The user can connect to the ISP using a modem installed in the computer and connected to a phone line. LAN (Local Area Network). A network technology designed to connect computers that are separated by a short distance. The local group of linked computers are normally connected to a single server. See also WAN (Wide Area Network) Modem. A device that allows a computer to talk to another computer through the phone system. Network. An interconnected computer system linked by telephone wires, or other means. OS (Operating System). The software that controls the overall operation of a computer system. The OS tasks include memory allocation, input and output distribution, interrupt processing, job scheduling, and various other duties. PC100/PC133. This is an industry-standard designation for memory capacity as a measure of the speed of the memory bus. New platform requirements ensure that memory does not become a bottleneck to system performance. PCI Bus (Peripheral Component Interconnect Local Bus). PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard widely used by expansion card manufacturers. PCI Bus Master. The PCI Bus Master can perform data transfer without local CPU help and furthermore, the CPU can be treated as one of the Bus Masters. PCI 2.1 supports concurrent PCI operation to allow the local CPU and bus master to work simultaneously.
POST (Power On Self Test). When you turn ON the computer, it will first run through the POST, a series of software-controlled diagnostic tests. The POST checks system memory, the motherboard circuitry, the display, the keyboard, the diskette drive, and other I/O devices. PS/2 Port. PS/2 ports are based on IBM Micro Channel Architecture. This type of architecture transfers data through a 16-bit or 32-bit bus. A PS/2 mouse and/or keyboard may be used on ATX motherboards. RAM (Random Access Memory). The computers primary storage area used to write, store, and retrieve information and program instructions which are passed to the CPU for processing. The information in RAM can be repeatedly re-written with new data. Compared to other storage media like magnetic tape, floppy disk, and hard disk, RAM has an extraordinarily fast access rate. RAM, however, is volatile, which means that the data stored in it are lost when the system power is turned off, or if power glitches occur. See also DRAM and SDRAM. ROM (Read Only Memory). An integrated circuit chip containing program and data that can be accessed and read but not modified. SCSI (Small Computer System Interface). High speed multi-threaded I/ O interface defined by the X3T9.2 committee of the American National Standards Institute (ANSI) for connecting many peripheral devices. The standard covers 10MBytes/sec to 160MBytes/sec data rates. SDRAM (Synchronous DRAM). A type of DRAM with access signals that are synchronized with the CPU clock, eliminating the delay associated with data transfers between the CPU and memory. SDRAM takes memory access away from the CPU control; internal registers in the memory accept the request, and lets the CPU do something else while the data requested is assembled for the next time the CPU talks to the memory. SIR (Serial IrDA). A SIR specification defines a short-range infrared asynchronous serial transmission mode with one stat bit, eight data bits and one stop bit. The maximum data rate is 115.2Kbps. SPD for SDRAM module. Serial Presence Detect (SPD) is most like an ID detect for SDRAM module, it uses an EEPROM component on a DIMM for storing module configuration information inside. The Serial Presence Detect function is implemented using a 2048 bit EEPROM component. This nonvolatile storage device contains data programmed by the DIMM manufacturer that identifies the module type and various SDRAM organization and timing parameters.

The use of shielded cables for connection of the monitor to the graphics card is required to assure compliance with FCC regulations. Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the users authority to operate this equipment.

2.5.1 Overview
The motherboard comes with two Double Data Rate (DDR) Dual Inline Memory Module (DIMM) sockets. These sockets support up to 2GB system memory using 184-pin unbuffered ECC or non-ECC PC2100/1600 DIMMs.

104 Pins

80 Pins
P4B533-M 184-Pin DDR DIMM Sockets
A DDR DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into a socket to avoid damaging the DIMM.
The DDR SDRAM technology evolved from the mainstream PC66, PC100, PC133 memory known as Single Data Rate (SDR) SDRAM. DDR memory however, has the ability to perform two data operations in one clock cycle, thus providing twice the throughput of SDR memory. For example, a 200MHz DDR DIMM will support a 100MHz memory bus, and a 266MHz DDR DIMM will support a 133MHz memory bus.
DDR Data Transfer Rate 266MHz 200MHz DDR Base Frequency 133MHz 100MHz
A DDR DIMM has the same physical dimensions as an SDR DIMM, but it has a 184-pin footprint compared to the 168-pin of the SDR DIMM. Also, a DDR DIMM is single notched while an SDR DIMM is double notched. Therefore, a DDR DIMM is not backward compatible with SDR, and should be installed only in a socket specially designed for DDR DIMMs.
2.5.2 Memory configurations
You may install any DDR DIMMs with 64MB, 128MB, 256MB, 512MB, and 1GB densities into the DIMM sockets.

Support the DIMM lightly with your fingers when pressing the retaining clips. The DIMM might get damaged when it flips out with extra force.
2. Remove the DIMM from the socket.

Expansion slots

In the future, you may need to install expansion cards. The motherboard has three PCI slots and one Accelerated Graphics Port (AGP) slot. The following sub-sections describe the slots and the expansion cards that they support.
Make sure to unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components.
2.6.1 Installing an expansion card
Follow these steps to install an expansion card. 1. Before installing the expansion card, read the documentation that came with it and make the necessary hardware settings for the card. 2. Remove the system unit cover (if your motherboard is already installed in a chassis). 3. Remove the bracket opposite the slot that you intend to use. Keep the screw for later use. 4. Align the card connector with the slot and press firmly until the card is completely seated on the slot. 5. Secure the card to the chassis with the screw you removed earlier. 6. Replace the system cover.
2.6.2 Configuring an expansion card
After installing the expansion card, configure the it by adjusting the software settings. 1. Turn on the system and change the necessary BIOS settings, if any. See Chapter 4 for information on BIOS setup. 2. Assign an IRQ to the card. Refer to the tables on the next page. 3. Install the software drivers for the expansion card.
Standard Interrupt Assignments
IRQ 2 3* 4* 5* 6 7* 8 9* 10* 11* 12* 13 14* 15* Priority N/A 10 Standard Function System Timer Keyboard Controller Programmable Interrupt Communications Port (COM2) Communications Port (COM1) Sound Card (sometimes LPT2) Floppy Disk Controller Printer Port (LPT1) System CMOS/Real Time Clock ACPI Mode when used IRQ Holder for PCI Steering IRQ Holder for PCI Steering PS/2 Compatible Mouse Port Numeric Data Processor Primary IDE Channel Secondary IDE Channel

These IRQs are usually available for ISA or PCI devices.
IRQ assignments for this motherboard
A B C D E F G H used used shared shared shared used shared used used used
PCI slot 1 PCI slot 2 PCI slot 3 AGP slot Onboard USB controller 1 Onboard USB controller 2 Onboard USB controller 3 Onboard USB 2.0 controller Onboard audio Onboard LAN
When using PCI cards on shared slots, ensure that the drivers support Share IRQ or that the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI groups, making the system unstable and the card inoperable.

2.6.3 PCI slots

There are three 32-bit PCI slots in this motherboard. The slots support PCI cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI specifications. The following figure shows a LAN card installed on a PCI slot.

2.6.4 AGP slot

This motherboard has an Accelerated Graphics Port (AGP) slot that supports +1.5V AGP cards. When you buy an AGP card, make sure that you ask for one with +1.5V specification. Note the notches on the card golden fingers to ensure that they fit the AGP slot on your motherboard. If you installed an incorrect AGP card, such as a SiS305-based AGP card or any other 3.3V AGP card, the onboard red LED (AGP_WARN) lights up, an indication that the card is not supported on the motherboard. As long as this LED is lighted, you cannot turn on the system power even if you press the power button, thus preventing permanent damage to the motherboard.
Install only 1.5V AGP cards on this motherboard!

BIOS Setup program

This motherboard supports a programmable Flash ROM that you can update using the provided utility described in section 4.1 Managing and updating your BIOS. Use the BIOS Setup program when you are installing a motherboard, reconfiguring your system, or prompted to Run Setup. This section explains how to configure your system using this utility. Even if you are not prompted to use the Setup program, you may want to change the configuration of your computer in the future. For example, you may want to enable the security password feature or make changes to the power management settings. This requires you to reconfigure your system using the BIOS Setup program so that the computer can recognize these changes and record them in the CMOS RAM. The Flash ROM on the motherboard stores the Setup utility. When you start up the computer, the system provides you with the opportunity to run this program. Press <Delete> during the Power-On Self Test (POST) to enter the Setup utility, otherwise, POST continues with its test routines. If you wish to enter Setup after POST, restart the system by pressing <Ctrl> + <Alt> + <Delete>, or by pressing the reset button on the system chassis. You can also restart by turning the system off and then back on. Do this last option only if the first two failed. The Setup program is designed to make it as easy to use as possible. It is a menu-driven program, which means you can scroll through the various sub-menus and make your selections among the predetermined choices.
Because the BIOS software is constantly being updated, the following BIOS setup screens and descriptions are for reference purposes only, and may not exactly match what you see on your screen.
