Introduction
AthlonTM Processors
The AMD AthlonTM 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:
Socket A (PGA 462)
266/333MHz system interface based on the Alpha EV6 bus protocol.
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 AMDs new socketed interface designed to support AMD
AthlonTM 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 AthlonTM 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.
It features full-speed, on-chip cache memory, a 266/333MHz front side system bus,
and enhanced 3DNow! technology. The AMD AthlonTM processor is targeted at
the performance segment, and as such will have more cache memory and higher
clock speeds.

Introduction
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 board provides the AGP 3.0 interface. The AGP interface can support external
AGP slot (1.5V only) with AGP 8X/4X and Fast Write Transactions. The AGP
Interface Specification revision 3.0 enhances the functionality of the original AGP
Interface Specification by allowing 8X data transfers (8 data samples per clock) and
1.5 volt (Power supply) operation. Supports Maximum AGP interface bandwidth 2.
1GB/s. (1.5 volt AGP Card supports only).
Ultra ATA/66/100/133
The MCP provides two independent ATA133 IDE controllers, supporting standard
programmable input/output (PIO) and Direct Memory Access (DMA) mode
operations, as well as UltraDMA-133/100/66/33 standards for a maximum data
transfer rate of 133MBps per channel.
LAN (Optional)
The motherboard mounts the LAN chipset. It allows the mainboard to connect to a
local area network by means of a network hub.
Hardware Monitoring
Hardware monitoring allows you to monitor various aspects of your system
operations and status. The features include CPU temperature, voltage and RPM of
fan.
Page 1-3
Introduction
Serial ATA (Optional)
The evolutionary serial ATA interface replaces the standard parallel ATA physical
storage interface. The serial ATA specification provides scalability and allows
future enhancements to the computing platform. Serial technology overcomes
performance limits of parallel interface architecture, meeting the escalating need for
faster data throughput in servers and storage devices.
Serial ATA is backward compatible with current software and runs on existing
architecture without modification. The serial ATA interface cable requires lower
voltages and uses smaller cable connectors, providing ease of installation. You can
easily upgrade storage devices that are compatible with the serial ATA interface
specification. Serial ATA supports all ATA and ATAPI devices, including high
capacity removable devices, optical devices, tape storage devices, and zip drives.
Serial ATA is completely software compatible with parallel ATA, requiring no
modification to your operating system.
Page 1-4
Introduction
Mainboard Form-Factor
The board 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.

Power-On/Off (Remote)
The board has a 20-pin ATX connector for power supplies (Figure 4). For power
supplies that support the Remote On/Off feature, this should be connected to the
mainboard front panel PW_ON connector for the computer power On/Off button.
The board has been designed with Soft Off" function. You can turn off the system
two ways: pressing the front panel power On/Off button, using the "Soft Off"
function (incorporated in the mainboards onboard circuit controller) that can be
controlled by an operating system such as Windows®ME/2000/98SE/XP.
Note: For maintaining the DDR 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 5VSBs specification that has been
printed on the ATX power supplys outer case.
Note: The board requires a minimum of 250 Watt ATX power supply to operate. Your
system configuration (amount of memory, add-in cards, peripherals, etc.) may
exceed the minimum power requirement but to ensure that adequate power is
provided, use a 300 Watt (or greater) ATX power supply.
