System Overview

The EP-3C1A is designed with Intel® 820 chipset. The Intel® 820 chipset includes
MCH (FW82820), ICH (FW82801) and FWH (N82802AB) three chips. The
Intel® 820 chipset is the third generation desktop chipset designed for Intels FC­PGA package architecture processor and the first chipset to support the 4X
capability of the AGP 2.0 Interface Specification. The MTH (82805AA) provides
the capability to support 100MHz SDRAMs on DIMMs socket. A new chipset
component interconnect, the hub interface, is designed into the Intel® 820 chipset
to provide more efficient communication between chipset components.

Support of AGP 4X, 100MHz SDRAM and the hub interface provides a balanced
system architecture for the Pentium® III or later socket 370 architecture proces­sor minimizing bottlenecks and increasing system performance. By increasing
memory bandwidth to 1.6GB/s through the use of AGP 4X, the Intel® 820 chipset
will deliver the data throughput necessary to take advantage of the high perfor­mance provided by the powerful Pentium® III or later socket 370 architecture
processor.

The Intel® 820 chipset architecture removes the requirement for the ISA expan­sion bus that was traditionally integrated into the I/O subsystem of Intel chipsets.
This removes many of the conflicts experienced when installing hardware and
drivers into legacy ISA systems. The elimination of ISA will provide true plug-and
play for the Intel® 820 platform.

Intel® 820 chipset contains four core components: the Memory Controller Hub
(MCH), Memory Translator Hub (MTH), the I/O Controller Hub (ICH) and the
Firmware Hub (FWH). The MCH integrates the 133MHz, Pentium® II/III proces­sor bus controller, AGP 2.0 controller, 100MHz SDRAM controller and a high­speed hub interface for communication with the ICH. The ICH integrates an
UltraATA/66 controller, USB host controller, LPC interface controller, FWH
interface controller, PCI interface controller, and a hub interface for communica­tion with the MCH. The Intel® 820 chipset will provide the data buffering and
interface arbitration required to ensure that system interfaces operate efficiently
and provide the system bandwidth necessary to obtain peak performance the
Pentium® III or later socket 370 architecture.

Overview

Intel Coppermine processors of Flip-chip pin grid
array (FC-PGA) Package

These Coppermine-128K and Coppermine-256K processor is the next addition to
the P6 micro architecture product family. The FC-PGA package is a new addition to
the Intel IA-32 processor line and hereafter will be referred to as the Coppermine
FC-PGA processor, or simply The processor. The package utilizes the same 370­pin zero insertion force socket (PGA370) used by the Intel Celeron processor.
Thermal solutions are attached directly to the back of the processor core package
without the use of a thermal plate or heat spreader.

The Coppermine processor, like the Intel Celeron, Intel Pentium II and Pentium III
in the P6 family processor, implement a Dynamic Execution micro architecture --­a unique combination of multiple branch prediction, data flow analysis, and specula­tive execution. This enable these processors to deliver higher performance than the
Intel Pentium processor, while maintaining binary compatibility with all previous
Intel Architecture processors. The processor also executes Intel MMX technology
instructions for enhanced media and communication performance just as its prede­cessor the Intel Pentium III processor. Additionally the Coppermine FC-PGA pro­cessor executes streaming SIMD (Single-Instruction Multiple Data) Extensions for
enhanced floating point and 3-D application performance. The concept of proces­sor identification, via CPUID, is extended in the processor family with the addition
of a processor serial number. The processor utilizes multiple low-power states
such as AutoHALT, Stop-Grant, Sleep and Deep Sleep to conserve power during idle
times.

The processor includes an integrated on-die, 128KB or 256KB, 8-way set associa­tive level-two (L2) cache with a separated 16KB level one (L1) instruction cache
and 16KB level one (L1) data cache. These cache arrays run at the full speed of the

processor core. As with the Intel Pentium III processor, the Coppermine FC-PGA
processor has a dedicated L2 cache bus, thus maintaining the dual independent bus
architecture to deliver high bus bandwidth and performance. Memory is cacheable
for 4GB/64GB of addressable memory space, allowing significant headroom for
desktop system.

Installation and Removal

Installation:

Install the processor and the fan heatsink using the Installation Notes provided with
the boxed processor. The FC-PGA processor with package dimensions is provided
to aid in the design of heatsink and clip solutions as well as demonstrate where pin
side capacitors will be located on the processor. First, raise the handle of the 370­pin socket. Carefully install the processor into the 370-pin socket making sure that
none of the pins are bent. Then close the handle of the socket. Next install the fan
heatsink. Make sure to install the heatsink onto the processor after the processor
has been inserted into the 370-pin socket. Place the fan heatsink onto the processor
such that the integrated clip lines up with the sockets attach tabs. This will align
the fan cable with the PGA370 mark on the 370-pin socket. Remember not to damage
the thermal interface pad. Attach
the clip onto the sockets attach
tabs. (A small tool, such as a pen,
may make this process easier.) Take
care to consider potential scraping
of the motherboard underneath the
370-pin socket attach tabs. Connect
the attached fan power cable to the
motherboard connector and quickly
power on the system to verify that
the processor fan is running.

Removal:

To simplify the following process, consider removing the motherboard from the chas­sis before removing the processor. First, unplug the fan power cable from the
motherboards connector. Then pull the integrated clip away from the sockets tab
nearest the fan cable. (A small tool, such as a pen or screwdriver, may make this
process easier.) Once the clip is free, slowly lift the fan heatsink straight up away
from the socket and the processor. (If the processor has been in operation for a long

IntroductionEP-3C1A

Page 1-7

period of time, then this step may require some extra force; this is because the heat
dissipated from the processor will have affected the thermal interface pad) Next, lift up
the handle of the 370-pin socket. Finally, carefully remove the processor from the
socket making sure not to bend any of the processor pins.

Accelerated Graphics Port
(AGP or A.G.P.)

Typically, 3D graphics rendering requires a tremendous amount of memory, and
demands ever increasing throughput speed as well. As 3D products for the
personal computer become more and more popular, these demands will only
increase. This will cause a rise in costs for both end users and manufacturers.
Lowering these costs as well as improving performance is the primary motivation
behind AGP. By providing a massive increase in the bandwidth available between
the video card and the processor, it will assist in relieving some of these pressures
for quite sometime.

The EP-3C1A provides the AGP 2.0 interface. The AGP Interface Specification
revision 2.0 enhances the functionality of the original AGP Interface Specifica­tion (revision 1.0) by allowing 4X data transfers (4 data samples per clock) and 1.
5 volt (power supply) operation. The AGP 2.0 interface, along with Direct
Rambus memory technology, allows graphics controllers to access main memory
at over 1GB/s. In order to match the 1X, 2X and 4X AGP Card. The EP-3C1A
used the Universal AGP connector. To maximize add-in flexibility. (such as 1.5
volt for 1X, 2X and 4X or 3.3 volt for 1X and 2X AGP Card).

Ultra ATA/66

The ICH provides two channel Ultra ATA/66 Bus Master IDE controller, that
support Ultra ATA/66 protocols, perfect for such demanding applications as real­time video, multimedia, and high performance operating system. A new IDE cable
is required for Ultra ATA/66. This cable is an 80 conductor cable; however the
connectors are, of course, backwards compatible with ATA/33.

Hardware Monitoring

Hardware monitoring allows you to monitor various aspects of your systems
operations and status. The features include CPU temperature, voltage and RPM of
fan.

IntroductionEP-3C1A

Page 1-9

EP-3C1A Form-Factor

The EP-3C1A is designed with ATX form factor - the latest industry standard of
chassis. The ATX form factor is essentially a Baby-AT baseboard rotated 90
degrees within the chassis enclosure and a new mounting configuration for the
power supply. With these changes the processor is relocated away from the
expansion slots, allowing them all to hold full length add-in cards. ATX defines
a double height aperture to the rear of the chassis which can be used to host a
wide range of onboard I/O. Only the size and position of this aperture is
defined, allowing PC manufacturers to add new I/O features (e.g.; TV input, TV
output, joystick, modem, LAN, audio, etc.) to systems. This will help systems
integrators differentiate their products in the marketplace, and better meet your
needs.

 By integrating more I/O down onto the board and better positioning the

hard drive and floppy connectors material cost of cables and add-in cards is
reduced.

 By reducing the number of cables and components in the system, manufac-

turing time and inventory holding costs are reduced and reliability will
increase.

 By using an optimized power supply, it's possible to reduce cooling costs

and lower acoustical noise. An ATX power supply, which has a side­mounted fan, allows direct cooling of the processor and add-in cards
making a secondary fan or active heatsink unnecessary in most system
applications.

ATX
POWER SUPPLY

Power-On/Off (Remote)

The EP-3C1A has a single 20-pin connector for ATX power supplies. For ATX power
supplies that support the Remote On/Off feature, this should be connected to the
systems front panel for system Power On/Off button. The systems power On/Off
button should be a momentary button that is normally open.

The EP-3C1A has been designed with Soft Off" functions. You can turn Off the
system from one of two sources: The first is the front panel Power On/Off button,
and the other is the "Soft Off" function (coming from the EP-3C1As onboard circuit
controller) that can be controlled by the operating system. Windows 95/98 will
control this when the user clicks that they are ready to Shutdown the system.

Note: For maintaining the SDRAM power during STR (ACPI S3) function, it

is strongly recommend to use ATX power supplies that have a +5VSB
current of (>=) 1A (1000mA). Please check the 5VSBs specification

that has been printed on the ATX power supplys outer case.

The EP-3C1A supports (3) 168-pin DIMMs (Dual In-line Memory Module). Sockets
are available for 3.3Volt (power level) Synchronous Dynamic Random Access
Memory (SDRAM) of 8, 16, 32, 64, 128MB or 256MB.

 This board supports SPD DIMMs Modules only.
 This board supports 64Mbit and 128Mbit SDRAM technologies.

The registered DIMM Supports 32Mx4 128Mbit Memory Modules only.

 We recommend using at least 125MHz (-8ns) SDRAM DIMM at the 100MHz

(or higher) FSB as timing becomes more critical at these higher speeds.

 DIMM SDRAM may be 83MHz (-12ns), 100MHz (-10ns) or 125MHz (-8ns)

bus speed.

4-3 Advanced Chipset Fea tures

This section allows you to configure the system based on the specific features of
the installed chipset. This chipset manages bus speeds and access to system memory
resources, such as DRAM and the external cache. It also coordinates communica­tions between the conventional ISA bus and the PCI bus. It must be stated that these
items should never need to be altered. The default settings have been chosen be­cause they provide the best operating conditions for your system. The only time you
might consider making any changes would be if you discovered that data was being
lost while using your system.

DRAM Settings (This field is no function)

The first chipset settings deal with CPU access to dynamic random access memory
(DRAM). The default timings have been carefully chosen and should only be altered
if data is being lost. Such a scenario might well occur if your system had mixed
speed DRAM chips installed so that greater delays may be required to preserve the
integrity of the data held in the slower memory chips.

4-10 Supervisor/User Passw ord Setting

You can set either supervisor or user password, or both of then. The differences
between are:

supervisor password : can enter and change the options of the setup menus.
user password : just can only enter but do not have the right to change the

options of the setup menus. When you select this function, the following message
will appear at the center of the screen to assist you in creating a password.

ENTER PASSWORD:

Type the password, up to eight characters in length, and press <Enter>. The pass­word typed now will clear any previously entered password from CMOS memory.
You will be asked to confirm the password. Type the password again and press
<Enter>. You may also press <Esc> to abort the selection and not enter a password.
To disable a password, just press <Enter> when you are prompted to enter the
password. A message will confirm the password will be disabled. Once the pass­word is disabled, the system will boot and you can enter Setup freely.

PASSWORD DISABLED.

When a password has been enabled, you will be prompted to enter it every time you
try to enter Setup. This prevents an unauthorized person from changing any part of
your system configuration.
Additionally, when a password is enabled, you can also require the BIOS to request a
password every time your system is rebooted. This would prevent unauthorized use
of your computer.
You determine when the password is required within the BIOS Features Setup Menu
and its Security option (see Section 3). If the Security option is set to System, the
password will be required both at boot and at entry to Setup. If set to Setup, prompt­ing only occurs when trying to enter Setup.

The 4 Speakers System

This Audio Adapter provides 2 wave channels(front/rear), known as the 4 speakers
system. When games or application programs via DirectSound® 3D or A3D

®

interface locate the sound sources to the listeners back, the two rear speakers
will work to enhance the rear audio positional effect, so as to complement the
insufficiency of using only two front speakers to emulate the audio effect. The
following is the hardware installation and the software setups:

1.The speaker installation.

Connect the front pair speakers to the Line-out jack of the audio adapter, and
then connect rear pair speakers to Line-in/Rear jack of the audio adapter. The
original Line-in can be moved to Aux-in.

2.The positions of the speakers

Put your speakers the way the following picture suggests, so as to avail yourself
to the best audio result.

3. The mixer setup

There is a 4 speakers option in the volume control of the mixer, and when you
enable this option, it means the rear speakers are connected to Line-in/Rear
jack. When Line-in/Rear jack is connected to other external Line-in sources,
please DO NOT enable this option in order to avoid hardware conflicts. Regard­ing rear speaker option, you can turn on or turn off the output of the back
speakers, and adjust the volume, to have the rear/front speakers have the same
volume.

When all the procedures have been completed, there will be an infrared signal
coming from the SPDIF/OUT of the optical fiber of the sound card.

Please note that signal beam may cause severe damage to the eyes. For your
safety,please point the output end to a piece of white paper to check if thebeam is
in function.

Please connect the output signal to the MD input,then play the music via the MP3
player:

Please note that in playback, if there is no gap longer than three seconds between
each track, the MD can not recognize the tracks and will record all of them into one.
It is recommended that you set the gap time to 3~5 seconds to meet all type of MD

requirements.
