2. US 2.0 Driver Limitations:
2-1 The US 2.0 driver only supports Windows XP and
Windows 2000.
2-2 If you connect a US 2.0 hub to the root hub, plugging US
devices into this hub, the system might not successfully
execute certain US devices’ connection because it could
not recognize these devices.
Currently, we are working on such limitations’ solution. As soon
as the solution is done, the updated US drive will be released to
our website: www.pcchips.com.tw for your downloading.

Introduction
This mainboard has a Socket 4 8 for the Intel Pentium 4 type of
processors supporting front side bus (FS ) speeds up to 400 MHz.
This mainboard has the VIA VT8 51(P4M266) Northbridge and
VT8235 Southbridge chipsets that support AC 9 audio codec,
and provide Ultra DMA 33/66/100/133 function. 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. This mainboard has two 32-bit PCI
slots, one 4xAGP slot, one CNR (Communications and
Networking Riser) slot, and an onboard 10BaseT/100BaseTX
Network interface (optional). In addition, this mainboard 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, one MIDI/game
port and maximum six US ports (USB 2.0) --two back-panel
ports and onboard US headers make four extra US ports by
connecting the Extended US Module to the mainboard.
This mainboard is a Micro ATX size mainboard and has power
connectors for an ATX power supply.
