Introducing the Mainboard

Thank you for choosing the L4S8A2 mainboard. The L4S8A2 mainboard is a

high–performance, enhanced function mainboard that supports Socket 478

Pentium 4 processors with system speeds up to 533MHz for high-end

business or personal desktop markets.

The mainboard incorporates the SiS648 Northbridge and SiS963 Southbridge

chipsets. The SiS648 Northbridge chipset provides a 12-level In-Order-Queue

to support maximum outstanding transactions on host up to 12. The memory

controller offers high-bandwidth up to 2.7GB/s under DDR333 in order to

sustain the bandwidth demand from the host processor, as well as the multi

I/O masters and AGP masters. While the SiS963 Southbridge integrates the

Universal Serial Bus 2.0 Host Controllers, 1394a and Audio Controller with AC

97 interface.

The L4S8A2 is designed to give customers an advanced, multimedia solution

at a very low cost. It is equipped with advanced full set of I/O ports, such as

dual channel IDE interfaces, a floppy controller, two high-speed serial port, an

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

Serial Bus) connector, a PS/2 keyboard and mouse connectors. One AGP slot,

five PCI local bus slots and one communication and networking riser (CNR -

optional) slot provide expandability for add-on peripheral cards.

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

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 (optional)

• 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 L4S8A2 mainboard uses a micro PGA 478-pin socket that

has the following features:

• Supports 400/533 MHz system bus

• 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’

processors within the same physical processor.

Chipset The SiS648 and SiS963 chipsets are based on an innovative

and scalable architecture with proven reliability and

performance. A few of the chipset’s advanced features are:

• Supports Intel Pentium 4 series CPU with data transfer

rate up to 533MHz

• Support 12 outstanding transactions and out-of-order

completion

• Supports 64-bit high performance DDR333/DDR266

Memory Controller

• Universal AGP v3.0 compliant and supports AGP 8X/4X

Interface with Fast Write Transaction

• Distributed arbitration strategy with long contiguous data

streaming up to 1GB/s

• PCI 2.2 specification compliance

• Integrated multi-threaded I/O link mastering with read

pipelined streaming

• Supports Ultra DMA 33/66/100/133

Additional key features include support for six USB 2.0 ports,

Fast Ethernet MAC controller, AC97 interface, advanced

power management, integrated DMA controller and keyboard

controller.

Memory • Supports DDR SDRAM up to 200/266/333 MHz memory

module

• Accommodates three unbuffered 2.5V 184-pin slots

• Each slot supports up to 1 GB with a total maximum

capacity of 3 GB

AGP The L4S8A2 includes an 8xAGP slot that provides eight times

the bandwidth of the original AGP specification. The AGP 3.0

(8xAGP) offers a significant increase in performance along

with feature enhancements to AGP2.0. This interface

represents the natural evolution from the existing AGP to meet

the ever-increasing demands placed on the graphic interfaces

within the workstation and desktop environments.

AC’ 97 Audio

Codec The AC’ 97 Audio codec is compliant with the AC’ 97 2.2

specification, 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 sampling rates. Further features include support for

four analog line-level stereo inputs.

Expansion

Options The mainboard comes with the following expansion options:

• Five 32-bit PCI slots

• One 8x/4x AGP slot

• A Communications Network Riser (CNR) slot (AC97

interface only) (optional)

• Two IDE connectors which support four IDE channels and

a floppy disk drive interface

The L4S8A2 supports Ultra DMA bus mastering with transfer

rates of 33/66/100/133 MB/sec.

Onboard LAN

(optional) RTL8201BL is a Fast Ethernet Phyceiver with an MII (Media

Independent Interface)/SNI (Serial Network Interface). It can

be used as a Network Interface Adapter, MAU, CNR, ACR,

Ethernet Hub, and Ethernet Switch.

It is incorporated in the chipset providing the mainboard with

10/100Mbps fast Ethernet controller and integrated Ethernet

PCI LAN capabilities.

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

• Two PS/2 ports for mouse and keyboard

• Two serial port (COM2 – optional)

• One parallel port

• Four USB ports

• One LAN port (optional)

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

BIOS

Firmware This mainboard uses Award BIOS that enables users to

configure 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

complies with the specifications for the 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

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 190 mm. Choose a case that

accommodates this form factor.
