Introducing the Mainboard
I
In nt tr ro od du uc ct ti io on n
Congratulations on purchasing the L4S5MG/GL mainboard. The L4S5MG/GL
mainboard is a Micro ATX mainboard that uses a 4-layer printed circuit board
and measures 244 mm x 220 mm. The mainboard features a mPGA Socket
478 that accommodates Pentium 4 processors supporting data transfers up to
400 MHz.
The L4S5MG/GL incorporates the XP4GL chipset which combines support for
the new high-bandwidth Double Data Rate (DDR) 266/333 SDRAM, Inte-
grated VGA and the AC 97 audio codec.
Note: SDRAM provides 800 MBps or 1 GBps data transfer depending on whether
the bus is 100 MHz or 133 MHz. Double Data Rate SDRAM (DDR SDRAM)
doubles the rate to 1.6 GBps or 2.7 GBps by transferring data on both the ris-
ing and falling edges of the clock. DDR SDRAM uses additional power and
ground lines and requires 184-pin DIMM modules rather than the 168-pin
DIMMs used by SDRAM.

Installing the Processor
Caution: When installing a CPU heatsink and cooling fan make sure that
you DO NOT scratch the mainboard or any of the surface-mount resistors
with the clip of the cooling fan. If the clip of the cooling fan scrapes
across the mainboard, you may cause serious damage to themainboard
or its components.
On most mainboards, there are small surface-mount resistors near the
processor socket, which may be damaged if the cooling fan is carelessly
installed.
Avoid using cooling fans with sharp edges on the fan casing and the
clips. Also, install the cooling fan in a well-lit work area so that you can
clearly see the mainboard and processor socket.
Before installing the Processor
This mainboard automatically determines the CPU clock frequency and sys-
tem bus frequency for the processor. You may be able to change these
settings by making changes to jumpers on the mainboard, or changing the
settings in the system Setup Utility. We strongly recommend that you do not
overclock processors or other components to run faster than their ratedspeed.
Warning: Overclocking components can adversely affect the reliability of
the system and introduce errors into your system. Overclocking can per-
manently damage the mainboard by generating excess heat in
components that are run beyond the rated limits.
This mainboard has a Socket 478 processor socket. When choosing a proc-
essor, consider the performance requirements of the system. Performance is
based on the processor design, the clock speed and system bus frequency of
the processor, and the quantity of internal cache memory and external cache
memory.

12
CPU Installation Procedure

Note: The pin-1 corner is marked with an arrow
Follow these instructions to install the CPU:
1. Pull the CPU socket locking lever away from the socket to unhook it and raise
the locking lever to the upright position.
2. Match the corner on the
CPU marked with an arrow
with pin-1 on the CPU
socket (the corner with the
pinhole noticeably missing).
Insert the processor into the
socket. Do not use force.
3. Lower the heatsink over the CPU.
4. Lower the CPU cooling fan onto the heatsink.
5. Apply thermal grease to the top of the CPU.

CPU fan/heatsink supplied. The form and size of fan/heatsink may also
vary.

14
Installing Memory Modules
This mainboard accommodates 184-pin 2.5V unbuffered Double Data Rate
(DDR) SDRAM memory modules. The memory chips must be standard or
registered SDRAM (Synchronous Dynamic Random Access Memory). The
memory bus runs at 166 MHz.
The mainboard accommodates two memory modules. You must install at least
one module in any of the two slots. Each module can be installed with 32 MB
to 1 GB of memory; total memory capacity is 2 GB.
Do not remove any memory module from its antistatic packaging until
you are ready to install it on the mainboard. Handle the modules only by
their edges. Do not touch the components or metal parts. Always wear
a grounding strap when you handle the modules.
Installation Procedure
Refer to the following to install the memory modules.
1. This mainboard supports unbuffered DDR SDRAM only. Do not attempt to
insert any other type of DDR SDRAM into the slots.
2. Push the latches on each side of the DIMM slot down.
3. Align the memory module with
the slot. The DIMM slots are
keyed with notches and the
DIMMs are keyed with cutouts
so that they can only be in-
stalled correctly.
4. Check that the cutouts on the
DIMM module edge connector
match the notches in the
DIMM slot.
5. Install the DIMM module into
the slot and press it firmly
down until it seats correctly.
The slot latches are levered
upwards and latch on to the
edges of the DIMM.
6. Install any remaining DIMM modules.

Installing a Hard Disk Drive/CD-ROM
This section describes how to install IDE devices such as a hard disk drive
and a CD-ROM drive.
About IDE Devices
Your mainboard has a primary and secondary IDE channel interface (IDE1 and
IDE2). An IDE ribbon cable supporting two IDE devices is bundled with the main-
board.
If you want to install more than two IDE devices, get a second IDE cable and
you can add two more devices to the secondary IDE channel.
IDE devices have jumpers or switches that are used to set the IDE device as
MASTER or SLAVE. Refer to the IDE device user’s manual. When installing two
IDE devices on one cable, ensure that one device is set to MASTER and the
other device is set to SLAVE. The documentation of your IDE device explains
how to do this.
About UltraDMA
This mainboard supports UltraDMA 66/100. UDMA is a technology that accel-
erates the performance of devices in the IDE channel. To maximize
performance, install IDE devices that support UDMA and use 80-pin IDE ca-
bles that support UDMA 66/100.
Installing a Hard Disk Drive
1. Install the hard disk drive into the drive cage in your system case.
2. Plug the IDE cable into IDE1
(A):
Note: Ribbon cable connectors
are usually keyed so that they can
only be installed correctly on the
device connector. If the connector
is not keyed, make sure that you
match the pin-1 side of the cable
connector with the pin-1 side of the
device connector. Each connector
has the pin-1 side clearly marked.
The pin-1 side of each ribbon ca-
ble is always marked with a
colored stripe on the cable.
3. Plug an IDE cable connector into the hard disk drive IDE connector (B). It
doesn't matter which connector on the cable you use.
4. Plug a power cable from the case power supply into the power connector on
the hard disk drive (C).
When you first start up your system, the BIOS should automatically detect
your hard disk drive. If it doesn’t, enter the Setup Utility and use the IDE Hard
Disk Auto Detect feature to configure the hard disk drive that you have in-
stalled. SeeIDE HDD Auto-Detection on page28 for more information.

16
Installing a CD-ROM/DVD Drive
1. Install the CD-ROM/DVD drive into the drive cage in your system case.
2. Plug the IDE cable into IDE1
(A). If you have already installed
an HDD, use the other connec-
tor on the IDE cable.
Note: Ribbon cable connectors are
usually keyed so that they can only
be installed correctly on the device
connector. If the connector is not
keyed, make sure that you match the
pin-1 side of the cable connector with
the pin-1 side of the device connec-
tor. Each connector has the pin-1
side clearly marked. The pin-1 side of
each ribbon cable is always marked
with a colored stripe on the cable.
3. Plug an IDE cable connector into the CD-ROM/DVD drive IDE connector (B). It
doesn't matter which connector on the cable you use.
4. Plug a power cable from the case power supply into the power connector on
the CD-ROM/DVD drive (C).
5. Use the audio cable provided with the CD-ROM/DVD drive to connect to the
mainboard CD-in connector CDIN1 or CDIN2 (D).
When you first start up your system, the BIOS should automatically detect
your CD-ROM/DVD drive. If it doesn’t, enter the Setup Utility and configure
the CD-ROM/DVD drive that you have installed. See IDE Primary/Secondary
Master/Slave (Auto) on page28 for more information.
Installing a Floppy Diskette Drive
The mainboard has a floppy diskette drive (FDD) interface and ships with a
diskette drive ribbon cable that supports one or two floppy diskette drives. You
can install a 5.25-inch drive and a 3.5-inch drive with various capacities. The
floppy diskette drive cable has one type ofconnector for a 5.25-inch drive and
another type of connector for a 3.5-inch drive.
1. Install the FDD into the drive cage in your system case.
2. Plug the FDD cable into
FLOPPY1 (A):
Note: Ribbon cable connectors are
usually keyed so that they can only
be installed correctly on the device
connector. If the connector is not
keyed, make sure that you match the
pin-1 side of the cable connector with
the pin-1 side of the device connec-
tor. Each connector has the pin-1
side clearly marked. The pin-1 side of
each ribbon cable is always marked
