Introducing the Mainboard

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.

Compare the mainboard’s package contents with the following checklist:

Standard Items

•One mainboard

•One diskette drive ribbon cable

•One IDE drive ribbon cable

•One auto-install software support CD

•One 1394 bracket (optional)

•This user’s manual

Processor The mainboard uses an AMD 462-pin Socket A that has the

following features:

•Supports 200/266 MHz frontside bus (FSB)

•Accommodates AMD Athlon Duron, Athlon, and Athlon XP

processors.

The SiS740 Northbridge and SiS961 Southbridge chipsets are

based on an innovative and scalable architecture with proven

reliability and performance. A few of the chipset’s advanced

features are:

•Integrated DRAM controller supports memory bus up to

266 MHz

•A 16-bit bi-directional data bus provides high I/O throughput

•Integrated 2D/3D accelerator providing high graphics

performance

•A low 2.5-volt DDR266 SDRAM power consumption

which makes it an excellent solution for notebooks and

desktops with a small footprint

•Built in GDI+ accelerator

•An ATA 100 interface on the chipset, which helps boost

system performance by providing a high-speed connec-

tion to ATA 100 Hard Disk Drives, delivering maximum

sustained data transfer rates of 100 MB/sec

Additional key features include support for six USB ports, an

AC 97 link for audio and modem, hardware monitoring, and

ACPI/OnNow power management.

Chipset

This mainboard may support either one of the three

Southbridge chipset. Refer below for details:

•SiS961 Southbridge –supports ATA100 interface and

six USB ports.

•SiS961B Southbridge –supports ATA133 interface and

six USB ports.

•SiS962 Southbridge –supports ATA133 interface and

six USB ports including onboard USB 2.0 and IEEE

1394A controller.

USB USB 1.1

The SiS961 or SiS961B Southbridge chipset features the USB

1.1 specification which can support for six USB ports.

However, if the mainboard comes with SiS962 Southbridge

chipset, then the mainboard supports the USB 2.0 specifica-

tion.

USB 2.0 (optional)

The USB 2.0 Controller is compliant with Universal Serial Bus

Specification Revision 2.0.

The USB 2.0 supports data transfer rates up to 480MB/sec for

high-speed devices and specifies a microframe that will be

1/8th of a 1msec frame. This allows the USB 2.0 devices to

have small buffers even at high data rates.

The USB 1.1 connectors and other full speed cables can sup-

port the higher speed of USB 2.0 without any changes.

The chipset has the following advanced USB features:

•Compliant with Enhanced Host Controller Interface

(EHCI) Specification Revision 0.95 and Universal Host

Controller Interface (UHCI) Specification Revision 1.1

•PCI multi-function device consists of two UHCI Host Control-

lers for full/low-speed signaling and one EHCI Host

•Controller core for high-speed signaling

•Supports PCI-Bus Power Management Interface Specifi-

cation release 1.1

•Legacy support for all downstream facing ports

IEEE 1394A Con-

troller Interface

(optional)

•Fully supports provisions of IEEE 1394-1995 and P1394A

for high performance serial bus

•Provides two fully compliant cable ports at 100/200/400

Mbits and operates in one, two or three port mode

•Single 24.576 MHZ crystal provide transmit/receive data

at 100/200/400 Mbits/s and LLC clock at 49.152 M

•Separate cable bias (TPBIAS) and driver termination

voltage supply for each port

•Support power-down feature to conserve energy in bat-

tery powered applications

Memory The mainboard accommodates DDR200/266 DDR SDRAM (Dou-

ble Data Rate Synchronous DRAM) up to 2 GB using two 2.5V

unbuffered DIMM modules.

AC 97 Audio

Codec The AC 97 Audio codec is compliant with the AC 97 2.2 speci-

fication, and supports 18-bit ADC (Analog Digital Converter)

and DAC (Digital Analog Converter) resolution as well as 18-bit

stereo full-duplex codec with independent and variable sam-

pling rates. Further features include support for six analogline-

level stereo inputs.

Expansion

Options The mainboard comes with the following expansion options:

•Three 32-bit PCI slots

•A Communications Network Riser (CNR) slot

•Two IDE connectors which support four IDE channels and

a floppy disk drive interface

The L7SOM supports Ultra DMA bus mastering with transfer

rates of 33/66/100 MB/sec.

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.

Integrated I/O The mainboard has a full set of I/O ports and connectors:

•Two PS/2 ports for mouse and keyboard

•One serial port

•One VGA port

•One parallel port

•One MIDI/game port

•One LAN port

•Two USB ports

•Audio jacks for microphone, line-in and line-out

Onboard LAN

(optional) The Realtek RTL8100 LAN chip is incorporated in the chipset

providing the mainboard with integrated Ethernet PCI LAN

capabilities.

VGA The mainboard has a built-in high performance, quality 2D/3D

graphics accelerator. The graphics system supports the Ultra-

AGP II ™ with 2GB/s bandwidth architecture and uses a

shared memory scheme that allows up to 64MB of system

memory to be used as video memory.

BIOS

Firmware This mainboard uses Award BIOS that enables users to con-

figure many system features including the following:

•Power management

•Wake-up alarms

•CPU parameters

•CPU and memory timing

The firmware can also be used to set parameters for different

processor clock speeds.

There are many types of computer cases on the market. The mainboard com-

plies with the specifications for the Micro ATX system case. Some features on

the mainboard are implemented by cabling connectors on the mainboard to

indicators and switches on the system case. Ensure that your case supports

all the features required. The mainboard can support one or two floppy disk-

ette drives and four enhanced IDE drives. Ensure that your case has sufficient

power and space for all the drives that you intend to install.

Most cases have a choice of I/O templates in the rear panel. Make sure that

the I/O template in the case matches the I/O ports installed on the rear edge

of the mainboard.

This mainboard has a Micro ATX form factor of244 mm x 244 mm. Choose a

case that accommodates this form factor.
