Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.
2.4 Central Processing Unit (CPU)

2.4.1 Overview

The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF) socket. This socket is specifically designed for the Intel Pentium 4 478/Northwood Processor. The Intel Pentium 4 Processor in the 478-pin package uses the Flip-Chip Pin Grid Array 2 (FC-PGA2) package technology, and includes the Intel NetBurst micro-architecture. The Intel NetBurst micro-architecture features the hyper-pipelined technology, rapid execution engine, 400MHz system bus, and execution trace cache. Together, these attributes improve system performance by allowing higher processor frequencies, faster execution of integer instructions, and a data transfer rate of 3.2GB/s.

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 two DIMM sockets. Use the following combinations to install DDR DIMMs.

Chapter 4

BIOS setup

Managing and updating your BIOS
4.1.1 Using the computer system for the first time
It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later. AFLASH.EXE is a Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. This file works only in DOS mode. To determine the BIOS version of your motherboard, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup. Larger numbers represent a newer BIOS file. 1. Type FORMAT A:/S at the DOS prompt to create a bootable system disk. DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk. 2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-ROM drive) to copy AFLASH.EXE to the boot disk you created.
AFLASH works only in DOS mode. It does not work in the DOS prompt within Windows and does not work with certain memory drivers that may be loaded when you boot from the hard drive. It is recommended that you reboot using a floppy disk.
3. Reboot the computer from the floppy disk.
BIOS setup must specify Floppy as the first item in the boot sequence.
4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH.
If the word unknown appears after Flash Memory:, the memory chip is either not programmable or is not supported by the ACPI BIOS and therefore, cannot be programmed by the Flash Memory Writer utility.
5. Select 1. Save Current BIOS to File from the Main menu and press <Enter>. The Save Current BIOS To File screen appears.
6. Type a filename and the path, for example, A:\XXX-XX.XXX, then press <Enter>.

Glossary

This glossary also includes some terms that are not found in this document but might be of help to you when operating, upgrading, or reconfiguring your computer.
AC97 (Audio Codec '97). AC '97 is the next step in enabling PCs with audio quality comparable to consumer electronics devices. The specification defines new cost-effective options to help integrate the components necessary to support next-generation auto-intensive PC applications such as DVD, 3-D multiplayer gaming and interactive music. The specification also defines new extensions supporting modem and docking to help both desktop and mobile manufacturers adopt these new technologies more quickly and cost-effectively. This specification uses software emulation to compete with the PCI SoundBlaster specification. ACPI (Advanced Configuration and Power Interface). The ACPI specification defines a cross-platform interface designed to support many operating systems. ACPI defines a flexible and abstract hardware interface that provides a standard way to integrate power management features in a PC system, including hardware, operating system and application software. This enables the system to automatically turn ON and OFF peripherals such as CD-ROMs, network cards, hard disk drives, and printers, as well as consumer devices connected to the PC such as VCRs, TVs, phones, and stereos. With this technology, peripherals are also able to activate the PC. For example, inserting a tape into a VCR can turn on the PC, which could then activate a large-screen TV and high-fidelity sound system. AGP (Accelerated Graphics Port). An interface specification that enables high-performance 3D graphics on mainstream PCs. AGP was designed to offer the necessary bandwidth and latency to perform texture mapping directly from system memory.

System Disk. A system disk contains the core file of an operating system and is used to boot up the operating system. TCP/IP (Transmission Control Protocol/Internet Protocol). The communications protocol used by the UNIX system and the Internet. TCP checks for lost packets, puts the data from multiple packets into the correct order, and requests that missing or damaged packets be resent. USB (Universal Serial Bus). A 4-pin serial cable bus that allows up to 127 Plug-n-Play computer peripherals (such as keyboard, mouse, joystick, scanner, printer, modem, and monitor) to share bandwidth through a host scheduled token-based protocols. This allows attaching or detaching while the host and other peripherals are in operation. Supports synchronous and asynchronous transfer types over the same set of wires up to 12Mbit/ sec. USB 2.0 provides 40 times the transfer rate compared to USB 1.0 and competes with the 1394 standard. WAN (Wide Area Network). A geographically dispersed network formed by linking several computers or Local Area Networks (LANs) together over long distances. WANs usually use leased long-distance lines to connect systems across towns, in different cities, or in different regions of the world.

Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component. 2. Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity. 3. Hold components by the edges and do not to touch the ICs on them. 4. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component. 5. Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

To select the CPU external frequency using the DIP switches, ensure that the JEN jumper is set to jumper mode.

4. USB device wake-up (3-pin USBV1, USBV2, USBV3) Set these jumpers to +5V to wake up the computer from S1 sleep mode (CPU stopped, DRAM refreshed, system running in low power mode) using the connected USB devices. Set to +5VSB to wake up from S3 sleep mode (no power to CPU, DRAM in slow refresh, power supply in reduced power mode). Both jumpers are set to pins 1-2 (+5V) by default because not all computers have the appropriate power supply to support this feature. The USBV1 jumper is for the rear USB ports. The USBV2 and USBV3 jumpers are for the internal USB headers.
1. This feature requires a power supply that can provide at least 1A on the +5VSB lead when these jumpers are set to +5VSB. Otherwise, the system does not power up. 2. The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.

BIOS setup

Managing and updating your BIOS
4.1.1 Using the computer system for the first time
It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory Writer utility (AFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later. AFLASH.EXE is a Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. This file works only in DOS mode. To determine the BIOS version of your motherboard, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup. Larger numbers represent a newer BIOS file. 1. Type FORMAT A:/S at the DOS prompt to create a bootable system disk. DO NOT copy AUTOEXEC.BAT and CONFIG.SYS to the disk. 2. Type COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-ROM drive) to copy AFLASH.EXE to the boot disk you created.

Before attempting to configure a hard disk drive, make sure you have the correct configuration information supplied by the drive manufacturer. Incorrect settings may cause the system to fail to recognize the installed hard disk.

SDRAM Configuration [By SPD]
This parameter allows you to set the optimal timings for items 24, depending on the memory modules that you are using. The default setting is [By SPD], which configures items 24 by reading the contents in the SPD (Serial Presence Detect) device. The EEPROM on the memory module stores critical information about the module, such as memory type, size, speed, voltage interface, and module banks. Configuration options: [User Defined] [By SPD]

4.5.2 Hardware Monitor

MB Temperature [xxxC/xxxF] CPU Temperature [xxxC/xxxF] POWER Temperature [N/A]
The onboard hardware monitor automatically detects the motherboard and CPU temperatures. If your power supply comes with a two-pin thermal sensor cable, connect this cable to the PWRTMP connector on the motherboard so BIOS can auto-detect the power supply temperature. See page 2-32 for the connector location. The POWER Temperature item shows [N/A] if you do not have the appropriate power supply.
CPU Fan Speed [xxxxRPM] Chassis Fan Speed [xxxxRPM) Power Fan Speed [xxxxRPM]
The onboard hardware monitor automatically detects the CPU, chassis, and power fan speeds in rotations per minute (RPM).
VCORE Voltage, +3.3V Voltage, +5V Voltage, +12V Voltage
The onboard hardware monitor automatically detects the voltage output through the onboard voltage regulators.
If any of the monitored items is out of range, the following error message appears: Hardware Monitor found an error. Enter Power setup menu for details. You will then be prompted to Press F1 to continue or DEL to enter SETUP.

Appendix C: Glossary

Device Driver. A software routine that links a peripheral device to the operating system. It acts as a translator between the device and the applications that use it. Each device has its own set of specialized commands known only to its driver while the applications access devices using high-level generic commands. The driver translates these commands into the commands required by the devices. DOS (Disk Operating System). A software that organizes how a computer reads, writes, and communicate to the disks and various input/ output devices (such as keyboards, screens, serial and parallel ports, printers, modems, etc.) connected to it. DOS was the most popular PC operating system until the introduction of Windows. DRAM (Dynamic Random Access Memory). A type of RAM that requires refresh cycles to prevent the loss of the data stored in it. See also RAM and SDRAM. Expansion Card. A printed circuit card suchas an audio card, a video card, or a LAN card that plugs into an expansion slot on the motherboard. An expansion card add functions that are not present in the motherboard. Flash ROM. A non-volatile memory device that retains its data even when power is removed. This device is similar to EPROM, but unlike EPROM which can be erased only using an ultra-violet light, flash ROM can be electrically erased. Flash ROM is normally used for system BIOS, which initiates hardware devices and sets up necessary parameters for the OS. Since the flash ROM contents can be modified, you can update the BIOS by yourself. IDE (Integrated Drive Electronics). IDE devices integrate the drive control circuitry directly on the drive itself, eliminating the need for a separate adapter card (in the case for SCSI devices). UltraDMA/100/6633 IDE devices can achieve up to 100MB/sec transfers. Internet. The global computer network composed of WANs and LANs that uses TCP/IP to provide worldwide communications to homes, schools, businesses, and the government. I/O (Input/Output). The data transfers from the input devices like a keyboard, mouse, or scanner, to the output devices like a printer or the monitor screen. I/O Address. The specific memory location for a particular device. Two devices cannot share the same I/O address space.
IrDA (Infrared Data Association). An internaltional organization that creates and promotes inter-operable, low cost, infrared data interconnection standards that support a walk-up, point-to-point model. The IrDA protocol is designed to support transmission of data between two devices over short-range point-to-point infrared at speeds between 9.6Kbps and 4Mbps. ISP (Internet Service Provider). A company that provides customer access to the Internet and the World Wide Web for a fee. The ISP also provides Internet utilities and services like e-mail, newsgroup, weather reports, and a host of others. 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.
System Disk. A system disk contains the core file of an operating system and is used to boot up the operating system. TCP/IP (Transmission Control Protocol/Internet Protocol). The communications protocol used by the UNIX system and the Internet. TCP checks for lost packets, puts the data from multiple packets into the correct order, and requests that missing or damaged packets be resent. USB (Universal Serial Bus). A 4-pin serial cable bus that allows up to 127 Plug-n-Play computer peripherals (such as keyboard, mouse, joystick, scanner, printer, modem, and monitor) to share bandwidth through a host scheduled token-based protocols. This allows attaching or detaching while the host and other peripherals are in operation. Supports synchronous and asynchronous transfer types over the same set of wires up to 12Mbit/ sec. USB 2.0 provides 40 times the transfer rate compared to USB 1.0 and competes with the 1394 standard. WAN (Wide Area Network). A geographically dispersed network formed by linking several computers or Local Area Networks (LANs) together over long distances. WANs usually use leased long-distance lines to connect systems across towns, in different cities, or in different regions of the world.
