Processor The L4S5A mainboard uses a micro PGA 478-pin socket that
has the following features:
•
Supports 400 MHz frontside bus (FSB)
•
Accommodates Pentium 4 processors
Chipset The SiS645 and SiS961 chipsets are based on an innovative
and scalable architecture with proven reliability and perform-
ance. A few of the chipset's advanced features are:
•
A low 2.5-volt DDR SDRAM power consumption which
makes it an excellent solution for notebooks and desktops
with a small footprint
•
Support for a 4xAGP interface providing vivid 3D graphics
and video performance
•
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
•
Built-in multithreaded I/O link used to enhance perform-
ance, providing enough I/O bandwidth for throughput up
to 1.2 GB/s
Additional key features include support for six USB ports, an
AC 97 link for audio and modem, hardware monitoring, and
ACPI/OnNow power management.
Memory The mainboard supports DDR up to 333/266 MHz SDRAM. It
accommodates three unbuffered 2.5V 184-pin slots. Each slot
supports up to 1 GB with a total maximum capacity of 2 GB.
VGA The L4S5A includes a 4xAGP slot that provides four times the
bandwidth of the original AGP specification. AGP technology
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.
AC' 97 Audio The AC' 97 Audio codec is compliant with the AC' 97 2.2
Codec
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 The mainboard comes with the following expansion options:
Options •
Six 32-bit PCI slots (PCI 6 and onboard LAN share)
•
One 4xAGP 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
The L4S5A supports Ultra DMA bus mastering with transfer
rates of 33/66/100 MB/sec.
