Overview

Pentium® II or Pentium® III Processor

The Pentium® II or Pentium® III Processor (The Pentium® III Processor as 300/
100MHz, 350/100MHz, 400/100MHz and 450/100MHz speed with 512K-L2
cache Versions.) is the follow-on to the Pentium® Processor. The Pentium® II or
Pentium® III Processor, like the Pentium® Pro processor, implements a Dynamic
Execution micro-architecture -- a unique combination of multiple branch
prediction, data flow analysis, and speculative execution. This enables the
Pentium® II Processor to deliver higher performance than the Pentium

®

processor, while maintaining binary compatibility with all previous Intel architec­ture processors.

A significant feature of the Pentium® II or Pentium® III Processor, from a system
perspective, is the built-in direct multiprocessing support. In order to achieve
multiprocessing, and maintain the memory and I/O bandwidth to support it, new
system designs are needed. For systems with dual processors, it is important to
consider the additional power burdens and signal integrity issues of supporting
multiple loads on a high speed bus. The Pentium® II or Pentium® III Processor
card supports both uni-processor and dual processor implementations.

The Pentium® II or Pentium® III Processor utilizes Single Edge Contact (S.E.C.)
(Figure 1) cartridge packaging technology. The S.E.C. cartridge allows the L2
cache to remain tightly coupled to the processor, while maintaining flexibility
when implementing high performance processors into OEM systems. The second
level cache is performance optimized and tested at the cartridge level. The S.E.C.
cartridge utilizes surface mounted core components and a printed circuit board
with an edge finger connection. The S.E.C. cartridge package introduced on the
Pentium® II Processor will also be used in future Slot 1 processors.

The S.E.C. cartridge has the following features: a thermal plate, a cover and a PCB
with an edge finger connection. The thermal plate allows standardized heatsink
attachment or customized thermal solutions. The thermal plate enables a reusable
heatsink to minimize fit issues for serviceability, upgradeability and replacement.
The full enclosure also protects the surface mount components. The edge finger
connection maintains socketabilty for system configuration. The edge finger
connector is denoted as ‘Slot 1 connector’ in this and other documentation.

IntroductionEP-6ZXM

Page 1-3

The entire enclosed product is called the Pentium® II or Pentium® III Processor.
The packaging technology and each of the physical elements of the product are
referred to using accurate technical descriptions. This allows clear reference to
the products as just a processor. This is the model used in past packaging tech­nologies like PGA, TCP, PQFP, DIP, etc.

S.E.C. Cartridge Terminology

• Pentium® II or Pentium® III Processor
The new enclosed card packaging technology is called a “Single Edge
Contact cartridge.” This is similar to previous names for packaging
technology such as PGA or TCP.

• Processor card
The green PCB (with or without components on it)

• Processor core
The silicon on the PLGA package on the PCB

• Cover
The plastic cover on the opposite side from the thermal plate.

• Slot 1
The slot that the S.E.C. cartridge plugs into, just as the Pentium® Pro
processor uses Socket 8.

• Retention mechanism
Formerly ‘retention module’ the dual posts, etc. that holds the cartridge in
place.

• Thermal plate
The heatsink attach­ment plate.

• Heat sink supports
The support pieces that
are mounted on the
mainboard to provide
added support for
heatsinks.

The Pentium® II or Pentium® III Processor is the first product to utilize the S.E.C.

cartridge technology and Slot 1 connector. Unless otherwise noted, any refer­ences to “Pentium® II Processor,” “Pentium® II or Pentium® III Processor/Slot 1
processor” or “Pentium III Processor” will apply to both the Pentium® II Proces­sor desktop processors.

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.

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-6ZXM

Page 1-5

EP-6ZXM Form-Factor

The EP-6ZXM is designed with MicroATX form factor - the new industry
standard of chassis. The MicroATX 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.
MicroATX 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, etc.) to systems. This will help systems
integrators differentiate their products in the marketplace, and better meet your
needs.

• Smaller size promotes a smaller system size.

• I/O shield does not need to be retooled in an ATX 2.01 or later. The
mainboard should be used in an ATX 2.01 (or later) compliant case.

• A smaller power supply can be used. High integration on mainboard
reduces the system costs.

The EP-6ZXM is equipped with an I/O back panel. Please use the appropriate I/O
shield (figure 3).

MicroATX
POWER SUPPLY

Power-On/Off (Remote)

The EP-6ZXM has a single 20-pin connector for MicroATX power supplies. For
MicroATX/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-6ZXM 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 the
button, and the other is the "Soft Off" function (coming from the EP-6ZXM’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: Based on the implementation of the Intel 440ZX AGPset the EP-6ZXM is

able to provide multiple front side bus (FSB) frequencies for Slot 1 proces­sors and memory operations. The mainboard's FSB is easily selected by
jumper JP3 listed above to match the FSB required by your processor. When
using the 100MHz FSB (or higher) you must use PC100 (or better) compli­ant SDRAM.

Memory is an important component of any motherboard. When selecting
memory for use on the EPoX brand motherboard we recommend using
only the finest quality modules. EPoX would like to stress that using non­compliant PC100 SDRAM modules with a 100MHz (or higher) FSB
severely compromises the integrity of the system.

System Memory Configuration

Memory Layout

The EP-6ZXM supports (3) 168-pin DIMMs (Dual In-line Memory Module).
The DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized
DRAM).

• We recommend not mixing SDRAM DIMM and EDO DIMM

together.

• EDO DIMM can only be used with the 66MHz FSB.

• 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.

Installing a Pentium® II or Pentium® III Processor

The EP-6ZXM uses the Single Edge Contact (SEC) slot for a Pentium® II/III
processor packaged in an SEC cartridge. The SEC slot is not compatible with
other non-Pentium® II/III processors.

Please have ready the following list of components so that we may install the
processor onto the motherboard.

1. Heat sink support (top/bottom piece)

2. Pentium® II/III processor heat sink

3. Intel Pentium® II/III Processor

OK, now that you have all of your components ready, we can start.

First, please refer to figure 6 below, and follow the direction to lift up the
fixed foldable pentium® II/III Retention Mechanism. This pre-installed
device is designed for you to install Pentium® II/III CPU more easier and
to avoide any damage on the board due to overtightening the four screws.

One thing must be kept in your mind that please make sure to lift upright
the foldable parts of the Retention module to fit and install CPU properly.

Figure 6

Now we are going to install the heatsink support base piece (figure 7) onto the
motherboard. There is both a large and small hole (figure 8) so that the base will
only fit in one direction. This piece needs to be pushed into the holes firmly until
it is seated.

Now we are ready to install the SEC Cartridge (Pentium® II/III Processor) into
the Retention Module. The SEC Cartridge is mounted by sliding the SEC Car­tridge into the Retention Module and letting it slide all the way down. Once it
reaches the bottom make sure you press firmly on SEC cartridge to firmly secure
into the Slot 1 Socket.

Installation

EP-6ZXM

Page 3-9

Now we need to secure the heatsink with the top half of the support (figure 9).
Take the top piece of the support and slide it into the bottom fin (figure 9) on the
heatsink and then push forward until it clips into the bottom base (figure 7) that is
already there (figure 9).

External Modem Ring-in Power

ON and Keyboard Power ON

Functions (KBPO)

On the basis of bounded functions in I/O chipset, the two serial ports are able to
support the External Modem Ring-in Power ON function. Once users connect the
external modem to COM1 or COM2, the mainboard allows users to turn on their
system through the remote and host's dial-up control.

Exclusive Keyboard Power ON Function

To innovate a unique feature to benefit users, we devoted the easiest and most
convenient way to turn on your system based on the the ATX power supply.

How to work with it

Step 1: Please check JP13 at the position 1-2 after you finished the system

installation.

Step 2: Push the momentary switch (J3 PW-ON) to turn on your system and then

push again to hold for more than 4 seconds to turn it off affter counting
memory as soon as you turn it on.

Step 3: You can enjoy the Keyboard Power ON function (KBPO) by pressing

any 1 key, Hot key (Ctrl-F1, F2.....F12), Password (A maximum of 5

charac ters can be entered.) and BUTTON only to turn on your system.
Please refer to the BIOS Integrated peripherals setup for detail (Page
4-23).The BIOS Default is keyboard Hot key <Ctrl> - <F1> to turn on
the system. Your system will be turned on automatically, after releasing

the keys. To power off you system, you can use the Soft-OFF function
under Windows 95.

Notes:

1. Intel ATX version 2.0 specification has recommended you use the power
supply with 0.72A(720mA) in 5.0VSB. With our mainboard, the 5.0VSB
standby power only has to be > = 0.1A (100mA) then you can enjoy this
unique benefit. However, the ATX power supply which is < 0.1 (100mA) is
still applicable to your system by placed JP13 at the position 2-3 to disable
this feature.

AWARD BIOS SETUP

BIOS Instructions

Award’s ROM BIOS provides a built-in Setup program which allows user to
modify the basic system configuration and hardware parameters. The modified
data will be stored in a battery-backed CMOS, so that data will be retained even
when the power is turned off. In general, the information saved in the CMOS
RAM will stay unchanged unless there is a configuration change in the system,
such as hard drive replacement or a device is added.

It is possible for the CMOS battery to fail, this will cause data loss in the CMOS
only. If this does happen you will need to reconfigure your BIOS settings.

To enter the Setup Program :

Power on the computer and press the <Del> key immediately, this will bring you
into the BIOS CMOS SETUP UTILITY.

4-5 PNP/PCI Configuration

The PNP/PCI configuration program is for the user to modify the PCI/ISA IRQ
signals when various PCI/ISA cards are inserted in the PCI or ISA slots.

WARNING: Conflicting IRQ’s may cause the system to not find certain devices.

Figure 6: PCI Configuration Setup

PNP OS Installed: Do you have a PNP OS installed on your system. The default
is No.

Yes: Select if you are using a PNP OS.
No: Select if your OS does not support PNP.

Resources Controlled By: Who controlled the system PNP/PCI resources.

The default is Manual.
Manual: PNP Card’s resources will be controlled manually. You can set which

IRQ-X and DMA-X are assigned to PCI/ISA PNP or Legacy ISA Cards.

recorded into ESCD (Extended System Configuration Data), you can
set this field to Enabled in order to clear ESCD.

IRQ-3 to IRQ-15 assigned to: These settings allow IRQ’s to be reserved for
Legacy ISA device use exclusively or be available for use with PNP devices.
These options are only displayed if “Resources Controlled By” is set to manual.

Used MEM base addr: The Used MEM base addr (CB00, CC00, D000, D400,
D800, DC00) and Used MEM Length (8K, 16K, 32K, 64K) are used to support
some specific ISA Legacy cards with requested memory space below 1M address.
Now with these two functions, users can define where the used memory address
is located and its length of the legacy area that is used by the legacy device to
avoid the memory space conflict. For example, if you select “D000” for Used
MEM base addr” and “16K” for “Used MEM Length”, that means the address
region D000H-D3FFFH is occupied by ISA legacy cards, and thus BIOS will not
assign this region for PnP/ISA and PCI cards. The default is N/A.

Assign IRQ For USB: This item allows BIOS to assign whether IRQ is with
USB or not. If you have not connect the USB device. Can release the IRQ for
other device. The default is Enabled.

4-9 IDE HDD Auto Detection

The “IIDE HDD auto detection” utility is a very useful tool, especially when you
do not know which kind of hard disk type you are using. You can use this utility to
detect the correct disk type installed in the system automatically. But now you
can set HARD DISK TYPE to Auto in the STANDARD CMOS SETUP. You don’t
need the “IIDE HDD AUTO DETECTION” utility. The BIOS will Auto-detect the
hard disk size and model on display during POST.

Figure 8: IDE HDD Auto Detection

Note: HDD Modes

The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE NORMAL
mode
Generic access mode in which neither the BIOS nor the IDE controller will make
any transformations during accessing.
The maximum number of cylinders, head & sectors for NORMAL mode are
1024, 16 & 63.

If user set his HDD to NORMAL mode, the maximum accessible HDD size will
be 528 Megabytes even though its physical size may be greater than that!

LBA (Logical Block Addressing) mode: A new HDD accessing method to
overcome the 528 Megabyte bottleneck. The number of cylinders, heads &
sectors shown in setup may not be the number physically contained in the HDD.
During HDD accessing, the IDE controller will transform the logical address
described by sector, head & cylinder into its own physical address inside the
HDD. The maximum HDD size supported by LBA mode is 8.4 GigaBytes which is
obtained by the following formula:

no. Cylinder (1024)
x no. Head ( 255)
x no. Sector ( 63 )
x bytes per sector ( 512)

8.4 GigaBytes

LARGE mode: Extended HDD access mode supported by Award Software.
Some IDE HDDs contain more than 1024 cylinder without LBA support (in some

cases, user do not want LBA). The Award BIOS provides another alternative to
support these kinds of LARGE mode.

CYLS HEADS SECTOR MODE

1120 16 59 NORMAL
560 32 59 LARGE

BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by
dividing it by 2. At the same time, the number of heads is multiplied by 2. A
reverse transformation process will be made inside

INT 12h in order to access the right HDD address!
Maximum HDD size:

no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63 )
x bytes per sector ( 512)

BIOS

EP-6ZXM

Page 4-27

Note: To support LBA or LARGE mode of HDDs, there must be some software

involved. All the software is located in the Award HDD Service Routine
(INT 13h). It may fail to access a HDD with LBA (LARGE) mode selected
if you are running under an Operating System which replaces the whole
INT 13h.

UNIX operating systems do not support either LBA or LARGE and must utilize
the Standard mode. UNIX can support drives larger than 528MB.

The “SAVE & EXIT SETUP” option will bring you back to the boot up procedure
with all the changes you just recorded in the CMOS RAM.

4-11 Exit Without Saving

The “EXIT WITHOUT SAVING” option will bring you back to normal boot up
procedure without saving any data into CMOS RAM.

All old data in the CMOS will not be destroyed.

CPU Clock Frequency Selection In BIOS Setting.

There is a special function for CPU over-clocking requirement which can be
chosen and set by BIOS or set by JP3 (The undocumented jumper setting from
103MHz to 133MHz), please refer to the following steps for adjustment.

1. Enter the BIOS CMOS setup program. (If your system was operated at
66MHz)

2. Choose “Chipset Features Setup” in main menu.

3. Use “Page down” (or+) / “Page up (or -) to choose CPU clock frequency
as one of 66.8, 75MHz and 83.3MHz.
(Note: There are 66.8, 75 and 83.3MHz for 66MHz pentium II CPU
CLOCK frequency show only).

4. Press “Save & Exit setup” to complete BIOS setting.

If screen becomes blank or system can’t boot anymore after above setting. that
means your CPU couldn’t be capable of supporting overclock, and you have to
follow the steps below to recover the CPU clock frequency.

Step 1: Power the system off. (J3 PW-ON)
Step 2: Press <INS> (Insert) key while powering on the system, system will

function with 66MHz external frequency at this moment which depends
on what kind of CPU on board.

Step 3: Please choose lower frequency and try again.

Warning:

We do not guarantee all CPUs can be over-clocked (When the undocumented set
by BIOS[75 and 83.3MHz] or by JP3[103 to 133MHz]), it depends on CPU
design and the peripherals you are using; it’s vitally important to use faster
peripherals (faster SDRAM, AGP, I/O card...) to come with the higher CPU clock
frequency.
Please set apporpriate CPU CLOCK frequency to make the system stable.
