This chapter provides you with the information about hard­ware setup procedures for MS-6557 mainboard. While doing the
installation, be careful in holding the components and follow the
installation procedures. For some components, if you install in the
wrong orientation, the components will not work properly.

Use a grounded wrist strap before handling computer
components. Static electricity may damage the components.

Mainboard Setup

Chapter 2

2-2

The mainboard supports Intel® Pentium

TM

4 processors (Willimate

478 and Northwood 478). The mainboard uses a CPU socket called Socket 478

for easy CPU installation. While 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 or purchase them
before installing the CPU.

Central Processing Unit: CPU

Overheating

Overheating will seriously damage the CPU and system, al­ways make sure the cooling fan can work properly to protect
the CPU from overheating.

Replacing the CPU

While replacing the CPU, always turn off the ATX power sup­ply or unplug the power supply’s power cord from grounded
outlet first to ensure the safety of CPU.

Mainboard Setup

2-3

CPU Installation Procedures

1. Turn off the power and unplug

the power cord before install­ing the CPU.

2. Pull the lever sideways away

from the socket. Make sure
to raise the lever up to a 90­degree angle.

3. Look for the gold arrow. The
gold arrow should point to­wards the lever pivot. The
CPU can only fit in the correct
orientation.

4. If the CPU is correctly
installed, the pins should be
completely embedded into the
socket.

Any violation of the correct
installation procedures may
cause permanent damages to
your mainboard.

5. Press the CPU down firmly into

the socket and close the lever.

As the CPU is likely to move
while the lever is being
closed, always close the le­ver with your fingers press­ing tightly on top of the CPU
to make sure the CPU is prop­erly and completely embed­ded into the socket.

The CPU cooler included in the packing is designed specially for MS­6243 barebone. It is different from other CPU cooler of PentiumTM4. See the
follows for the features:

z Copper Material

The heatsink is made of copper that has better heat-disseminating effect.

z Shockproof Effect

The cooler has good shockproof effect through the mechanical combi

nation design of CPU fan and heatsink.

z Small Size

Contrast to normal CPU cooler, the small size takes up less space.

z Special Fan Design

The CPU fan has ball bearing solution. The reliability is better than

sleeve solution. It is suitable for Slim PC.

z High Density Fan Fins

The CPU cooler has high density fan fins than normal CPU cooler. It is

ideal for heat disseminating.

Attaching CPU Cooler

2. Use 4 screws to secure

the CPU cooler.

1. Put the CPU cooler on the CPU.

* The four screws of CPU cooler
are built-in.

* The front part of screw is de­signed for shockproof. While
securing the cooler, the front
part of screw can not be em­bedded into the hole
completely.

The mainboard provides two sockets for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) and supports the memory size up to 2 GB.
You can install PC2100/DDR266 or PC1600/DDR200 modules into the DDR
DIMM slots.

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM,
but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as
opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM mod­ules rather than 168-pin DIMM modules used by SDR SDRAM. T wo types of
DDR are available at the time of writing: PC1600 & PC2100. PC1600 DDR SDRAM
running at 100MHz will produce about 1.6GB/s memory bandwidth. PC2100
running at 133MHz will produce 2.1GB/s memory bandwidth. High memory
bandwidth makes DDR an ideal solution for high performance PC, worksta­tions and servers.

The graphics data sent to the digital monitor use Transition Minimized
Differential Signaling (T.M.D.S.) technology. TMDS uses an encoding
algorithm to 8-bit of data into a 10-bit transition minimized, DC balanced
character, which are transition-minimized to reduce EMI with copper
cables and DC-balanced for transmission over fiber optic cables. The
TMDS algorithm also provides robust clock recovery for greater skew
tolerance with longer cables or low cost short cables.

There is a CMOS RAM on board that has a power supply from external
battery to keep the data of system configuration. With the CMOS RAM, the
system can automatically boot OS every time it is turned on. That battery has
long life time for at least 5 years. If you want to clear the system configuration,
use the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions
below to clear the data:

The motherboard provides one jumper for you to set the computer’s

Boot T o OS/2

This allows you to run the OS/2® operating system with DRAM larger than
64MB. When you choose No, you cannot run the OS/2® operating system
with DRAM larger than 64MB. But it is possible if you choose Yes.

CPU L1 & L2 Cache

Cache memory is additional memory that is much faster than conventional
DRAM (system memory). When the CPU requests data, the system trans­fers the requested data from the main DRAM into cache memory, for even
faster access by the CPU. This setting enables/disables the internal cache
(also known as L1 or level 1 cache) and external cache (also known as L2 or
level 2 cache). Settings are: Enabled and Disabled.

System BIOS Cacheable

Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh,
resulting in better system performance. However, if any program writes to this
memory area, a system error may result. Setting options: Enabled, Disabled.

C000, 32k Shadow

This item specifies how the contents of the adapter ROM named in the item are
handled. Settings are described below:

Flash Protection

This function protects the BIOS from accidental corruption by unauthorized
users or computer viruses. When enabled, the BIOS’ s data cannot be changed
when attempting to update the BIOS with a Flash utility. To successfully
update the BIOS, you’ll need to disable this BIOS Flash Write Control function.
You should enable this function at all times. The only time when you need to
disable the function is when you want to update the BIOS. After updating the
BIOS, you should immediately re-enable it to protect the BIOS against viruses.

Option Description

Disabled The specified ROM is not copied to RAM.
Enabled The contents of specified ROM are copied to RAM

for faster system performance.

CAS# Latency

The field controls the CAS latency, which determines the timing de­lay before SDRAM starts a read command after receiving it. Setting
options: 2 Clocks and 3 Clocks. 2 Clocks increases system perform­ance while 3Clocks provides more stable system performance.

RAS# Precharge

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: 2 Clocks, 3 Clocks.

RAS# to CAS# Delay

This field allows you to set the number of cycles for a timing delay
between the CAS and RAS strobe signals, used when DRAM is
written to, read from or refreshed. Fast speed offers faster perform­ance while slow speed offers more stable performance. Settings: 3
Clocks, 2 Clocks.

Precharge Delay

The field specifies the idle cycles before precharging an idle bank.
Settings: 7 Clocks, 6 Clocks, 5 Clocks.

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, 8 (QW).

ACPI Standby State

This item specifies the power saving modes for ACPI function. Options are:

S1/POS The S1 sleep mode is a low power state. In this state, no

system context is lost (CPU or chipset) and hardware
maintains all system context.

S3/STR The S3 sleep mode is a lower power state where the infor-

mation of system configuration and open applications/
files is saved to main memory that remains powered while
most other hardware components turn off to save energy.
The information stored in memory will be used to restore
the system when a “wake up” event occurs.

Auto OS driver determines the best mode for ACPI standby

state.

Re-Call VGA BIOS at S3 Resuming

Selecting Enabled allows BIOS to call VGA BIOS to initialize the VGA card
when system wakes up (resume) from S3 sleep state. The system resume time
is shortened when you disable the function, but system will need an AGP
driver to initialize the VGA card. Therefore, if the AGP driver of the card does
not support the initialization feature, the display may work abnormally or not
function after resuming from S3.

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 A ware 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.

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:

DVI

1) Short for Digital Visual Interface, a digital interface standard created by the Digital
Display Working Group (DDWG) to convert analog signals into digital signals to
accommodate both analog and digital monitors.

supports data transfer rates of up to 400 Mbps for connecting up to 63 external
devices.

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.

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.

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.

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.

PCMCIA

Short forPersonal Computer Memory Card International Association, PCMCIA is an

G-4

organization consisting of some 500 companies that has developed a standard for small
, credit card-sized devices, called PC Cards. Originally designed for adding memory to
portable computers, the PCMCIA standard has been expanded several times and is
now suitable for many types of devices.

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.

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.

SPDIF

Short for Sony/Philips Digital Interface, a standard audio file transfer format. Deverloped
jointly by the Sony and Philips corporations, SPDIF allows the transfer of digital audio
signals from one device to another without having to be converted first to an analog
format.

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.
