Chapter 3

This chapter describes the power up sequence and gives information on the BIOS beep codes.

Powering up

Starting up for the first time
1. After making all the connections, replace the system case cover. 2. Be sure that all switches are off. 3. Connect the power cord to the power connector at the back of the system chassis. 4. Connect the power cord to a power outlet that is equipped with a surge protector. 5. Turn on the devices in the following order: a. Monitor b. External SCSI devices (starting with the last device on the chain) c. System power (if you are using an ATX power supply, you need to switch on the power supply as well as press the ATX power switch on the front of the chassis). 6. After applying power, the power LED on the system front panel case lights up. For ATX power supplies, the system LED lights up when you press the ATX power switch. If your monitor complies with green standards or if it has a power standby feature, the monitor LED may light up or switch between orange and green after the system LED turns on. The system then runs the power-on tests. While the tests are running, the BIOS beeps or additional messages appear on the screen. If you do not see anything within 30 seconds from the time you turned on the power, the system may have failed a power-on test. Check the jumper settings and connections or call your retailer for assistance.

Award BIOS Beep Codes

One short beep when displaying logo Long beeps in an endless loop One long beep followed by three short beeps High frequency beeps when system is working

Meaning

No error during POST No DRAM installed or detected Video card not found or video card memory bad CPU overheated; System running at a lower frequency
You will not hear the BIOS beeps when the ASUS POST Reporter is enabled. You will hear the vocal POST messages instead.
7. At power on, hold down <Delete> to enter BIOS Setup. Follow the instructions in Chapter 4. ASUS P4S333 motherboard user guide 3-1

Vocal POST Messages

This motherboard includes the Winbond speech controller to support a special feature called the ASUS POST Reporter. This feature gives you vocal POST messages and alerts to inform you of system events and boot status. In case of a boot failure, you will hear the specific cause of the problem. These POST messages are customizable using the Winbond Voice Editor software that came with your package. You can record your own messages to replace the default messages. Following is a list of the default POST messages and their corresponding actions, if any. POST Message

6. When prompted to confirm the BIOS update, press Y to start the update.
7. The utility starts to program the new BIOS information into the Flash ROM. The boot block is updated automatically only when necessary. This minimizes the possibility of boot problems in case of update failures. When the programming is done, the message Flashed Successfully appears.
8. Follow the onscreen instructions to continue.
If you encounter problems while updating the new BIOS, DO NOT turn off the system because this may cause boot problems. Just repeat the process, and if the problem persists, load the original BIOS file you saved to the boot disk. If the Flash Memory Writer utility is not able to successfully update a complete BIOS file, the system may not boot. If this happens, call the ASUS service center for support.

BIOS Setup program

This motherboard supports a programmable EEPROM 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 of the EEPROM. The EEPROM 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.

Glossary

This part lists the technical terms that you may encounter when reading this document.

ASUS P4B333 motherboard

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.

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.

1.4 Overview

Before you install the P4S333-M motherboard, familiarize yourself with its physical configuration and available features to facilitate the motherboard installation and future upgrades. A sufficient knowledge of the motherboard specifications will also help you avoid mistakes that may damage the board and its components.

When you buy a boxed Intel Pentium 4 478/Northwood Processor, the package includes the heatsink, fan, and retention mechanism. In case you buy a CPU separately, make sure that you use only Intel certified heatsink and fan.
Follow these steps to install the CPU heatsink and fan. 1. Place the heatsink on top of the installed CPU, making sure that the heatsink fits properly on the retention module base.
The retention module base is already installed on the motherboard upon purchase. You do not have to remove the retention module base when installing the CPU or installing other motherboard components.

CPU Heatsink

Retention Module Base
Your boxed Intel Pentium 4 478/Northwood Processor package should come with installation instructions for the CPU, heatsink, and the retention mechanism. If the instructions in this section do not match the CPU documentation, follow the latter.
2. Position the fan with the retention mechanism on top of the heatsink. Align and snap the four hooks of the retention mechanism to the holes on each corner of the module base.
Make sure that the fan and retention mechanism assembly perfectly fits the heatsink and module base, otherwise you cannot snap the hooks into the holes.

Retention Hook Snapped to the Retention Hole
Keep the retention locks lifted upward while fitting the retention mechanism to the module base.
3. Push down the locks on the retention mechanism to secure the heatsink and fan to the module base.
When secure, the retention locks should point to opposite directions.
2.4.4 Connecting the CPU fan cable
When the fan, heatsink, and the retention mechanism are in place, connect the CPU fan cable to the connector on the motherboard labeled CPUFAN1.
CPU Fan Connector (CPUFAN1)
Dont forget to connect the CPU fan connector! Hardware monitoring errors may occur if you fail to plug this connector.

2.5 System memory

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 non-ECC PC2700/2100/1600 DIMMs.

104 Pins

80 Pins
P4S333-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.
DDR Data Transfer Rate 333MHz 266MHz 200MHz DDR Base Frequency 166MHz 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 two DIMM sockets. Use the following combinations to install DDR DIMMs.
DIMM Location Socket 1 (Rows 0&1) Socket 2 (Rows 2&3) 184-pin DDR DIMM 64MB, 128MB, 256MB, 512MB, 1GB 64MB, 128MB, 256MB, 512MB, 1GB Total Memory x1 = x1 = =

2.8 Connectors

This section describes and illustrates the internal connectors on the motherboard.
Some pins are used for connectors or power sources. These are clearly distinguished from jumpers in the Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard. Always connect ribbon cables with the red stripe to Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on floppy disk drives.
1. Hard disk activity LED (2-pin IDELED) This connector supplies power to the hard disk activity LED. The read or write activities of any device connected to the primary or secondary IDE connector cause this LED to light up.
TIP: If the case-mounted LED does not light, try reversing the 2-pin plug.
P4S333-M IDE Activity LED
2. IDE connectors (40-1 pin IDE1 / IDE2) This connector supports the provided UltraDMA/100/66 IDE hard disk ribbon cable. Connect the cables blue connector to the IDE1 (recommended) or the IDE2 connector, then connect the gray connector to the UltraDMA/100/66 slave device (hard disk drive) and the black connector to the UltraDMA/100/66 master device. It is recommended that you connect non-UltraDMA/100/66 devices to the secondary IDE connector. If you install two hard disks, you must configure the second drive as a slave device by setting its jumper accordingly. Refer to the hard disk documentation for the jumper settings. BIOS supports specific device bootup. If you have more than two UltraDMA/100/66 devices, purchase another UltraDMA/100/66 cable. You may configure two hard disks to be both master devices with two ribbon cables one for the primary IDE connector and another for the secondary IDE connector.
1. Pin 20 on each IDE connector is removed to match the covered hole on the UltraDMA cable connector. This prevents incorrect orientation when you connect the cables. 2. The hole near the blue connector on the UltraDMA/100/66 cable is intentional.

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.

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.

4.2.1 BIOS menu bar

The top of the screen has a menu bar with the following selections: MAIN Use this menu to make changes to the basic system configuration.
ADVANCED Use this menu to enable and make changes to the advanced features. POWER BOOT EXIT Use this menu to configure and enable Power Management features.

This field allows you to set the frequency multiple between the CPUs internal frequency (CPU speed) and external frequency. Configuration options: [8x] [10x] [11x]. [21x] [22x] [23x].
CPU/PCI Frequency (MHz) (if CPU Speed is set to [Manual])
This feature expresses the ratio between the CPU and PCI frequency. This setting tells the clock generator what frequency to send to the system bus and PCI bus. The bus frequency (external frequency) multiplied by the bus multiple equals the CPU speed. The setting of this field depends on the CPU Frequency Multiple. Configuration options: [100/33] [101/34]. [165/41] [166/42].
CPU/Memory Frequency Ratio [Auto]
This field determines whether the memory clock frequency is set to be in synchronous or asynchronous mode with respect to the system frequency. The options that appear in the popup menu vary according to the CPU/PCI Frequency (MHz). Configuration options: [Auto] [1:1] [3:4] [3:5] [4:3] [4:5] (The configuration options vary according to the CPU frequency.)
CPU Level 1 Cache, CPU Level 2 Cache [Enabled]
These fields allow you to choose from the default of [Enabled] or choose [Disabled] to turn on or off the CPU Level 1 and Level 2 built-in cache. Configuration options: [Disabled] [Enabled]

BIOS Update [Enabled]

This field functions as an update loader integrated into the BIOS to supply the processor with the required data. When set to [Enabled], the BIOS loads the update on all processors during system bootup. Configuration options: [Disabled] [Enabled]
