Thanks for choosing AOpen AK77-8X / AK77-8XN. The AK77-8X / AK77-8XN is AMD®Socket 462 motherboard (M/B) based on
the ATX form factor featuring the VIA Apollo KT400 chipset. As high performance chipset built in the M/B, the AK77-8X /
AK77-8XN AMD®Socket 462 series Athlon™ & Duron™ and AthlonXP™ processor (with CPU Overheat Protection circuit to
Athlon™XP CPU only) and 200/266/333MHz EV6 system bus. In the AGP performance, it has one AGP slot and supports AGP
/8X mode and pipelined spilt-transaction long burst transfer up to 2.1GB/sec. With high bandwidth 200/266/333MB/s 8-bit V-Link
Host Controller, DDR333(PC2700) and DDR266(PC2100)DDR SDRAM can be applied to the AK77-8X / AK77-8XN and the
maximum memory size can be up to 3GB. The on-board IDE
controller supports Ultra DMA 66/100/133 mode and the
transfer rate up to 133MB/s. Further flexibility can be achieved
by taking advantage of the Communication and Network Riser
(CNR) card option that allows audio and modem configuration
on a single baseboard design. More than that, on the strength
of RealTek RTL8100BL controller on board, which is an
highly-integrated Platform LAN Connect device, it provides
10/100M bps Ethernet for office and home use (AK77-8XN only).
Besides, the AK77-8X / AK77-8XN has an AC97 CODEC
Realtek ALC650 chipset onboard for providing high
performance and magic surround stereo sound to let people
enjoy working with it. More than that, this motherboard supports
USB 2.0 function with a fancy speed of up to 480Mbps. Now,
let’s enjoy all features from AOpen AK77-8X / AK77-8XN.

CPU
Supports AMD® Socket 462 series CPU with 200/266/333 MHz EV6 Bus designed for Socket 462 technology.
Athlon: 600MHz~1.4GHz
Duron: 600MHz~1.3GHz
AthlonXP: 1500+(1.33GHz)~2800+(2.25GHz)
Chipset
The VIA Apollo KT400 consists of the KT400 V-Link DDR Host system controller and the VT8235 highly integrated V-Link Client
PCI/LPC controller. The Host system controller provides superior performance between the CPU, SDRAM, AGP bus, and V-Link
interface with pipelined, burst, and concurrent operation. The VT8235 V-Link Client controller is a highly integrated PCI/LPC
controller. Its internal bus structure is based on 66MHz PCI bus that provides 4x bandwidth compare to previous generation
PCI/ISA bridge chips. The VT8235 integrated Client V-Link controller with 200/266MB/s bandwidth between Host/Client V-Link
interface, providing a V-Link-PCI and V-Link-LPC controller.
Ultra DMA 66/100/133 Bus Master IDE
Comes with an on-board PCI Bus Master IDE controller with two connectors that supports four IDE devices in two channels,
supports Ultra DMA 66/100/133, PIO Modes 3 and 4 and Bus Master IDE DMA Mode 4, and supports Enhanced IDE devices.

Expansion Slots
Including six 32-bit/33MHz PCI, one CNR and one AGP 8X slots. The PCI local bus throughput can be up to 132MB/s. The
Communication & Nectworking Riser (CNR) slot provided from AK77-8X / AK77-8XN can support CNR interface for a
Modem/Audio card. The Accelerated Graphics Port (AGP) specification provides a new level of video display sophistication and
speed. The AGP video cards support data transfer rate up to 2.1GB/s. As AK77-8X / AK77-8XN includes one AGP expansion
slot for a bus mastering AGP graphic card, For AD and SBA signaling, AK77-8X / AK77-8XN can support 133MHz 2X/4X/8X
mode. Of six PCI slots provided, all of them support master PCI slots for arbitration and decoding functions.
Memory
With VIA Apollo KT400 chipset, the AK77-8X / AK77-8XN can support Double-Data-Rate (DDR) RAM. The DDR RAM interface
allows zero wait state bursting between the RAM and the data buffers at 333/266/200 MHz. The six banks of DDR RAM can be
composed of an arbitrary mixture of 64, 128, 256, 512MB x N DDR RAM and maximum up to 3GB. The AK77-8X / AK77-8XN
allows DDR RAM to run at either synchronous or pseudo-synchronous mode with the host CPU bus frequency
(333/266/200MHz).
LAN Port (AK77-8XN only)
On the strength of RealTek RTL8100BL controller on board, which is an highly-integrated Platform LAN Connect device, it
provides 10/100 Mbps Ethernet for office and home use.
On-board AC97 Sound
AK77-8X / AK77-8XN uses the AC97 CODEC RealTek ALC650 chip, which supports high quality of 5.1 Channel audio effects.
This on-board audio includes a complete audio recording and playback system.

Six USB 2.0 Connectors
Provides three ports, six USB connectors for USB interface devices, such as mouse, keyboard, modem, scanner, etc. Please be
noted that USB 2.0, with fancy speed up to 480Mbps, is 40 times faster than the traditional ones. Except for the speed increase,
USB 2.0 supports old USB 1.0/1.1 software and peripherals, offering impressive and even better compatibility to customers.
1MHz Stepping Frequency Adjustment
Provides “1MHz Stepping Frequency Adjustment” function in the BIOS. This magic function allows you to adjust CPU FSB
frequency from 100~191 by 1MHz stepping, and lets your system get maximum performance.
Watch Dog Timer
Includes AOpen “Watch Dog Timer” function that can auto-reset system in 4.8 seconds when you fail to system overclocking.
Power Management/Plug and Play
The AK77-8X / AK77-8XN supports the power management function that confirms to the power-saving standards of the U.S.
Environmental Protection Agency (EPA) Energy Star program. It also offers Plug-and-Play, which helps saving users from
configuration problems, thus making the system much more user-friendly.

This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards,
and other components. Always observe the following precautions before you install a system
component.
1. Do not remove a component from its protective packaging until you are ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a
component. If a wrist strap is not available, maintain contact with the system unit throughout
any procedures requiring ESD protection.

When you read this online manual and start to assemble your computer system, you may find some of functions are called
“Manufacturer Upgrade Optional”, and some are called “User Upgrade Optional”. Though all AOpen motherboards include many
amazing and powerful features, in some situations, these powerful features are not used to every user. Hence, we changed
some key features as “Manufacturer Upgrade Optional” for you to choose. Some optional functions that can be upgraded by
users, we call them “User Upgrade Optional”. As for those optional functions that can’t be upgraded by ourselves, we call them
“Manufacturer Upgrade Optional”. If needed, you can contact our local distributors or resellers for purchasing “User Upgrade
Optional” components, and again you can visit AOpen official web site: http://english.aopen.com.tw/ for more detail information.
