Hardware Setup

Central Processing Unit: CPU

The mainboard supports AMD® Athlon™, Athlon™ XP and Duron™

processors in the 462 pin package. The mainboard uses a CPU socket called
Socket-462 for easy CPU installation. When you are installing the CPU, make

sure the CPU has a heat sink and a cooling fan attached on the top to
prevent overheating. If you do not find the heat sink and cooling fan, contact

your dealer to purchase and install them before turning on the computer.

CPU Core Speed Derivation Procedure

CPU Clock multipled by Core/Bus ratio equals the CPU core speed.

For example:
If CPU Clock = 100MHz

Core/Bus ratio = 14

then CPU core speed = Host Clock x Core/Bus ratio

= 100MHz x 14
= 1.4 GHz

Thermal Issue for CPU

As processor technology pushes to faster speeds and higher

!

WARNING!

processor must be maintained in the specified thermal requirements. AMD
recommends the use of high performance thermal interface material.

AMD Athlon™/Duron™ processor with a speed of 600MHz and above
requires LARGER heatsink and fan. You also need to add thermal grease
between the CPU and heatsink to improve heat dissipation. Then, make sure
that the CPU and heatsink are securely fastened and in good contact with each
other. These are needed to prevent damaging the processor and ensuring
reliable operation.

You can check AMD’s web site for more information.

SDRAM Frequency, SDRAM CAS# Latency, Row Precharge Time, RAS

3-13

MS-6764 ATX Mainboard

Pulse Width, RAS to CAS Delay and SDRAM Bank Interleave
automatically to be determined by BIOS based on the configurations on
the SPD. Selecting User allows users to configure these fields manually.

SDRAM Frequency

Use this item to configure the clock frequency of the installed SDRAM.
Settings options: SPD, 200MHz, 266MHz.

SDRAM CAS# Latency

This controls the timing delay (in clock cycles) before SDRAM starts
a read command after receiving it. Settings: 2, 2.5 (clocks). 2 (clocks)
increases the system performance the most while 2.5 (clocks) provides
the most stable performance.

Row Precharge Time

This item controls the number of cycles for Row Address Strobe (RAS)
to be allowed to precharge. If insufficient time is allowed for the RAS
to accumulate its charge before DRAM refresh, refresh may be
incomplete and DRAM may fail to retain data. This item applies only
when synchronous DRAM is installed in the system. Available
settings: Auto, 2T, 3T.

RAS Pulse Width

This setting allows you to select the number of clock cycles allotted
for the RAS pulse width, according to DRAM specifications. The
less the clock cycles, the faster the DRAM performance. Settings:
Auto, 6T, 5T.

3-14

RAS to CAS Delay

When DRAM is refreshed, both rows and columns are addressed
separately. This setup item allows you to determine the timing of the
transition from RAS (row address strobe) to CAS (column address
strobe). The less the clock cycles, the faster the DRAM performance.
Setting options: Auto, 3T, 2T.

Bank Interleave

This field selects 2-bank or 4-bank interleave for the installed SDRAM.
Disable the function if 16MB SDRAM is installed. Settings: Auto,
Disabled, 2-Way and 4-Way.

BIOS Setup

SDRAM Burst Length

This setting allows you to set the size of Burst-Length for DRAM.
Bursting feature is a technique that DRAM itself predicts the address of
the next memory location to be accessed after the first address is accessed.
To use the feature, you need to define the burst length, which is the actual
length of burst plus the starting address and allows internal address counter
to properly generate the next memory location. The bigger the size, the
faster the DRAM performance. Settings: 4 QW, 8 QW.

SDRAM 1T Command

This setting controls the SDRAM command rate. Selecting Enabled
allows SDRAM signal controller to run at 1T (T=clock cycles) rate.
Selecting Disabled makes SDRAM signal controller run at 2T rate. 1T is
faster than 2T. Setting options: Disabled, Enabled.

Fast Command

technology allows the CPU to write directly to the graphics card without
passing anything through the system memory and improves the AGP 4X
speed. Select Enabled only when the installed AGP card supports the
function.

AGP Aperture Size

This setting controls just how much system RAM can be allocated to
AGP for video purposes. The aperture is a portion of the PCI memory
address range dedicated to graphics memory address space. Host cycles
that hit the aperture range are forwarded to the AGP without any
translation. The option allows the selection of an aperture size of 4MB,
8MB, 16MB, 32MB, 64MB, 128MB, and 256 MB.

AGP Master 1 W/S Write

The field allows users to insert one wait state into the AGP write cycle.
Settings: Enabled, Disabled.

AGP Master 1 W/S Read

The field allows users to insert one wait state into the AGP read cycle.
Settings: Enabled, Disabled.

AGP Read Synchronization

The field allows you to enable or disable the AGP Read Synchronization
feature. Settings: Enabled, Disabled.

PCI Delay Transaction

The chipset has an embedded 32-bit posted write buffer to support delayed
transactions cycles so that transactions to and from the ISA bus are buffered
and PCI bus can perform other transactions while the ISA transaction is
underway. Select Enabled to support compliance with PCI specification
version 2.1. Setting options: Enabled, Disabled.

BIOS Setup

PNP/PCI Configurations

This section describes configuring the PCI bus system and PnP (Plug & Play)
feature. PCI, or Peripheral Component Interconnect, is a system which allows
I/O devices to operate at speeds nearing the speed the CPU itself uses when
communicating with its special components. This section covers some very
technical items and it is strongly recommended that only experienced users
should make any changes to the default settings.

Plug and Play Aware O/S

When set to Yes, BIOS will only initialize the PnP cards used for booting
(VGA, IDE, SCSI). The rest of the cards will be initialized by the PnP operating
system like Windows® 98, 2000 or ME. When set to No, BIOS will initialize
all the PnP cards. Select Yes if the operating system is Plug & Play.

Clear NVRAM

The ESCD (Extended System Configuration Data) NVRAM (Non-volatile
Random Access Memory) is where the BIOS stores resource information for
both PNP and non-PNP devices in a bit string format. When the item is set to
Yes, the system will reset ESCD NVRAM right after the system is booted up
and then set the setting of the item back to No automatically.

PCI Latency Timer

This item controls how long each PCI device can hold the bus before another
takes over. When set to higher values, every PCI device can conduct
transactions for a longer time and thus improve the effective PCI bandwidth.

Frequency/Voltage Control

Use this menu to specify your settings for frequency/voltage control.

Spread Spectrum

When the motherboard’s clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread Spec­trum function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are reduced to flatter curves. If you do not have any EMI
problem, leave the setting at Disabled for optimal system stability and
performance. But if you are plagued by EMI, setting to Enabled for EMI
reduction. Remember to disable Spread Spectrum if you are overclocking
because even a slight jitter can introduce a temporary boost in clockspeed
which may just cause your overclocked processor to lock up.

CPU FSB Clock

This item allows you to select the CPU Front Side Bus clock frequency (in
MHz) and overclock the processor by adjusting the FSB clock to a higher
frequency.

CPU Ratio/Vcore (V)

When you select Load High Performance Defaults, a message as below appears:

Pressing ‘Enter’ loads the default BIOS values that enable the best system
performance but may lead to a stability issue.

MSI Reminds You...

The option is for power or overclocking users only. Use of high
performance defaults will tighten most timings to increase the
system performance. Therefore, a high-end system configuration
is a must, which means you need high-quality VGA adapter, RAM
and so on. We don’t recommend that users should apply the
high performance defaults in their regular systems. Otherwise,
the system may become unstable or even crash. If the system
crashes or hangs after enabling the feature, please CLEAR CMOS

Troubleshooting

Q: Should I update my BIOS, once a new BIOS is released?

A: A new BIOS is usually released due to the following reasons:

1. New function is supported

2. New BIOS source code

3. Bugs are found

4. Customer-specific request

When we release a new BIOS, there's usually a release note attached which

lists the reason for the release. Refer to this release note and decide for

yourself if upgrading to the new BIOS will be worth it. A word of advice,

though, do not upgrade to the new BIOS, unless you really have to.

Q: How do I update the BIOS?

A: Please refer to http://www.msi.com.tw/support/bios/note.htm for details.

Q: How do I identify the BIOS version?

A: Upon boot-up, the 1st line appearing after the memory count is the BIOS

version. It is usually in the format:

1. For older model number:

AG76 091096 where:

1st digit refers to BIOS maker as A = AMI(R) W = AWARD(R) P = PHOENIX

(R).

2nd digit refers to the internal chipset code.

3rd digit refers to the processor class as 5 = 486, 7 = 586, 8 = 686.

4th digit is incremental.

091096 refers to the date this BIOS is released.

2. For newer model number:

W5139MS V1.0 091096 where:

1st digit refers to BIOS maker as A = AMI(R) W = AWARD(R) P = PHOENIX

(R).

2nd - 5th digit refers to the model number.

T-3

MS-6764 ATX Mainboard

6th - 7th digit refers to the customer as MS = all standard customers.

V1.0 refers to the BIOS version.

091096 refers to the date this BIOS is released.

Q: After flashing the bios and rebooting the system, the screen went blank.

A: For AMI BIOS

Rename the desired AMI BIOS file to AMIBOOT.ROM and save it on a

floppy disk. e.g. Rename A569MS23.ROM to AMIBOOT.ROM

Insert this floppy disk in the floppy drive. Turn On the system and press

and hold Ctrl-Home to force update. It will read the AMIBOOT.ROM file

and recover the BIOS from the A drive.

When 4 beeps are heard you may remove the floppy disk and restart the

computer.

For Award BIOS

Make a bootable floopy disk

Copy the Award flash utility & BIOS file to the said floppy disk

Create an autoexec.bat with "awdfl535 biosfilename" in the content e.g.

awdfl535 a619mj21.bin

Boot up system with the said floppy (it will take less than 2 minutes before

screen comes out)

Re-flash the BIOS & reboot.

ACPI (Advanced Configuration & Power Interface)

This power management specification enables the OS (operating system) to control the
amount of power given to each device attached to the computer. Windows 98/98SE,
Windows 2000 and Windows ME can fully support ACPI to allow users managing the
system power flexibly.

AGP (Accelerated Graphics Port)

A new, high-speed graphics interface that based on PCI construction and designed
especially for the throughput demands of 3-D graphics. AGP provides a direct channel
(32-bit wide bus) between the display controller and main memory for high graphics
quality and performance.

Bluetooth

Bluetooth refers to a worldwide standard for the wireless exchange of data between two
devices. Bluetooth requires that a low-cost transceiver chip be included in each device.
The tranceiver transmits and receives in a previously unused frequency band of 2.45
GHz that is available globally (with some variation of bandwidth in different countries).
In addition to data, up to three voice channels are available. Each device has a unique 48­bit address from the IEEE 802 standard. Connections can be point-to-point or
multipoint. The maximum range is 10 meters. Data can be exchanged at a rate of 1
megabit per second (up to 2 Mbps in the second generation of the technology).

BIOS (Basic Input/Output System)

On PCs, an essential software that contains all the control code of input/output inter­face (such as keyboard, disk drives, etc.). It executes hardware test on booting the
system, starts the OS, and provides an interface between the OS and the components.
The BIOS is stored in a ROM chip.

Bus

A set of hardware lines within the computer system, through which the data is trans­ferred among different components. In a PC, the term bus usually refers to a local bus
that connects the internal components to the CPU and main memory.

Cache

A special memory subsystem that is used to speed up the data transfer. It stores the

G-1

MS-6764 ATX Mainboard

contents of frequently accessed RAM locations and the addresses where these data
items are stored.

Chipset

A collection of integrated chips designed to perform one or more related functions. For
example, a modem chipset contains all the primary circuits for transmitting and receiv­ing data; a PC chipset provides the electronic interfaces between all subsystems.

Clock Cycle

Clock cycle (or tick) is the smallest unit of time recognized by a device. For personal
computers, clock cycles generally refer to the main system clock, which runs at 66
MHz. This means that there are 66 million clock cycles per second. Since modern
CPUs run much faster (up to 533 MHz), the CPU can execute several instructions in a
single clock tick.

CMOS (Complementary Metal-Oxide Semiconductor)

CMOS is a widely used type of semiconductor, which features high speed and low
power consumption. PCs usually contain a small amount of battery-powered CMOS
memory to retain the date, time, and system setup parameters.

DRAM (Dynamic RAM)

A most common type of computer memory. It usually uses one transistor and a
capacitor to represent a bit. As the development of technology, the memory type and
specification used in computer becomes variety, such as SDRAM, DDR SDRAM, and
RDRAM. For further instruction, please see the table below:

ECC Memory (Error Correcting Code Memory)

A type of memory that contains special circuitry for testing the accuracy of data and
correcting the errors on the fly.

EEPROM

Acronym for Electrically Erasable Programmable Read-Only Memory. An EEPROM
is a special type of PROM that can be erased by exposing it to an electrical charge. Like
other types of PROM, EEPROM retains its contents even when the power is turned
off. Also like other types of ROM, EEPROM is not as fast as RAM. EEPROM is
similar to flash memory (sometimes called flash EEPROM). The principal difference is
that EEPROM requires data to be written or erased one byte at a time whereas flash
memory allows data to be written or erased in blocks. This makes flash memory faster.

EIDE

Short for Enhanced IDE, a newer version of the IDE mass storage device interface
standard developed by Western Digital Corporation. It supports data rates of between
4 and 16.6 MBps, about three to four times faster than the old IDE standard. In
addition, it can support mass storage devices of up to 8.4 gigabytes, whereas the old
standard was limited to 528 MB. Because of its lower cost, enhanced EIDE has
replaced SCSI in many areas. There are four EIDE modes defined. The most common
is Mode 4, which supports transfer rates of 16.6 MBps. There is also a new mode,
called ATA-3 or Ultra ATA, that supports transfer rates of 33 MBps.

EISA (Extended Industry Standard Architecture)

EISA is a standard bus (computer interconnection) architecture that extends the ISA
standard to a 32-bit interface. It was developed in part as an open alternative to the
proprietary Micro Channel Architecture (MCA) that IBM introduced in its PS/2
computers. EISA data transfer can reach a peak of 33 megabytes per second.

ESCD (Extended System Configuration Data)

It is a format for storing information about Plug-and-Play (PnP) devices in the BIOS.
Windows and the BIOS access the ESCD area each time you re-boot your computer

External Cache

Short for Level 2 cache, cache memory that is external to the microprocessor. In
general, L2 cache memory, also called the secondary cache, resides on a separate chip
from the microprocessor chip. Although, more and more microprocessors are including
L2 caches into their architectures.

G-3

MS-6764 ATX Mainboard

IDE (Integrated Drive Electronics)

A type of disk-drive interface widely used to connect hard disks, CD-ROMs and tape
drives to a PC, in which the controller electronics is integrated into the drive itself,
eliminating the need for a separate adapter card. The IDE interface is known as the
ATA (AT Attachment) specification.

IEEE 1394

A new, high speed external bus standard, also known as FireWire or iLink, which
supports data transfer rates of up to 400 Mbps for connecting up to 63 external
devices.

Internal Cache

Short for Level 1 cache, a memory cache built into the microprocessor. The L1 cache is
also called the primary cache.

IrDA (Infrared Data Association)

A group of device vendors, including computer, component and telecommunications,
who have developed a standard for transmitting data via infrared light waves. This
enables you to transfer data from one device to another without any cables.

IRQ (Interrupt Request Line)

IRQs are hardware lines over which devices can send interrupt signals to the
microprocessor. When you add a new device to a PC, you sometimes need to set its
IRQ number by setting a DIP switch. This specifies which interrupt line the device
may use. IRQ conflicts used to be a common problem when adding expansion boards,
but the Plug-and-Play specification has removed this headache in most cases.

ISA (Industry Standard Architecture)

ISA is a standard bus (computer interconnection) architecture that is associated with
the IBM AT motherboard. It allows 16 bits at a time to flow between the motherboard
circuitry and an expansion slot card and its associated device(s). Also see EISA and
MCA.

LAN (Local Area Network)

A computer network that covers a relatively smaller area, such as in a building or an
enterprise. It is made up of servers, workstations, shared resources, a network operat­ing system and a communications link. These individual PCs and devices on a LAN are
known as “nodes”, and are connected by cables to access data and devices anywhere on
the LAN, so that many users can share expensive devices and data.

LBA (Logical Block Addressing)

Logical block addressing is a technique that allows a computer to address a hard disk
larger than 528 megabytes. A logical block address is a 28-bit value that maps to a
specific cylinder-head-sector address on the disk. 28 bits allows sufficient variation to
specify addresses on a hard disk up to 8.4 gigabytes in data storage capacity. Logical
block addressing is one of the defining features of Enhanced IDE (EIDE), a hard disk
interface to the computer bus or data paths.

LED (Light Emitting Diode)

A semiconductor device that converts electrical energy into light. Since it lights up
(usually red) when electricity is passed through it, it is usually used for the activity
lights on computer’s component, such as disk drivers.

LPT (Line Printer Terminal)

Logical device name for a line printer; a name reserved by the MS-DOS for up to three
parallel printer ports: LPT1, LPT2, and LPT3. It is frequently used by the OS to
identify a printer.

Overclocking

Overclocking is resetting your computer so that the microprocessor runs faster than the
manufacturer-specified speed (for example, setting an Intel 166 MHz (megahertz)
microprocessor to run at 200 Mhz).

PCI (Peripheral Component Interconnect)

A local bus standard developed by Intel that first appeared on PCs in late 1993. PCI
provides “plug and play” capability and allows IRQs to be shared. The PCI controller
can exchange data with the system's CPU either 32 bits or 64 bits at a time.

PnP (Plug and Play)

A set of specifications that allows a PC to configure itself automatically to work with
peripherals. The user can "plug" in a peripheral device and "play" it without configur­ing the system manually. To implement this useful feature, both the BIOS that sup­ports PnP and a PnP expansion card are required.

POST (Power On Self Test)

During booting up your system, the BIOS executes a series of diagnostic tests, include
checking the RAM, the keyboard, the disk drives, etc., to see if they are properly
connected and operating.

G-5

MS-6764 ATX Mainboard

PS/2 Port

A type of port developed by IBM for connecting a mouse or keyboard to a PC. The
PS/2 port supports a mini DIN plug containing just 6 pins. Most modern PCs equipped
with PS/2 ports so that the special port can be used by another device, such as a
modem.

RAID

RAID (Redundant Array of Independent Disks; originally Redundant Array of Inex­pensive Disks) is a way of storing the same data in different places (thus, redundantly)
on multiple hard disks. By placing data on multiple disks, I/O operations can overlap in
a balanced way, improving performance. Since multiple disks increases the mean time
between failure (MTBF), storing data redundantly also increases fault-tolerance.

SCSI

Acronym for Small Computer System Interface. Pronounced "scuzzy," SCSI is a par­allel interface standard used by Apple Macintosh computers, PCs, and many UNIX
systems for attaching peripheral devices to computers. SCSI interfaces provide for
faster data transmission rates (up to 80 megabytes per second) than standard serial and
parallel ports. In addition, you can attach many devices to a single SCSI port, so that
SCSI is really an I/O bus rather than simply an interface.

USB (Universal Serial Bus)

A hardware interface for low-speed peripherals such as the keyboard, mouse, joystick,
etc. USB provides a maximum bandwidth of 12 Mbit/sec (Mbps) for connecting up to
127 peripheral devices to PC. USB features hot swap capability and multiple data
streams, allows external devices to be plugged in and unplugged without turning the
system off.

Virus

A program or a piece of code that infects computer files by inserting in those files
copies of itself. The virus code is buried within an existing program, and is activated
when that program is executed. All the viruses are man-made, and often have damaging
side effects.

WLAN

Acronym for wireless local-area network. Also referred to as LAWN. A type of local­area network that uses high-frequency radio waves rather than wires to communicate
between nodes.
