Introducing the Mainboard

Thank you for choosing the L4S5A3 mainboard. This ATX mainboard comes

with the high performance SiS645DX Northbridge and SiS962/SiS962L

Southbridge chipsets. It accommodates Intel Pentium 4 processors, which

supports a frontside bus (FSB) speeds up to 400/533 MHz.

The SiS645DX Northbridge features the AGTL & AGTL+ compliant bus driver

technology with integrated on-die termination to support Intel Pentium 4 series

processors with FSB 100/133 MHz. It can offer bandwidth up to 2.7 GB/s un-

der DDR333 and 1 GB/s under PC133 in order to sustain the bandwidth

demand from host processor, as well as the multi I/O masters and AGP mas-

ters.

The SiS962/SiS962L Southbridge integrates one Universal Serial Bus 2.0

Host Controllers, the 1394a controller (except for SiS962L), audio controller with

AC 97 interface, Ethernet MAC controller with standard MII interface, three

Universal Serial Bus 1.1 Host Controllers and the IDE Master/Slave control-

lers.

The mainboard has an advanced full set of I/O ports, such as dual channel

IDE interfaces, a floppy controller, a high-speed serial port, a VGA port, an

EPP/ECP capable bi-directional parallel port connector, four USB (Universal

Serial Bus) connector, a PS/2 keyboard, mouse and 1394a connectors (except

for SiS962L). One AGP slot, three PCI local bus slots and one communication

and networking riser (CNR) slot provide expandability for add-on peripheral

cards.

Featuring good stability and performance, and the advanced SiS chipset, the

L4S5A3 is an excellent Pentium 4 DDR mainboard for the budget-conscious

consumer. It is the ideal solution for any home or workstation PC.

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 I/O panel

• One cooling fan retention module

• This user’s manual

Processor The mainboard uses a micro PGA 478-pin socket that has the

following features:

• Supports 400/533 MHz frontside bus (FSB)

• Supports “Hyper-Threading” technology CPU

• Accommodates Pentium 4 processors at 1.5G/1.6G/1.7G…

2.5G and above

“Hyper-Threading” technology enables the operating system

into thinking it’s hooked up to two processors, allowing two

threads to be run in parallel, both on separate ‘logical’ proces-

sors within the same physical processor.

Chipset The SiS645DX Northbridge and SiS962/SiS962L Southbridge

chipsets are based on an innovative and scalable architecture

with proven reliability and performance.

• Support Intel Pentium 4 series CPU with data transfer

rate of 400MHz and Over Clocking up to 533MHz

• Support 12 outstanding transactions

• Supports DDR333/266/200 SDRAM or PC133/100

SDRAM

• AGP v2.0 Compliant

• Supports Graphic Window Size from 4MBytes to

256Mbytes

• Perform 533MB/s bandwidth in 66MHz x 4 mode

• Serves Isochronous downstream transfer responsive to

the memory read requests originated from USB or au-

dio/modem controllers

• PCI 2.2 specification compliance

• Supports PIO mode 0,1,2,3,4 and Multiword DMA mode

0,1,2

• Supports Ultra DMA 33/66/100/133

• Three independent OHCI USB 1.1 host controllers and

one EHCI USB 2.0 host controller, support up to six ports

• Compliant with IEEE 1394-1995 and 1394a-2000

• System wake-up events include: Power button, keyboard

password/hot key, RTC alarm, Modem ring-in, LAN, AC

97 wake-up, USB wake up and 1394 wake up

Additional key features of the mainboard include support for

six USB ports, an AC’ 97 link for audio and modem, hardware

monitoring, and ACPI/OnNow power management.

Note: The SiS962L Southbridge chipset does not sup-

port the IEEE1394A function.

Memory The mainboard supports DDR 266/333 SDRAM. It accommo-

dates two unbuffered 2.5V 184-pin slots. Each slot supports up

to 1 GB with a total maximum capacity of 2 GB.

USB 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 s

eed cables can su

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

AGP The mainboard includes a AGP slot that provides four times

the bandwidth of the original AGP specification. AGP technol-

ogy provides a direct connection between the graphics sub-

system and the processor so that the graphics do not have to

compete for processor time with other devices on the PCI bus.

Audio • Compliant with AC'97 Codec

• 4 stereo analog inputs with 5-bits volume controls for

each channel

• Input mixer for 4 stereo, MIC and DAC inputs

• Advanced Power Management

• Two PS/2 ports for mouse and keyboard

• One serial port

• One parallel port

• Four USB ports

• One LAN port

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

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.

Some hardware specifications and software items are subject to change

without prior notice.

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

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

mainboard are implemented by cabling connectors on the mainboard to indi-

cators and switches on the system case. Ensure that your case supports all

the features required. The mainboard can support one or two floppy diskette

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 an ATX form factor of 305 x 220 mm. Choose a case that

accommodates this form factor.
