Special features

1.4.1 Product highlights

Latest processor technology

The P4B-E motherboard supports the latest Intel Pentium 4 478/

Northwood Processor, also known as P4, via a 478-pin surface mount ZIF socket. The Pentium 4 processor utilizes the advanced 0.18 micron processor core in FC-PGA2 package for a 2.0GHz frequency, while the

Northwood processor uses the 0.13 micron processor core with 512KB L2 cache for up to a speedy 2.4GHz frequency. The P4 offers optimized performance for audio, video, and Internet applications.

ASUS POST Reporter™

P4B-E offers a new exciting feature called the ASUS POST Reporter™ to provide friendly voice messages and alerts during the Power-On Self-Tests

(POST). Through the system’s internal speaker, or an added external speaker, you will hear the messages informing you of the system boot status and causes of boot errors, if any. The bundled Winbond Voice

Editor software allows you to customize the voice messages, and provides multi-language support.


ASUS EZ Plug™

This patented ASUS technology lets you use your existing power supply rather than buying a new ATX 12V power supply. The ASUS EZ Plug™ is a 4-pin auxillary +12V connector mounted on the motherboard that connects a regular 4-pin device power connector from the power supply.

This connector is necessary to provide the additional power required by the P4 CPU.

ASUS MyLogo™

This new feature present in the P4B-E motherboard allows you to personalize and add style to your system using customizable boot logos.

Digital audio interface

On audio models, a digital audio connector is onboard to accommodate the bundled Sony-Philips Digital Interface (SPDIF) In/Out module, which supports coaxial and optical interfaces. Experience 5.1-channel surround sound and enhanced 3D audio while playing your favorite DVDs and computer games.

RAID 0/RAID 1 support

The motherboard includes the Promise ® chip PDC20265R and two extra

Ultra ATA/100/66 interfaces to support Redundant Array of Independent

Disks (RAID) configuration. This feature requires UltraATA 100/66/33 hard disks. The RAID chip onboard supports RAID 0 and RAID 1 configurations.

RAID 0 (called data striping) optimizes two identical hard disk drives to read and write data in parallel, interleaved stacks. Two hard disks perform the same work as a single drive but at a sustained data transfer rate, double that of a single disk alone, thus improving data access and storage. RAID 1 (called data mirroring) copies and maintains an identical image of data from one drive to a second drive. If one drive fails, the disk array management software directs all applications to the surviving drive as it contains a complete copy of the data in the other drive. This RAID configuration provides data protection and increases fault tolerance to the entire system.

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.

When lit, the green LED (LED1) indicates that the system is ON, in sleep mode, or in soft-off mode, a reminder that you should shut down the system before removing of plugging in any motherboard component.

The red LED (LED2) is a smart protection from motherboard burn out caused by an incorrect AGP card. If you plug in any 3.3V AGP card into the 1.5V AGP slot, this LED lights up thus preventing the system to power up. This LED remains off if you plug in a 1.5V AGP card.

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 six 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.

Figure 2-18 Installed PCI Card

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 (LED2) 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!

2.6.5 CNR slot

The Communications and Networking Riser (CNR) slot supports interface cards that integrates audio, modem, and network functionality.

The CNR specification supports interfaces including:

• Audio Codec ‘97 (AC ’97) - for audio and/or modem functions

• Local Area Network (LAN) - for networking functions

• Universal Serial Bus (USB) - for functions implemented in the USB interface, and technologies such as broadband, DSL, and wireless

• System Management Bus (SMB) - for Plug-n-Play functionality

• Power - to provide the signals required for power management, and the main power supplies to operate the CNR circuitry

The CNR is tagged to replace the current Audio Modem Riser (AMR) slot because of its flexibility and added features. Also, the CNR slot does not take up the motherboard space for one PCI slot because it is a shared slot; rather, it provides you more options.

4. USB device wake-up (3-pin USBPWR01, USBPWR23)

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 USBPWR01 jumper is for the rear USB ports. The USBPWR23 jumper is for the internal USB header that you can connect to the front

USB ports.

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.

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 HDLED)

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.

2. Primary/Secondary IDE connectors (40-1 pin IDE1/IDE2)

This connector supports the provided UltraATA/100/66/33 IDE hard disk ribbon cable. Connect the cable’s blue connector to the primary

(recommended) or secondary IDE connector, then connect the gray connector to the UltraATA/100/66/33 slave device (hard disk drive) and the black connector to the UltraATA/100/66/33 master device. It is recommended that you connect non-UltraATA/100/66/33 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 UltraATA/100/66/33 devices, purchase another UltraATA/100/66/33 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

Chapter 4


4.1

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>.

4-2 Chapter 4: BIOS Setup

4.1.2 Updating BIOS procedures

Update the BIOS only if you have problems with the motherboard and you are sure that the new BIOS revision will solve your problems.

Careless updating may result to more problems with the motherboard!

1. Download an updated ASUS BIOS file from the Internet (WWW or

FTP) (see ASUS CONTACT INFORMATION on page x for details) and save to the boot floppy disk you created earlier.

2. Boot from the floppy disk.

3. At the “A:\” prompt, type AFLASH and then press <Enter>.

4. At the Main Menu, type 2 then press <Enter>. The Update BIOS

Including Boot Block and ESCD screen appears.

5. Type the filename of your new BIOS and the path, for example,

A:\XXX-XX.XXX, then press <Enter>.

To cancel this operation, press <Enter>.

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.

4-4

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.

Chapter 4: BIOS Setup

4.2

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.

5.3.3 Personalized Boot Logo

Also included in the support CD is a DOS version of ASUS MyLogo™.

Locate the application called LOGO.EXE and a sample image library of boot screens in bitmap (BMP) format to install this feature.

Back up your system BIOS to a bootable floppy disk before using

LOGO.EXE to modify your boot screen. See section “4.1 Managing and updating your BIOS”.

Make sure that the item Full Screen Logo in BIOS is set to [Enabled].

1. To set up a new Personalized Boot Logo, browse the Support CD and copy these three components to the windows directory: LOGO.EXE;

AFLASH.EXE; one or more BMP files in 640 x 480 pixel, 16-color format.

Follow these steps to customize your POST messages.

1. Launch the Voice Editor and take note of the list of POST events on the leftmost column of the screen.

2. Prepare your message for each event.

The total compressed size for all the wave files must not exceed 1Mbit, so make your messages as short as possible.

3. Use a recording software, such as Windows Recorder, to record your messages.

4. Save the messages as wave files (.WAV). It is recommended that you save your files in low quality to keep them small. For example, use

8-bit, mono quality at 22Khz sampling rate.

You may want to create a separate folder for your wave files so you can locate them easily in one place.

5. From the Voice Editor screen, click on the Add button to display the Add Wave File window.
