Chapter 1 Motherboard 4845GLM
The 4845GLM motherboard is an integration of Intel
P4 CPUs in Socket-478 packaging and the North Bridge
i845GL supporting 400 MHz Front Side Bus.
North Bridge i845GL on board also supports DDR 266/
200DRAMsinDDR266MHzmainbandwidth,whiletheSouth
Bridge ICH4 provides stable supports of ULTRA ATA 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, Windows NT , Windows ME, Windows
2000, Novell, OS/2, Windows 95/98, Windows 98SE, Win-
dows XP, UNIX, Liunx, SCO UNIX etc. This user-friendly
manual is to describe in detail how to install, configure and
usethis motherboard with drivers andBIOS setup illustrations.

Socket 478
This motherboard is designed with Socket 478 for
Intel P4TM processor.
Pin 1
1.5CPUandCPUFanInstallation
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.

1.5.2 CPU Fan Installation with P4 Fan Base
1. P4 CPU Fan is typically made of 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 con-
nectors on board.
5. Make sure that the Fan Power Cable is correctly connected
to Fan Connector.
