Introducing the Mainboard
I
In nt tr ro od du uc ct ti io on n
Congratulations on purchasing the L7SOM mainboard. The L7SOM main-
board is an Micro ATX mainboard that uses a 4-layer printed circuit board and
measures 244 mm x 244 mm. The mainboard features a Socket 462 that ac-
commodates AMD Athlon processors supporting frontside bus (FSB) speeds
up to 266 MHz.
The L7SOM incorporates the SiS740 Northbridge and SiS961 (or SiS961B
/SIS962) Southbridge chipsets which combine support for the new high-
bandwidth Double Data Rate (DDR) 266 SDRAM, 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 2.1 GBps by transferring
data on both the rising 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 the mainboard
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
automatic 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
rated speed.

13
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 462 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.
CPU Installation Procedure
The following illustration shows CPU installation components:
Note: The pin A-1 corner on the CPU and socket is empty.
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 A-1 on the CPU
socket (the corner with the pinhole noticeably missing). Insert the processor
into the socket. Do not use force.
3. Swing the locking lever down and hook it under the latch on the edge of the
socket.
4. Apply thermal grease to the top of the CPU.
5. Lower the CPU cooling fan/heatsink assembly onto the CPU

14
6. Secure the two retention clips
on either side of the
fan/heatsink unit onto the
Socket 462 base.

7. Connect the CPU Cooling Fan
power cable connector to the
CPUFAN connector.
Note:CPU fan and heatsink installation procedures may vary with the type of
CPU fan/heatsink supplied. The form and size of fan/heatsink may also
vary.

15
Installing Memory Modules
This mainboard accommodates 184-pin 2.5V unbuffered Double Data Rate
(DDR) SDRAM 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.
Installation Procedure
The mainboard accommodates two
memory modules.
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 and 2.1 GBps. DDR
SDRAM uses additional power and
ground lines and requires 184-pin
DIMM modules rather than the 168-
pin DIMMs used by SDRAM.
Refer to the following to install the memory modules.
1. Push the latches on each side of the DIMM slot down.
5. 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
installed correctly.
6. Check that the cutouts onthe
DIMM module edge connector
match the notches in the
DIMM slot:
7. 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.
8. 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.
Note: If the mainboard incorporates the SiS961B or SiS962 Southbridge chipset,
the Ultra DMA bus mastering can support up to 133 MB/sec transfer rate.
For SiS961 Southbridge chipset, the transfer rate can support up to
100MB/sec only.
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).
