which cannot match the P4 Fan base on board.
2. Install the P4 CPU fan into the Fan base in such a way that
the 4 latches of the CPU Fan match with the 4 Supporters of
the CPU Fan Base.
3. Press down the latches to lock CPU Fan to the Fan Base.
4. Then connect the Fan Power Cable to one of the Fan con-
nectors on board.
5. Make sure that the Fan Power Cable is correctly connected
to Fan Connector.

This motherboard supports a maximized 2GB DDR 266/
200 SDRAM. It provides two184-pin unbuffered DDR
sockets. It supports 64MB to 1GB DDR memory module.
DDRSDRAMInstallationProcedures:
1. The DDR socket has a “Plastic Safety Tab” and the DDR
memory module has an asymmetrical notch”, so the DDR
memory module can only fit into the slot in one direction.
2. Push the tabs out. Insert the DDR memory modules into the
socket at a 90-degree angle then push down the module
vertically to fit it into place.
3. The Mounting Holes and plastic tabs should fit over the
edge and hold the DDR memory modules in place.
Warning: Be sure to turn off system power whenever to insert or
remove a Memory Module. Otherwise, the power will damage the
module or even the system.

1.7.1.3 Serial Interface Port: COM1
The serial interface port is sometimes referred to as an RS-
232 port or an asynchronous communication port. Mice,
printers, modems and other peripheral devices can be
connected to a serial port. The serial port can also be used
to connect computer systems together . If you like to transfer
the contents of your hard disk to another system, it can be
accomplished with serial port.
1.7.1.4 VGA Interface Connector: VGA(15 Pin)
This connector is for output to CRT display devices.
1.7.1.5 Parallel Interface Port
Unlike serial ports, parallel interface ports have been
standardized and should not present any difficulty interfacing
peripherals to your system. Sometimes called a Centronics
port, the parallel port is almost exclusively used with printers.
The parallel port on your system is a 25-pin, DB 25 connector.
1.7.1.6 Joystick / Midi Connector
You can connect a joystick or game pad to this connector.
1.7.1.7 Audio Port Connectors
Speaker out is a connector for Speakers or Headphones.
Line in is used for external CD player, Tape player, or other
audio devices. Mic is a connector for the microphones.

This connector supports the provided floppy drive ribbon
cable. After connecting the single end to the board, connect
the two plugs on the other end to the floppy drives.
1.7.4 Hard Disk Connectors: IDE1/IDE2
These connectors are provided with IDE hard disk ribbon
cable into the package . After connecting the end of cable
with single connector to the mainboard, connect the other
two connectors at the other end to your hard disk. If you
install two hard disks, you must configure the second drive
to Slave mode by setting its jumper settings. BIOS now
supports SCSI device or IDE CD-ROM boot up (see "HDD
Sequence SCSI/IDE First" & "Boot Sequence" in the BIOS
