2. HARDWARE SETUP
2.1 Getting Started
IMPORTANT: Due to Pentium 4 CPU’s power consumption requirement, an
ATX12V power supply is recommended for this motherboard. For typical system
configurations, anATX12V power supply that can supply at least 230W and at least
8.5A on the +12V lead is required. For heavily-loaded configurations, an ATX12V
power supply that can supply at least 300W is required.
Before using your computer, you must complete the following steps:
• Check Motherboard Settings
• Install Memory Modules
• Install the Central Processing Unit (CPU)
• Install Expansion Cards
• Connect Ribbon Cables, Panel Wires, and Power Supply
WARNING! Computer motherboards and expansion cards contain very delicate
Integrated Circuit (IC) chips. To protect them against damage from static electric-
ity, 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
nothave 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 con-
nectors, or other components.
4. Placecomponentson a grounded antistatic pad oronthebag 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.
WARNING! Make sure that you unplug your power supply when adding or
removing 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. HARDWARE SETUP
2.2 System Memory
NOTE: No hardware or BIOS setup is required after adding or removing memory.
This motherboard has four 184-pin Rambus Inline Memory Modules (RIMM) sockets.
These sockets support 64Mbit, 128Mbit, and 256Mbit Direct RDRAM technologies.
IMPORTANT
1. The memory configuration of channelA(RIMMA1 and RIMMA2) and chan-
nel B (RIMMB1 and RIMMB2) must be identical (see below).
2. C-RIMMs (Continuity RIMM) must be used to complete the sockets that are
not populated by RDRAMs. A C-RIMM is necessary to avoid breaking the
signal lines, which are a serial connection in a Rambus interface, such as
used in this motherboard. This assures the electrical integrity of a Rambus
interface.
3. When C-RIMMs are required, it is recommended that they be inserted into
RIMMA2 and RIMMB2.

2.4 Expansion Cards
WARNING!Unplug your power supply when adding or removing expansion
cards or other system components. Failure to do so may cause severe damage to
both your motherboard and expansion cards (see 3.3 Hardware Setup Proce-
dure for more information).
2.4.1 Expansion Card Installation Procedure
1. Read the documentation for your expansion card and make any necessary hard-
ware or software settings for your expansion card, such as jumpers.
2. Remove your computer system’s cover and the bracket plate on the slot you
intend to use. Keep the bracket for possible future use.
3. Carefully align the card’s connectors and press firmly.
4. Secure the card on the slot with the screw you removed above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary
(such as IRQ xx Used By ISA: Yes in PNPAND PCI SETUP)
7. Install the necessary software drivers for your expansion card.
2.4.2 Assigning IRQs for Expansion Cards
Some expansion cards need an IRQ to operate. Generally, an IRQ must be exclu-
sively assigned to one use. In a standard design, there are 16 IRQs available but
most of them are already in use, leaving 6 IRQs free for expansion cards. If your
motherboard has PCI audio onboard, an additional IRQ will be used. If your moth-
erboard also has MIDI enabled, another IRQ will be used, leaving 4 IRQs free.

2. HARDWARE SETUP
IMPORTANT: If using PCI cards on shared slots, make sure that the drivers sup-
port “Share IRQ” or that the cards do not need IRQ assignments. Conflicts will arise
between the two PCI groups that will make the system unstable or cards inoperable.
2.4.3 Accelerated Graphics Port (AGP) Pro Slot
This motherboard provides an accelerated graphics port (AGP) pro slot to support a
new generation of AGP graphics cards with ultra-high memory bandwidth.

2.5 External Connectors
WARNING! Some pins are used for connectors or power sources. These are
clearly distinguished from jumpers in the Motherboard Layout. Placing jumper
caps over these connector pins will cause damage to your motherboard.
IMPORTANT: Ribbon cables should always be connected with the red stripe to
Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connec-
tor on hard drives and CD-ROM drives, but may be on the opposite side on
floppy disk drives. Check the connectors before installation because there may
be exceptions. IDE ribbon cables must be less than 46 cm (18 in.), with the
second drive connector no more than 15 cm (6 in.) from the first connector.
1) PS/2 Mouse Connector (Green 6-pin PS2MS)
The system will direct IRQ12 to the PS/2 mouse if one is detected. If
one is not detected, expansion cards can use IRQ12. See PS/2 Mouse
Function Control in 4.4 Advanced Menu.
2) PS/2 Keyboard Connector (Purple 6-pin PS2KB)
This connection is for a standard keyboard using an PS/2 plug (mini
DIN). This connector will not allow standard AT size (large DIN)
keyboard plugs. You may use a DIN to mini DIN adapter on stan-
dard AT keyboards.

8) Primary (Blue) / Secondary IDE Connectors (Two 40-1pin IDE)
These connectors support the IDE hard disk ribbon cable. Connect the
cable’s blue connector to the motherboard’s primary (recommended) or
secondary IDE connector, and then connect the gray connector to your
UltraDMA/100 slave device (hard disk drive) and the black connector
to your UltraDMA/100 master device. It is recommended that non-
UltraDMA/100 devices be connected to the secondary IDE connector.
If you install two hard disks, you must configure the second drive to
Slave mode by setting its jumper accordingly. Please refer to your hard
disk documentation for the jumper settings. BIOS now supports specific
device bootup (see 4.6 Boot Menu). (Pin 20 is removed to prevent
inserting in the wrong orientation when using ribbon cables with
pin 20 plugged).
TIP: You may configure two hard disks to be both Masters with two
ribbon cables –one for the primary IDE connector and another for the
secondary IDE connector. You may install one operating system on an
IDE drive and another on a SCSI drive and select the boot disk through
4.6 Boot Menu.
IMPORTANT: UltraDMA/100 IDE devices must use a 40-pin 80-conductor IDE
cable for 100MByte/sec transfer rates.

11)POWER (PWR_FAN), CPU (CPU_FAN), Fan Connectors (3 pins)
These connectors support cooling fans of 350mA (4.2 Watts) or less.
Orientate the fans so that the heat sink fins allow airflow to go across the
onboard heat sink(s) instead of the expansion slots. Depending on the
fan manufacturer, the wiring and plug may be different. The red wire
should be positive, while the black should be ground. Connect the fan’s
plug to the board taking into consideration the polarity of the connector.
NOTE:The “Rotation” signal istobe used onlybyaspecially designed fan
with rotation signal. The Rotations per Minute (RPM) can monitored using
a utility such as HP PC Probe or Intel LDCM.
WARNING! The CPU and/or motherboard will overheat if there is no
airflow across the CPU and onboard heatsinks. Damage may occur to
the motherboard and/or the CPU fan if these pins are incorrectly used.
These are not jumpers, do not place jumper caps over these pins.
