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:
=
100MHz
If CPU Clock
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
performance, thermal management becomes increasingly crucial when building computer systems. Maintaining the proper
WARNING!
thermal environment is key to reliable operation. As such, the
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.

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.
Clear ESCD
Normally, you leave this field Clear ESCD to reset Extended System
Configuration Data (ESCD) when you exit Setup if you have installed a new
add-on and the system reconfiguration has caused such a serious conflict that
the operating system can not boot. The settings are: Enabled and Disabled.
Resource Controlled By
The Award Plug and Play BIOS has the capacity to automatically configure
all of the boot and Plug and Play compatible devices. However, this capability
means absolutely nothing unless you are using a Plug and Play operating system
such as Windows® 98/2000/XP. If set to “Auto”, BIOS will automatically
assign the IRQ to each device. If set to “manual”, you have to choose specific
resources by going into each of the sub menu that follows this field (a sub
menu is preceded by a “¾”). The settings are: Auto (ESCD), Manual.
3-25
MS-6738 Micro ATX Mainboard
IRQ Resources
The items are adjustable only when Resources Controlled By is set to Manual.
Press <Enter> and you will enter the sub-menu of the items.
IRQ Resources list IRQ 3/4/5/7/9/10/11/12/14/15 for users to set each IRQ a
type depending on the type of device using the IRQ. Settings are:
PCI Device
For Plug & Play compatible devices designed for PCI
bus architecture.
Reserved
The IRQ will be reserved for further request.
PCI/VGA Palette Snoop
When set to Enabled, multiple VGA devices operating on different buses can
handle data from the CPU on each set of palette registers on every video
device. Bit 5 of the command register in the PCI device configuration space is
the VGA Palette Snoop bit (0 is disabled). For example, if there are two VGA
devices in the computer (one PCI and one ISA) and the:
VGA Palette
Snoop Bit Setting
Action
Disabled
Data read or written by the CPU is only directed to the
PCI VGA device’s palette registers.
Enabled
Data read or written by the CPU is directed to both the
PCI VGA device’s palette registers and the ISA VGA
device’s palette registers, permitting the palette registers
of both VGA devices to be identical.
The setting must be set to Enabled if any ISA bus adapter in the system requires
VGA palette snooping.
Assign IRQ For VGA/USB
These settings specify the IRQ line for specified VGA/USB device. Setting
options: Disabled, Enabled.

Frequency/Voltage Control
Use this menu to specify your settings for frequency/voltage control.
Auto Detect DIMM/PCI Clk
This item is used to auto detect the PCI/DIMM slots. When set to Enabled,
the system will remove (turn off) clocks from empty PCI/DIMM slots to
minimize the electromagnetic interference (EMI). Setting options: Enabled,
Disabled.
Spread Spectrum
When the motherboard 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.
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. Settings: Disabled, +/-0.25%, 0.37%, +/-0.50%, +/-0.75%.
CPU Host/SDRAM/PCI Clock
This item specifies the clock frequency of CPU host bus (FSB), SDRAM and
PCI bus. It provides a method for end users to overclock the processor. If the
item shows Default, the setting will use the default value for the clock frequency
of CPU host bus, SDRAM and PCI bus.

memory. You will be prompted to confirm the password. Retype the password and press <Enter>. You may also press <Esc> to abort the selection and
not enter a password.
To clear a set password, just press <Enter> when you are prompted to enter
the password. A message will show up confirming the password will be
disabled. Once the password is disabled, the system will boot and you can
enter Setup without entering any password.
When a password has been set, 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 have BIOS to request
a password each time the system is booted. This would prevent unauthorized
use of your computer. The setting to determine when the password prompt is
required is the Security Option of the Advanced BIOS Feature menu. If the
Security Option is set to System, the password is required both at boot and at
entry to Setup. If set to Setup, password prompt only occurs when you try to
enter Setup.

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

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-6738 Micro 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-6738 Micro 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.
