2.4.1. Installation of the CPU
To install your processor, please complete the following set of instructions
1. Locate a small dot marked on the top of the CPU. This mark indicates Pin
1 of the CPU.
2. Locate Pin 1 for the Socket on the mainboard.
3. There is a lever on the side of the socket. First push this lever sideways
and then lift it to a 90-degree angle.
4. Insert the CPU into the Socket. Please make sure that Pin 1 for the CPU
is inserted into Pin 1 of the Socket.
5. When the CPU is installed correctly push the lever back into place.
6. Install a proper heat sink with cooling fan for proper heat dissipa-
tion. Failing to install a heat sink with cooling fan may cause overheating
which will burnout your CPU and damage your mainboard. The heat sink
with cooling fan should be installed on the retention mechanism that is
provided. This retention mechanism is designed to hold the bigger Heat
Sink that is required for the Pentium 4 CPU.
2.4.2. Memory Modules
These mainboards all have three 168-pin SDR SDRAM slots. The SDR SDRAM slots
are located on the right hand side of the board. To install the DIMM’s into these
slots, make sure the white lever at each side of the slot has been pulled down to
an angle of approximately 45°. Make sure that the DIMM is in the correct orienta-
tion. Place the DIMM on the slot and push down firmly.The white levers will come
back up and lock the module in place.
These mainboards support 133MHz SDR SDRAM. SDR SDRAM memory devices
with densities of 64Mb, 128Mb, 256Mb and 512Mb technology x8 or x16 are sup-
ported by the Intel 845 chipset memory interface. Three double sided DIMMs
with unbuffered PC133 can be supported. A maximum memory bandwidth of 1GB/
s is possible with PC133.
Heat Sink and Retention Mechanism
You must use an Intel approved Heat Sink. This CPU operates at a very high fre-
quency and therefore heats up very quickly. (A normal heat sink will not be ade-
quate to cool the CPU and the CPU will burn-out.) These heat sinks are very
heavy. A retention mechanism for the Heat Sink has been provided with the main-
board.

Important: The DIMM’s can only be fitted into the slots in one orientation. Make
sure that the DIMM’s are in the correct orientation and the pins are correctly
aligned before you insert them.
2.4.3. PCI Slots
These boards come with six PCI slots. They are located on the left hand side of
the board. Both PCI and PCI expansion cards may require IRQ’s. This mainboard
complies with Plug and Play (PnP) specifications. Whenever a PnP compliant card
is added the system will automatically be configured and the IRQ’s will be as-
signed automatically.
When you are inserting your PCI card make sure that the pins are correctly
aligned. When the pins are properly aligned with the hole’s in the slot, push down
gently.

NOTE: “Out Of Memory” Error Message
If you have installed more than 512 MB of RAM and are running Microsoft Windows Millennium Edition, Win-
dows 98 Second Edition, Windows 98 or Windows 95 you may experience memory problems. Two symptoms
of these problems are being unable to runan MS-DOS session while you are running Windows or the computer
may stop responding while Windows isstarting.
Thereare three possible solutionsto thisproblem:
1) Reduce the amount of memory Vcache uses to 512 MB or less by altering the MaxFileCache setting in
the System.ini file.
2) Use the System Configuration Utility to reduce the amount ofmemoryWindows uses to 512 MBor less.
3) Reduce the memory installed on your computer to 512 MB or less.
This problem can also occur if you are using an Advanced GraphicPort (AGP) video adapter.

2.4.4. AGP (Accelerated Graphics Port) Slot
AGP is a dedicated bus slot. It operates at 66 MHz and transfers data at a rate up
to 1066 MB/s. This allows 3D applications to run more smoothly. The 845S main-
boards each come with one AGP slot. This slot is able to support 1x, 2x and 4x
AGP cards.
Only 1.5 volt AGP graphic cards are supported by the Intel® 845 chipset
motherboards. If a 3.3 volt AGP card is used in an Intel® 845 chipset
based motherboard there is a high probability of damaging the chipset,
the mainboard and the CPU.

tors labled from CN15-A to CN15-C. CN15-A and the CN15-B are regular ATX
power supply connectors that have been used on all recent motherboards. The
CN15-C power connector is for a +3.3V and +5V power supply. These increased
power supplies are necessary to provide extra power for the slot. The ATX 12V
power supplies are all downward compatible with standard ATX power supplies.
2.5.2. Primary and Secondary IDE connectors
Connector: CN 9 (primary)/ CN 10 (secondary)
Type: 40 pin blocks
The 845S mainboards all have two IDE connectors: a primary and secondary.
Each IDE connector can support two IDE drives. These mainboards can therefore
support up to four IDE devices each. If you install two hard drives, you need to
configure the second drive to slave mode in the BIOS setup
.
Please refer to your
hard drive manual for the appropriate jumper settings.

2.5.5. WOL (Wake On LAN) Connector
Connector: CN 16 (WOL)
Type: 3 pin
The WOL connector must be connected to a LAN card that has Wake-On-LAN
(WOL) output. This connector powers up the system when a wakeup packet or
signal is received through the LAN card.
In order to use the WOL LAN card to trigger the power on the PC system, the
switching power supply must have the ability to provide a driving current of at
least 720 mA and be connected to a “5V standby” voltage.
