3.4.2 Memory Installation
WARNING! Make sure that you unplug your power supply when adding or
removing memory modules or other system components. Failure to do so may
cause severe damage to both your motherboard and expansion cards (see 3.3
Hardware Setup Procedure for more information).
Insert the module(s) as shown. Because the number of pins are different on either
side of the breaks, the module will only fit in the orientation shown. DRAM SIMM
modules have the same pin contacts on both sides. SDRAM DIMMs have different
pin contacts on each side and therefore have a higher pin density.
88 Pin
60 Pin
P4B-LA
20 Pin
P4B-LA 168-Pin DIMM Sockets
The DIMMs must be 3.3Volt unbuffered SDRAMs. To determine the DIMM type,
check the notches on the DIMMs (see figure below).
The notches on the DIMM will shift between left, center, or right to identify the type
and also to prevent the wrong type from being inserted into the DIMM slot on the
motherboard. You must tell your retailer the correct DIMM type before purchasing.
This motherboard supports four clock signals per DIMM.

the CPU into the socket to avoid bending the
pins. If the CPU does not fit, check its
alignment and look for bent pins.
3. Once completely inserted, press the CPU firmly and close the socket lever until it
snaps into its locked position.
4. Install an Intel fan heatsink.
CAUTION! Take care not to scrape the motherboard surface when mounting a
clamp-style processor fan, or else damage may occur. When mounting a heatsink
onto your CPU, make sure that exposed CPU capacitors do not touch the
heatsink, or else damage may occur! Refer to heatsink/CPU documentation.

3. HARDWARE SETUP
3.6 Installing the Heatsink and Fan
The Intel® Pentium® 4 478/Northwood Processor requires a specially designed
heatsink and fan assembly to ensure optimum thermal condition and performance.
The Intel Pentium 4 478/Northwood Processor includes the heatsink, fan, and retention mechanism. In case you buy a CPU separately, make sure that you use only
Intel certified heatsink and fan.
Step 1: Mount the Heatsink:
1. Place the heatsink on top of the installed CPU, making sure that the heatsink fits
properly on the retention module base. Note that the retention module base is
already installed on the motherboard.

P4B-LA Quick Start Manual
3. HARDWARE SETUP
3.7.2 Assigning IRQs for Expansion Cards
Some expansion cards need an IRQ to operate. Generally, an IRQ must be assigned
exclusively 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 the motherboard
has PCI audio onboard, an additional IRQ will be used. If the motherboard also has
MIDI enabled, another IRQ will be used, leaving 4 IRQs free.

3.8 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 connector 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 cable must be less than 46 cm (18 in.), with the second drive connector no more than 15 cm (6 in.) from the first connector.
3. H/W SETUP
Connectors
1) PS/2 Mouse Connector (Green 6-pin PS2KBMS)
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.
PS/2 Mouse (6-pin female)
2) PS/2 Keyboard Connector (Purple 6-pin PS2KBMS)
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 standard AT keyboards.

9) Primary (Blue) / Secondary IDE Connectors (40-1 pin IDE1/IDE2)
These connectors support the provided UltraDMA/66 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/66 slave device (hard disk drive) and the black connector
to your UltraDMA/66 master device. It is recommended that non-UltraDMA/66
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. Refer to your hard disk documentation for the jumper
settings. BIOS now supports specific device bootup (See BIOS). (Pin 20 is removed to prevent inserting in the wrong orientation when using ribbon cables
with pin 20 plugged). If you have more than two UltraDMA/66 devices, you
will need to purchase another UltraDMA/66 cable.
NOTE: The hole near the blue connector on the UltraDMA/66 cable is intentional.
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 BIOS.
NOTE: Orient the red markings
(usually zigzag) on the IDE
ribbon cable to PIN 1.

10) CPU (CPU_FAN), Power Supply (PS_FAN), Chassis (SYS_FAN) Fan
Connectors (3 pins)
These connectors support cooling fans of 750mA or less. Orient 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 is to be used only by a specially designed fan with
rotation signal.

Connectors
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.
