Chapter 1 Motherboard 4845GVQ
The 4845GVQ motherboard is an integration of Intel P4
CPU in Socket-478 packaging and the North Bridge i845GV
supporting 400/533 MHz Front Side Bus.
North Bridge i845GV on board also supports DDR 266/
200 SDRAMs in DDR 266MHz main bandwidth, while the
South Bridge ICH4 provides stable supports of ULTRAATA
100, 6-channel Audio playback and USB 2.0/1.1 interface.
The resulting architecture will provide an ideal multi-task
environment to support operating systems such as MS-DOS,
Windows,WindowsNT,WindowsME,Windows2000,Novell,
OS/2, Windows 95/98, Windows 98SE, Windows XP, UNIX,
Liunx, SCO UNIX etc. This user-friendly manual is to de-
scribe in detail how to install, configure and use this

1. Pull the lever sideways away from the socket then raise the
lever to a 90-degree angle.
2. Locate Pin 1 in the socket Pin 1 of CPU is marked by the yellow
corner or cut edge on the CPU. Match Pin 1 of Socket 478 and
Pin 1 of CPU.
3. Pull up the lever of Socket 478 to let the CPU in and press the
lever down to lock the CPU.
4. Make sure that Pin 1 of Socket 478 is matching with Pin 1 of
CPU.
5. Make sure that all CPU pins are completely in socket before
pressing down the socket lever.

1. P4 CPU Fan is typically designed with 4 latches and mounted
with a thick heatsink. Please do not use other type of CPU fan
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 connec-
tors on board.
5. Make sure that the Fan Power Cable is correctly connected to
Fan Connector.

This motherboard supports a maximized 2GB DDR
SDRAM. It provides two184-pin unbuffered DDR sockets.
It supports 64MB to 1GB DDR memory module.
DDRSDRAMInstallationProcedures:
1.TheDDR socket hasa“PlasticSafetyTab” andtheDDR memory
module has an asymmetrical notch”, so theDDR memory mod-
ule 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 verti-
cally to fit it into place.
3. The Mounting Holes and plastic tabs should fit over the edge
and hold theDDR memory modules in place.
Warning: Be sure to turn off system power wheneverto 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)
Thisconnectoris foroutput toCRTdisplaydevices.Forexample,
connect this connector directly to a CRT monitor for CRT
display.
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.

The connector can be connected to a reset switch. Press this
reset switch to restart system.
This allows the user to manually place the system into the
Suspend Green mode . System activity will be instantly
decreased to save electricity and expand the life of certain
components when the system is not in use. This 2-pin connector
(see the figure) connects to the case-mounted suspend switch.
If you do not have a switch for the connector, you may use the
"Turbo Switch” instead since it does not have a function. If
you want to use this connector, the "Suspend Switch" in the
Power Management Setup of the BIOS SOFTWARE section
should be enabled.
