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:
w Socket A (PGA 462)
w 200MHz system interface based on the Alpha EV6 bus protocol.
w Three out-of-order, superscalar, pipelined Multimedia Units.
w Three out-of-order, superscaler, pipelined Integer Units.
w Fixed-sized internal instruction formats (MacroOPs).
w 72-entry Instruction Control Units.
w AMD enhanced 3DNow! technology
w L1 and L2 caches.
w Dynamic branch prediction.
Socket A is the name for AMDs 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 worlds most powerful x86
processors. They easily deliver the highest integer, floating-point, and 3D multimedia performance for applications running on x86 platforms around.

IntroductionEP-8KTA
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.
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-8KTA
EP-8KT A F orm-Factor
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.

Power-On/Off (Remote)
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-8KTAs
onboard circuit controller) that can be controlled by the operating system such
asWindows® 95/98 or Windows®2000.

System Memory Configuration
Memory Layout
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.

AWARD BIOS SETUP
Main Menu
Awards 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.

4-10 Supervisor/User Password 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.

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 selections 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
