
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.

(8) Primary IDE Connector (40-pin block): IDE1
This connector supports the provided IDE hard disk ribbon cable. After connecting the
single plug end to motherboard, connect the two plugs at other end to your hard disk(s).
If you install two hard disks, you must configure the second drive to Slave mode by
setting its jumpers accordingly. Please refer to the documentation of your hard disk for
the jumper settings.

Pin 1
(9) Secondary IDE Connector (40-pin block): IDE2
This connector connects to the next set of Master and Slave hard disks. Follow the
same procedure described for the primary IDE connector. You may also configure two
hard disks to be both Masters using one ribbon cable on the primary IDE connector and
another ribbon cable on the secondary IDE connector.
