Mainboard User's ManualPage 44
Your mainboard may come with an optional onboard LAN func-
tion. It utilizes the Intel 82562ET Physical Layer Interface,
which is IEEE 10BASE-T and 100BASE-TX compliant. If your
mainboard does come with an onboard LAN function, make sure
it is enabled in the BIOS setting under “Integrated Peripherals” in
order to use it. If you rather install and use the LAN function on
the CNR card, make sure you disable the onboard LAN function
and select “EXT. CNR” in the BIOS setting. The reason being
that they both share the same LAN controller on the ICH2 chip.
Only one physical layer interface can uses the LAN controller at
a time, otherwise conflict will occur.
c Universal Serial Bus (USB) Header
Connect this header to the optional USB extension cable for
a USB port.
D Serial (COM1 & 2) Headers
The Mainboard provides two 9-pins serail port headers.
E Infrared (IR) Header
The Mainboard provides a 5-pin header interface, IR
for connection to a Hewlett Packard HSDSL-1000 compatible
infrared (IrDA) transmitter/receiver. Connect IR to the front panel
I/O IrDA connector provided with your system. Once the module
is connected to the front panel I/O IrDA connector, Serial port
2 can be re-directed to the IrDA module. When configured for
IrDA, the user can transfer files to or from portable devices such
as laptops, PDA’s, mobile phone and printers using application
software such as LapLink. The IrDA specification provides for
data transfers at 115 kbps from a distance of 1-meter. Support
for Consumer infrared (ASK-IR) is also included. Please refer to
your IR equipment for more detailed information.
