Processor
The L4S8A mainboard uses a micro PGA 478-pin socket that
has the follow ing features:
•
Supports 400/533 MHz system bus
•
Accommodates Pentium 4 processors at 1.5G/1.6G/1.7G…
2.5G and above
Chipset
The SiS648 and SiS963 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 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
•
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 ports, Fast
Ethernet MAC controller, AC97 interface, IEEE 1394A host
controller, advanced power management, integrated DMA
controller and keyboard controller.
Memory
•
Supports DDR up to 200/266/333 MHz SDRAM 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 L4S8A 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 repre-
sents 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
specification, and supports 18-bit ADC (Analog Digital Con-
verter) and DAC (Digital Analog Converter) resolution as well
as 18-bit stereo full-duplex codec with independent and vari-
able 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 (PCI 5 and onboard RAID share)
•
One 8X/4X AGP slot
•
A Communications Network Riser (CNR) slot (AC97 inter-
face only)
•
Two IDE connectors which support four IDE channels and
a floppy disk drive interface
