Chapter 1
Introduction
This motherboard has a VIA C3 CPU onboard with front-side bus
speed up to 133MHz.
This motherboard integrates the VIA CLE266 Northbridge and
8235 Southbridge chipsets that support DDR 266MHz, Ultra
DMA 33/66/100/133 function and remarkably high system
performance under all types of system operations
It supports built-in USB 2.0 providing higher bandwidth. It
implements Universal Serial Bus Specification Revision 2.0 and
is compliant with UHCI 1.1 and EHCI 0.95. The motherboard
supports the built-in AC’97 Codec, two 32-bit PCI slots, one CNR
(Communications and Networking Riser) slot, and an onboard
10BaseT/100BaseTX Network interface (optional). This
motherboard integrates a 128-bit 3D/2D graphics engine and a
high-performance 3D accelerator.
In addition, this motherboard has a full set of I/O ports including
two PS/2 ports for mouse and keyboard, one serial port, one VGA
port, one parallel port and six USB2.0 ports– four back-panel ports
and onboard USB header USB1 providing two extra ports by
connecting the Extended USB Module to the motherboard.
This motherboard has all the features you need to develop a
powerful multimedia workstation. The board is FLEX ATX size
and has a power connector for an ATX power supply.
