2.4 Motherboard Settings

This section explains in detail how to change your motherboard’s function settings
through the use of switches and/or jumpers.

WARNING! Computer motherboards and expansion cards contain very delicate

Integrated Circuit (IC) chips. To protect them against damage from static electric­ity, you should follow some precautions whenever you work on your computer.

1. Unplug your computer when working on the inside.

2. Use a grounded wrist strap before handling computer components. If you do
not have one, touch both of your hands to a safely grounded object or to a
metal object, such as the power supply case.

3. Hold components by the edges and try not to touch the IC chips, leads or
connectors, or other components.

Motherboard Settings

2. H/W SETUP

4. Place components on a grounded antistatic pad or on the bag that came with
the component whenever the components are separated from the system.

5. Ensure that the ATX power supply is switched off before you plug in or
remove the ATX power connector on the motherboard.

2. HARDWARE SETUP

WARNING! Make sure that you unplug your power supply when adding or re-

moving system components. Failure to do so may cause severe damage to your
motherboard, peripherals, and/or components. The onboard LED when lit acts as
a reminder that the system is in suspend or soft-off mode and not powered OFF.

2.5 System Memory (DDR DIMM)

This motherboard uses only Double Data Rate (DDR) Dual Inline Memory Modules
(DIMMs). Two sockets are available for 2.5Volt (power level) unbuffered/registered
Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM)
of 64MB, 128MB, 256MB, 512MB, 1GB to form a memory size between 64MB to
2GB. One side (with memory chips) of the DIMM takes up one row on the motherboard.

DDR DIMMs support both ECC (Error Correction Code, typically used in servers)
and non-ECC (used on desktops/laptops) and are available in both registered (typi­cally used in servers) and unbuffered (typically used in PCs) versions.

NOTE: The DDR memory bus runs at the same frequency as the CPU front side bus.

Install memory in any combination as follows:

DIMM Location 184-pin DIMM Total Memory

Socket 1 (Rows 0&1) 64MB, 128MB, 256MB, 512MB, 1GB x1
Socket 2 (Rows 2&3) 64MB, 128MB, 256MB, 512MB, 1GB x1

2.5.1 General DIMM Notes

• DIMMs that have more than 18 chips are not supported on this motherboard.

• For the system CPU bus to operate at 200MHz/266MHz, use only PC1600-/

PC2100-compliant DIMMs.

• motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of
choice for best performance vs. stability.

• BIOS shows SDRAM memory on bootup screen.

• Single-sided DDR DIMMs come in 64, 128, and 256MB; double-sided come in

128, 256, and 512MB.

WARNING! Be sure that the DIMMs you use can handle the specified DDR

SDRAM MHz or else bootup will not be possible.

2.6 Central Processing Unit (CPU)

The motherboard provides a Socket 462 or Socket A for CPU installation. The CPU
that came with the motherboard should have a fan and heatsink attached to it to
prevent overheating. If this is not the case, then purchase and install a set before you

turn on your system.

W ARNING! Make sure that the heatsink is mounted tightly against the processor .

Make sure also that there is sufficient air circulation across the processor’s heat­sink by regularly checking that your CPU fan is working. Without sufficient cir­culation, the processor could overheat and damage both the processor and the

motherboard. You may install an auxiliary fan, if necessary.

To install a CPU, first turn off your system and remove its cover . Locate the Socket
462 and open it by first pulling the lever sideways away from the socket, then up­wards. The socket lever must be fully opened (90 to 100 degrees) when installing or
removing the CPU. Insert the CPU with the correct orientation. The notched corner
should be oriented toward the blank space on the socket nearest the lever . The CPU
has a corner pin for two of the four corners, and will only fit in the orientation as
shown. Ensure that the CPU is exactly parallel to the socket base so the pins make
good contact and are not bent. Take care not to exert too much force, but press the
CPU down gently into the slot. Once completely inserted, close the socket lever
while holding down the CPU. Make sure the CPU fan and heatsink cover the entire
face of the CPU. W ith the added weight of the CPU fan and heatsink locking brace,
no extra force is required to keep the CPU in place.

CPU

2. H/W SETUP

NOTE: If the CPU does not drop into the socket with minimal pressure, check the
CPU for bent pins or reorient the CPU.

CAUTION! Be careful not to scrape the motherboard when mounting/unmounting

a clamp-style processor fan or else damage may occur to the motherboard.

BERMUDA System Panel Connectors

This 3-1 pin connector connects to the system power LED, which lights when
the system is powered on and blinks when it is in sleep or soft-off mode.

This 4-pin connector connects to the case-mounted speaker.

20) System Message LED Lead (2-pin MSGLED)

This indicates whether a message has been received from a fax/modem. The
LED will remain lit when there is no signal and blink when there is data re­ceived. This function requires an ACPI OS and driver support.

21) System Management Interrupt Lead (2-pin SMI)

This allows the user to manually place the system into a suspend mode or “Green”
mode where system activity will be instantly decreased to save electricity and
expand the life of certain components when the system is not in use. This 2-pin
connector (see the preceding figure) connects to the case-mounted suspend switch.

22) ATX Power Switch / Soft-Off Switch Lead (2-pin PWR)

The system power is controlled by a momentary switch connected to this lead.
Pushing the button once will switch the system between ON and SLEEP or ON
and SOFT OFF, depending on your BIOS or OS setting. Pushing the switch
while in the ON mode for more than 4 seconds will turn the system off. The
system power LED shows the status of the system’s power.

23) Reset Switch Lead (2-pin RST)

This 2-pin connector connects to the case-mounted reset switch for rebooting
your computer without having to turn off your power switch. This is a preferred
method of rebooting to prolong the life of the system’s power supply.

A Note about Passwords

The BIOS Setup program allows you to specify passwords in the Main menu. The pass­words control access to the BIOS during system startup. The passwords are not case sen­sitive. In other words, it makes no difference whether you enter a password using upper or
lowercase letters. The BIOS Setup program allows you to specify two separate passwords:

a Supervisor password and a User password. When disabled, anyone may access all BIOS
Setup program functions. When enabled, the Supervisor password is required for entering
the BIOS Setup program and having full access to all configuration fields.

Forgot the Password?

If you forgot the password, you can clear the password by erasing the CMOS Real Time
Clock (R TC) RAM. The RAM data containing the password information is powered by the
onboard button cell battery. To erase the R TC RAM: (1) Unplug your computer, (2) Short
the solder points, (3) T urn ON your computer , (4) Hold down <Delete> during bootup and
enter BIOS setup to re-enter user preferences.
