Glossary
A PS/2 Mouse & Keyboard Connector
The Mainboard provides two on-board PS/2 connectors, one for
the keyboard, and one for the mouse. PS/2 devices all have
a standard 6-pin round shape connector. If you are already
using a PS/2 mouse or keyboard, simply plug them into the
corresponding connector. No jumper settings are necessary.
B ATX Power Supply Connector
The Mainboard provides a single 20-pin ATX power supply
connector, which incorporates standard +5V and +12V, 3.3V
and soft-on/off signals. With a power supply that supports
remote power on/off, the mainboard can turn off the system
power through software control, such as the shutdown command
in the Windows 95 / Windows 98 Start Menu. The BIOS
system will turn the system power off when it receives the
proper APM command from the OS. APM must be enabled in
the BIOS and OS systems in order to set the soft-off feature
working properly.

About the Soft Touch Power Button
In an ATX based system, the new soft touch power button
replaces the main power switch that turns your system on and
off. From an OFF state, you can switch the system ON by simply
pressing the power button. From an ON state, the system can
be turned OFF by pressing and holding the power button for four
(4) seconds OR shut down instantly. The functions of the power
button can also be altered in the Power Management section
of the CMOS setup.
C Universal Serial Bus (USB) Connector
The Mainboard provides four 4-pin Universal Serial Bus
(USB) connectors. USB is a new interface standard for adding
external Plug-and-Play (PnP) devices to the computer system.
Peripherals that support USB PnP capabilities can operate at up
to a 12Mb/sec data transfer rate. Eventually, all external devices
connected to your computer will be standardized to USB.
D Serial (COM1 & 2) Connector
The Mainboard provides two high-speed 16550 compatible UART
serial ports.
E Infra-Red (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 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.

F Memory Module Sockets
The Mainboard provides 168 pin standard DIMM sockets for
installation of 3.3V unbuffered Single or Double Bank SDRAM
modules.
G Parallel Port Connector
The ATX Mainboard provides a parallel port connector. Based
on the ATX standard, a 25-pin parallel port is now built on
the mainboard back panel. This design makes the mainboard
installation easier. The parallel port can be BIOS configured
into standard (SPP) mode, Enhanced Parallel Port (EPP) mode,
and a high speed Extended Capabilities Port (ECP) mode. EPP
Mode requires a driver provided by the peripheral manufacturer
in order to operate properly.
H Accelerated Graphics Port [AGP] Connector
The Mainboard provides an AGP slot compatible with the
Accelerated Graphics Port specification. AGP compliant video
cards offer a much higher throughput than equivalent PCI bus
video cards. PCI currently only supports a 33MHz bandwidth,
and can transport at peak rates up to 133MB/s over its 32
bit data bus. AGP operates at a 66MHz bandwidth which
enables a peak rate of 266MB/s in what is known as 'X1'
mode. Using 'X2' mode, the peak transport rate can go as
high as 532MB/s.

I LITHIUM BATTERY
A 3V, CR2032, Lithium battery is installed on the on-board
battery socket. This battery is used to supply the CMOS
RAM backup power during system powered-off. Danger of
explosion if battery is incorrectly replaced. Therefore, if you
have any difficulties, please consult the technical personnel.
J PCI Add-In Board Connector
The Mainboard provides 5 PCI Connector for the PCI cards.
L Modem Connector (Optional)
Connect the "MODEM connector" to the Telephone Jack extension
cable for the optional onboard 56Kbps modem.
M Front Panel Function Connector
The Mainboard integrates all system front panel functions into
a single on-board connector. These include connections for the
following features:

N Flash BIOS
The Mainboard flash BIOS provides users with more flexibility
in upgrading their mainboards. The flash BIOS can be easily
reprogrammed via software.
O Floppy Drive Header
The Mainboard provides a 34-pin connector that supports
the included floppy drive ribbon cable. After connecting the
single end to the on-board “FLOPPY” connector, connect
the remaining plugs on the other end of the cable to the
corresponding floppy drives.
NOTE: Pin 5 is removed to prevent inserting the connector
in the wrong orientation.
P IDE Device Header
The Mainboard provides (2) independent bus-mastering PCI
IDE interfaces capable of supporting up to Mode 4 and Ultra
DMA-33/66/100 devices. The system BIOS supports automatic
detection of the IDE device data transfer rate and translation
between different kinds of device modes such as Logical Block
Addressing (LBA), Extended Cylinder Sector Head (ECSH)
translation modes and ATAPI (e.g., CD-ROM) devices on both
IDE interfaces.
The two on-board IDE headers support the provided 80-pin IDE
hard disk ribbon cables. If you install two hard disks and/or
CD-Rom drives, you must configure the two drives by setting
their IDE master/slave jumpers according to the documentation
for those devices.
Also, you may connect the two hard disk drives so that both
become Masters, using one ribbon cable on the primary IDE
header and one on the secondary IDE header.

Q WAKEUP-LINK Header
The Mainboard provides on WAKEUP-LINK header (WOL)
used to connect an add-in Network Interface Card which has
Wakeup capability.
R Universal Serial Bus Header
Connect this header to the optional USB extension cable for
two USB ports.
r "CNR" Add-in Board Connector
Communication & Networking Riser(CNR) is a new interface
standard for Networking or modem add-in card.
S CPU Socket
The Mainboard provides a 370-pin CPU Socket for Intel
Celeron, PIII or Cyrix III processor. The CPU should have a fan
attached to it to prevent overheat. If a fan is not present, a fan
should be installed prior to turning the system on.
