Introduction

The A7V266-E incorporates the VIA KT266A chipset to support AMD® socket A processors, as well as high-bandwidth DDR (double data rate) memory. The result is a motherboard that delivers optimal performance and features to fulfill the performance potential of AMD® socket A processors.

 

Features

DDR Memory

The A7V266-E supports up to 3GB of high-speed DDR ( Double Data Rate) PC2100/PC1600 SDRAM for a peak bandwidth of 2.1 GB/s. The ultra-fast 266 MHz memory bus provides enhanced system performance for intense gaming and multimedia applications.

 

6-Channel Onboard Audio
Experience high-quality 6-channel 3D surround audio with the optional C-Media CMI8738 audio controller. This unique chip eliminates the cost of an additional soundcard and adds dynamic realism to your favorite MP3s or DVDs.

 

Onboard RAID
Enhanced hard disk performance and features such as IDE RAID O (striping) and RAID 1 (mirror) are enabled via an onboard Promise RAID controller.

 

High Performance Standards

An AGP Pro/4X slot and an ULTRA-DMA 33/66/100 interface allows support of the most advanced graphics cards and hard drives.

 

Easy Overclocking

ASUS A7V266-E offers the most overclocking options available to maximize your system performance.

Easy DIP Switch or JumperfreeTM overclocking from BIOS

Layout

 

The layout of the Main Board is such that the user is able to identify the components.

These components include:

CPU Socket

Chip Set locations

ATX Power connection

Memory slots

AGP slot

PCI slots

IDE connectors

Floppy connectors

CMOS

Jumpers

Front Panel connectors

 

Hardware Setup

Onboard LED warns users when the motherboard is still receiving power.

Jumper settings

To changer the FSB

To change the CPU multiplier

To change the core voltage (Voltage Regulator Output Setting)

Memory support

Remember DDR memory has only one notch, SDRAM has two.

DDR has 184 pins, devided into two areas, 104 pins and 80 pins

SDRAM has 168 pins, divided into three areas, 88 pins, 60 pins, and 20 pins

This motherboard supports DDR DIMM sizes of:

256MB, 512MB, 1024MB for a total of 3GB of memory.

DIMMs that have more than 18 chips are not supported.

DPD (Serial Presence Detect) is supported

CPU

This board works with Socket A for AMD® Athlon XP / Athlon / Duron 550MHz ~ 1.6GHz+ CPU

Always use a heat Sink Fan that is rated for the selected CPU.

Expansion cards

There are 16 IRQ, but most are used. Only 6 IRQs are free for cards. If there is onboard audio, there will only be 4 IRQs free.

A Interrupt Request Table for this board is given to help with placemnet of the cards.

AGP

1 x AGP Pro/AGP 4X for video cards

Back Connectors

Mouse: Green PS2 6-pin female

Keyboard: Purple PS2 6-pin female

USB

COM1 and COM2 serial ports

Parallel port 25-pin female

Game port 15-pin female

Audio connectors

Floppy Connector - 34 pin

IDE Connector - 40 pin

Fan Headers

To supply power to fans from the motherboard

Front Panel Connectors

Beep Codes

One short beep - no error

Long beeps in loop - DIMM error

One beep followed by three more - Video error

High frequency beeps - CPU is over heating

Troubleshooting

Setting up the PC in a cool environment.

Heat is a leading cause for system failure, so find a room that does not get too hot.  Also, do be sure that the PC does not receive direct sunlight.

Limit exposure to dusty areas.

Limit tobacco smoke exposure.

Proper grounding of the P/S

 

POST

If POST fails, you may hear a beep code. There is no standard to these codes, but if beeps are heard, then check RAM and card seating.

If the video card fails, the system will sound a long beep followed by two short beeps.

After all system parts pass, a short beep is sounded and the system boots up.

 

To fix problems-

Use the Problem Solving Process

Gather data to define the problem clearly

Develop a plan, do research

Carry out the plan, recording your steps

Document the process

Monitor the results

 

 

Open class discussion

Researching what to buy.

What do we look for?

How do we gather information?

 

Troubleshooting

Your diagnoses is that 5 cards are defective in a PC you should_____

a) Recheck for software or I/O conflicts

b) Replace cards all at once

c) Replace cards one at a time

You have a PC with no video on a known good monitor. Pick the best order you should follow in tracking down the problem.

a) replace the video card, replace the monitor, replace the power supply, replace the system board, try a different monitor

b) check that PC and monitor are plugged in, check that monitor brightness is turned up, check that PC fan is running, remove all option cards

c) check PC supply voltages, replace video card, replace CPU

d) check that everything's plugged in, replace system board

e) check that everything's plugged in, replace hard drive, replace ram

Which of the following would be a logical first step in troubleshooting a PC?

a) Check the computer CMOS

b) Define the circumstances of the problem

c) Call the vendor

d) Define what applications are being used

After displaying the directory of a floppy disk, a different floppy is inserted into the drive. The contents of the original floppy continues to display regardless of the director requests on the other floppies placed in the drive. You remove the drive in question and install it into your test system, and it does not exhibit the problem. You should next replace the:

a) System's floppy drive device driver

b) Original IDE controller

c) Floppy drive ribbon cable

d) System's power supply

What questions could be asked to determine if a problem is software or hardware related? (choose all that apply)

a) Does the computer BEEP during the boot phase?

b) Did peripheral devices initialize, i.e. printers?

c) Will hardware components pass diagnostics?

d) Determine how many serial ports are installed in the system.

A keyboard locks up intermittently even when replaced with a new keyboard. What is the LEAST likely cause of the problem?

a) A second bad keyboard

b) The keyboard controller chip

c) The keyboard connector

d) The motherboard
