Introduction
The 845D-AV MAINBOARD Ver 3.x Page 9
The mainboard is capable of monitoring the following health conditions of your
system:
1. Processor temperature. It has an overheat alarm.
2. VCORE/3.3V/5V/12V/-12V voltages and failure alarm.
3. Processor and chassis fan speeds. It has a failure alarm for these fans.
4. Read back capability that displays temperature, voltage and fan speed.
1.4.1. Hardware Monitoring System Utility
The 845D-AV mainboard comes with the Hardware Monitoring System utility
contained on the CD. It is capable of monitoring the systems hardware
conditions such as the temperature of the processor, voltage, and the speed of
both the CPU and chassis fans. You are allowed to manually set a range to the
items being monitored. If the values are over or under the set range a warning
message will automatically pop up. We recommend that you use the Default
Settings, which are the ideal settings that will maintain the system in a good
working condition.
1.4.2. Installation
To install this utility, please insert the CD into the CD-ROM drive. The auto run
screen (Driver Utility) will automatically appear. Click the Hardware Monitoring
button, choose the chipset, model number and the OS that is installed. Please
refer to the CD “Readme” file for further installation instructions.
Note: Only use this utility in Windows®95 or Windows®98 operating systems.
Introduction
%"!&'( !
Dual Function Power Button
Depending on the setting in the Soft-Off By Power-Button field of the Power
Management Setup, this switch allows the system to enter the Soft-Off or
Suspend mode.
RTC Timer to Power-on the System
The RTC installed on the system board allows your system to automatically
power-on at a set date and time.
Wake-On-LAN Ready
The Wake-On-LAN function allows the network to remotely wake up a Soft
Power Down (Soft-Off) PC. Your LAN card must support the remote wakeup
function. The 5V SB power source of your power supply must be at least
720mA.
ACPI Ready
The mainboard is designed to meet the ACPI (Advanced Configuration and
Power Interface) specification. ACPI has energy saving features that support
OS Direct Power Management (OSPM) for round the clock PC operation.

2.4.2. Memory Modules
The 845D-AV mainboard has two 184-pin DDR DIMM slots and are able to
support a maximum memory of 2 GB. The DDR DIMM slots are located on the
right hand side of the board. To install the DIMMs 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 orientation.
Place the DIMM on the slot and push down firmly.The white levers will come
back up and lock the module in place.
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 cor-
rectly aligned before you insert them.
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 side-
ways 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 dissi-
pation. Failing to install a heat sink with cooling fan may cause over-
heating which will burnout your CPU and damage your mainboard.
IMPORTANT: CPU COOLING FAN
Please ensure that you have an approved heat sink with cooling fan. Without a
proper heat sink with cooling fan you will damage both the mainboard and the
CPU.

2.4.3. PCI Slots
The 845D-AV mainboard comes 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. When-
ever a PnP compliant card is added the system will automatically be configured
and the IRQ’s will be assigned 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.

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
845D-AV mainboard comes with a 1.5V AGP slot. This slot is able to support
1x, 2x and 4x AGP cards.
Note: Only 1.5 volt AGP graphics cards are supported by the Intel®845 chip-
set 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 main-
board and the CPU. (Please see Appendix A)

The FDD connector can support two Floppy drives. It is located at the front of
the mainboard. To connect, use the ribbon-cable that has been provided.
Make sure that the red strip is connected to PIN 1 of the connector.
2.5.2. Primary and Secondary IDE connectors
Connector: CN 9 (primary)/ CN 10 (secondary)
Type: 40 pin blocks
The 845D-AV mainboard all have two IDE connectors: a primary and secon-
dary. 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.

The 845D-AV mainboard has a WOL (Wake-On-LAN) connector. This connec-
tor 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 re-
ceived 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.

tors). The internal USB connectors allow you to add on an optional kit to ex-
pand the total number of USB ports available. The 845D-AV has two internal
USB connectors (CN30 and CN31). This enables you to use an extra two USB
devices. Cable for these additional connectors needs to be purchased sepa-
rately.
Note: These are not the standard USB connectors you find on the ATX PC99
connector. To connect USB devices you need to use an expansion cable
(purchased separately) that ends in a standard USB connector. Ask your re-
tailer for more details.

Option 1: If you choose “Delay 4 Sec.” In the BIOS CMOS Setup, the func-
tion of “PW” will be:
A. When the system power is "OFF", press this switch, the system will
power on.
B. When system power is "ON”, you can select two different modes: -
Mode 1: Press and hold the Power ON button for less than 4 seconds and then
release it. The system will be turned into Suspend mode (turned into the
GREEN mode) When the system is in the Suspend mode:-
!Press the Power on button (less than 4 seconds), the system will return
to Full-ON mode.
!Press and hold the Power On Button for more than 4 seconds, the
system will be powered off.
Mode 2: Press and hold the Power ON button for more than 4 seconds, the
system will be completely powered off.
Option 2: If you choose “Instant OFF.” In the BIOS CMOS Setup, the power
switch will operate like a normal ON / OFF Power button.
2.6.2. HL: HDD LED Connector
Any read and write activity by the HDD will turn this LED on.
2.6.3. RS: Reset Button Connector
If you connect this connector, you will be able to reset you computer by press-
