•BackPanelConnectors

The motherboard external IO connectors are attached to a metallic I/O shield.

This shield serves several purposes:

•It protects the sensitive motherboard from any external EMC interference.

•It stops the computer from interfering with other electrical devices.

•It allows the motherboard to be easily upgraded in the future without having to

resort to buying a whole new case. Simply change the I/O shield to match the

motherboard.

The I/O shield provides external access to PS/2 keyboard and mouse connectors

as well as one serial port, one parallel port, two USB ports, one LAN Port and the

audio connectors.

Note: Power to the computer should be turned off before a keyboard or mouse

are connected or disconnected.

•MemoryConfigurations

The Intel 82875P MCH component provides two features for enhancing memory

throughput:

•Dual Channel memory interface. The board has two memory channels,

each with two DIMM sockets, as shown in Figure 3

•Dynamic Addressing Mode. Dynamic mode minimises overhead by

reducing memory accesses

Table 4 summarises the characteristics of Dual and Single Channel

configurations with and without the use of Dynamic Mode.

DDR SDRAM) and “SS”

refers to single-sided memory modules (containing one row of DDR SDRAM).

When ECC DIMMs are used, the Power-On Self Test (POST) will take longer to complete.

•SystemBoardJumperSettings

The Configuration Jumper (J7J2) allows the user to enter the configuration mode,

and to recover from a corrupted BIOS update. The following figure shows the

location of the header on the motherboard. The audio jumper block (J9A2)

allows the implementation of front panel audio.

Single-Jumper Configurations

J7J2 Configuration

Normal 1-2 The BIOS uses current configuration information and passwords for

booting.

Configure 2-3 After the POST runs, Setup runs automatically. The maintenance

menu is displayed.

Recovery None The BIOS attempts to recover the BIOS configuration. A recovery

diskette is required.

CAUTION!

Do not move the jumper with the power on. Always turn off the power and

unplug the power cord from the computer before changing the jumper.

Note: There is no jumper setting for configuring the processor speed or bus

frequency. The feature for configuring the processor speed is in the Setup

program using configure mode. See Manual BIOS Section for information about

configure mode.

•MotherboardConnectors

There are connectors on the motherboard for FAN, IDE, Power supply, CD

audio, Floppy, IDE, & Front Panel Connectors. The location and/or details of

these connections are shown below.

Motherboard Connectors

•FrontPanelConnectors

The following are all connectors situated along the front edge of the

motherboard. They are often connected to buttons and LED’s situated on the

front panel.

Note: Power LED single colour LED + pin 2 , Dual colour LED + pin 4

Front panel connectors

A-Hard Disk L.E.D. Connector

This goes to the Hard Disk L.E.D. on the front panel, which lights up when the IDE Hard

Disk is in use.

B - Reset switch connector

When these pins are shorted, it will cause the computer to perform a cold reboot.

C - Power L.E.D.

This attaches to the power L.E.D on the front panel, to display if the computer is active

or not.

D- Power On/Off

When these pins are shorted it turns the computer on and off.

Upgrading the CPU

CAUTION!

Allow time for the processor and heatsink to cool before touching either of them.

The Pentium 4 processor together with Level 2 cache chips are housed in a

protective package.

The design of the D875PBZ computer makes it a simple job to replace or

upgrade the processor. To do so please refer to figure 15 and follow the

instructions below:

1. Read the warnings at the start of this chapter and ensure a static free

environment

2. Remove the lid from the computer by removing the four screws at the rear of

the case

3. Locate the CPU module by referring to figure 1 if necessary

4. Locate the heat sink clips, and remove heat sink (and unplug FAN cable)

5. Lift arm on Socket to release the CPU

6. Lift the CPU Vertically upwards until it is clear of the socket

You can now fit the replacement CPU and heat sink into the socket.

above)
