The AMD Athlon is a seventh-generation micro architecture with an integrated L2  
cache, which is powerful enough to support the bandwidth requirements of a large  
range of applications, hardware, graphics, and memory technologies. These  
processors implement advanced design techniques such as:

Three out-of-order, superscalar, pipelined Multimedia Units.  
Three out-of-order, superscaler, pipelined Integer Units.  
Fixed-sized internal instruction formats (MacroOPs).  
72-entry Instruction Control Units.  
AMD enhanced 3DNow!™ technology  
L1 and L2 caches.  
Dynamic branch prediction.  
Socket A is the name for AMD’s new socketed interface designed to support both  
AMD Duron and AMD Athlon processors. This innovation is made possible by  
integrating the L2 cache memory on chip with the processor. Socket A will help  
enable smaller enclosures, and ultimately result in a wider variety of solutions in  
the market.  
The AMD Duron & Athlon processors in the Socket A format continue to deliver  
the ultimate performance for cutting-edge applications. Both bring to desktop  
systems running industry-standard x86 software superscalar RISC performance.  
Being provided in the Socket A format they are the world’s most powerful x86  
processors. They easily deliver the highest integer, floating-point, and 3D multi-  
media performance for applications running on x86 platforms around.

Introduction  
The AMD Duron processor is derived from the AMD Athlon processor core. It  
features full-speed, on-chip cache memory, a 200MHz front side system bus, and  
enhanced 3DNow!™ technology. Although both processors are related, there are  
key differences. The AMD Athlon processor is targeted at the performance  
segment, and as such will have more cache memory and higher clock speeds.  
Ac c e le ra t e d Gra p h ic s Po r t  
(AGP o r 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.  
Ha rd w a re Mo n it o rin g  
Hardware monitoring allows you to monitor various aspects of your systems  
operations and status. The features include CPU temperature, voltage and RPM of  
fan.

Introduction  
EP-8KTA  
EP -8 KTA Fo r m -Fa c t o r  
The EP-8KTA is designed with ATX form factor - the new industry standard of  
chassis. 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, 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.

Pow e r-On /Off (Re m o t e )  
The EP-8KTA 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-8KTA 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-8KTA’s  
onboard circuit controller) that can be controlled by the operating system such  
asWindows® 95/98 or Windows®2000.

The EP-8KTA supports (3) PC133 168-pin DIMMs (Dual In-line Memory  
Module). The DIMMs is for SDRAM (Synchronous DRAM) only.  
DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or  
125MHz (8ns) bus speed.  
If you use both 50ns and 60ns memory you must configure  
your BIOS to read 60ns.  
When using Synchronous DRAM we recommend using the  
4 clock variety over the 2 clock.  
Figure 2 and Table 1 show several possible memory configurations.

support the External Modem Ring-in Power ON function. Once users connect the  
external modem to COM1 or COM2, the EP-8KTA 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 2-3 after you finished the system  
installation.

Step 2: You can enjoy the Keyboard Power ON function (KBPO) by pressing any  
key and BUTTON only to turn on your 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® 95/98 or Windows®2000.  
Notes: ATX version 2.0 specification has recommended you use the power  
supply with 0.72A(720mA) in 5.0VSB. With our EP-8KTA mainboard,  
the 5.0VSB standby power only has to be > = 0.72A (720mA) then you  
can enjoy this unique benefit. However, the ATX power supply which is  
< 0.72A (720mA) is still applicable to your system by placed JP13 at the  
position 1-2 to disable this feature.

3 -6 S TR (S u s p e n d To RAM) Fu n c t io n  
The EP-8KTA supports the STR power management state by maintaining the  
appropriate states on the SDRAM interface signals. The power source must be  
kept alive to the SDRAM during STR (ACPI S3). Advanced Configuration  
Power Interface (ACPI) provides more Energy Saving Features for operating  
systems that supporting Instant ON and QuickStartTM function.  
1. To enable the ACPI function and use the STR functionally to save your system  
energy, you are recommended to confirm the following requirements:  
a. Please do install all ACPI qualified add-on cards such as AGP, LAN,  
Modem cards.  
b. In BIOS, please select “ ACPI function: Enable” and “ACPI Suspend Type:  
S3(STR)” in the Power Management Setup menu.  
c. Then, please install the Windows® 98SE or Windows® 2000.  
d. Restart your system.  
e. Getting in to the “Advanced” of the Power Management icon of Control  
Panel, and selecting the “Stand By” in the Power Buttons.  
2. Getting start with STR function, please click the START button and choose  
Shut Down. Then, select the Stand By option in the Shut Down Windows box  
to get into STR mode.  
Here are the differences between STR power saving mode and Green (or  
Suspend) mode:  
a. It is the most advanced Power Management mode  
b. It cuts all the power supplied to peripherals except to Memory - max. power  
saving  
c. It saves and keeps all on-screen data including any executed applications to  
SDRAM.

AWARD BIOS S ETUP  
Ma in Me n u  
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.

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 pass-  
word 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 pass-  
word 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.

Pressing <Enter> on this item asks for confirmation:  
Save to CMOS and EXIT (Y/N)? Y  
Pressing “Y” stores the selections made in the menus in CMOS – a special section  
of memory that stays on after you turn your system off. The next time you boot  
your computer, the BIOS configures your system according to the Setup selec-  
tions stored in CMOS. After saving the values the system is restarted again.  
Exit Without Saving  
Pressing <Enter> on this item asks for confirmation:  
Quit without saving (Y/N)? Y  
This allows you to exit Setup without storing in CMOS any change. The previous  
selections remain in effect. This exits the Setup utility and restarts your computer.
