Processor The L4S5M mainboard uses a micro PGA 478-pin socket that
has the following features:
•
Supports 100 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
performance. 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 connection 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 performance,
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 SDRAM. It accommodates two
unbuffered 2.5V 184-pin slots. Each slot supports up to 1 GB
with a total maximum capacity of 2 GB.
VGA The L4S5M 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
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 The mainboard comes with the following expansion options:
•
Options
Three 32-bit PCI slots
•
One 4xAGP slot
•
A Communications Network Riser (CNR) slot (AC97
interface only)
•
Two IDE channels and a floppy disk drive interface
The L4S5M supports Ultra DMA bus mastering with transfer
rates of 33/66/100 MB/sec.
Integrated I/O The mainboard has a full set of I/O ports and connectors:
