Introducing the Mainboard

Thank you for choosing 748-A mainboard. The 748-A is designed to fit the

advanced AMD processors in the 462-pin package. Based on the ATX form

factor featuring the SiS748 Northbridge and SiS963L Southbridge chipsets.

The mainboard incorporates the SiS748 Northbridge and SiS963L

Southbridge chipsets. The SiS748 Northbridge features an AGP 8X bridge

and a DDR-400 Memory controller, supporting AMD Athlon S2K FSB up to

400 MHz. While the 963L Southbridge integrates the Universal Serial Bus 2.0

Host Controllers and Audio Controller withAC 97 interface.

The 748-A is designed to give customers a high quality, multimedia solution

and state-of-the-art technology. It provides advanced set of I/O ports, such as

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

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

Serial Bus) connector, a PS/2 keyboard connector, mouse connector and au-

dio jacks for microphone, line-in and line-out. One AGP slot and five PCI local

bus slots provide expandability for add-on peripheral cards.

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

• This user’s manual

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

400 MHz frontside bus (FSB).

Chipset The SiS748 and SiS963L chipsets are based on an innovative

and scalable architecture with proven reliability and perform-

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

• Supports AMD AthlonXP CPU up to 400 MHz FSB

• Supports Synchronous/Quasi-synchronous Host to

DRAM Timing

• Supports 266/333/400 DDR SDRAM

• Sustains DDR SDRAM CAS Latency at options of 2, 2.5,

& 3 clocks.

• AGP v3.0 Compliant

• Supports AGP 8X/4X Interface

• Bi-directional 16 bit data bus

• 1 GB/s performance in 133MHz x 4 mode

• PCI 2.2 Specification Compliance

• Integrated Multithreaded I/O Link Mastering with Read

Pipelined Streaming

• Supports Enhanced Software and Automatic schemes to

access PHY registers

• Supports Ultra DMA 33/66/100/133

• USB v2.0 and Enhanced Host Controller Interface (EHCI)

v1.0 compatible

Additional key features include support for six USB ports, Fast

Ethernet MAC controller, AC97 interface, advanced power

management, integrated DMA controller and keyboard control-

ler.

Memory • Supports DDR up to 266/333/400 MHz SDRAM memory

module

• Accommodates three unbuffered 2.5V 184-pin slots

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

pacity of 3 GB

Graphics The 748-A includes an AGP slot that provides eight times the

bandwidth of the original AGP specification. The AGP 3.0 (8x

AGP) 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.

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

fication that meets the PC2001 requirements and supports

S/PDIF Out. It also has a built-in buffer and internal PLL. Fea-

tures include support for analog switch for rear-out (share), the

line-in jack (share), center/bass (share), and MIC jack to output

6 channels audio.

Expansion

Options The mainboard comes with the following expansion options:

• Five 32-bit PCI slots

• One AGP slot (supports 1.5V AGP Interface only)

• A Communications Network Riser (CNR) slot (AC97 inter-

face only)

• Two IDE connectors which support four IDE channels and

a floppy disk drive interface

The 748-A supports Ultra DMA bus mastering with transfer

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

Onboard LAN

(optional) The VT6103L is a Physical Layer device for Ethernet 10BASE-

T and 100BASE-TX using category 5 Unshielded, Type 1

Shielded, and Fiber Optic cables.

• Dual Speed – 100/10 Mbps

• Half And Full Duplex

• Meet All Applicable IEEE 802.3, 10Base-T and 100Base-

Tx Standards

• Adaptive Equalizer

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 ports (COM2 is optional)

• One parallel port

• Four USB ports

• One LAN port

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

BIOS

Firmware This mainboard uses AMI BIOS that enables users to config-

ure 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 190 mm. Choose a case that

accommodates this form factor.
