2. FEATURES

2.1 The ASUS MES-B Motherboard

The ASUS MES-B motherboard is carefully designed for the demanding PC user who wants many intelligent features in a small package.

2.1.1 Specifications

• Intel Processor Support: Supports Intel’s Celeron processor designed for the

Socket 370 and packaged in Plastic Pin Grid Array (PPGA).

• SiS AGPset: SiS’ 620 AGPset with a built-in 6326 AGP 2X graphics controller supports a 100MHz Front Side Bus (FSB) and UltraDMA/66, which allows burst mode data transfer rates of up to 66.6MBps.

• Enhanced ACPI & Anti-Boot Virus BIOS: Programmable BIOS (Flash

EEPROM), offering enhanced ACPI for Windows 98 compatibility, built-in firmware-based virus protection, and autodetection of most devices for virtually automatic setup.

• Versatile Memory: Equipped with three DIMM sockets to support Intel PC100compliant SDRAMs (up to 768MB).

• Integrated Graphics: Integrated AGP 2X graphics controller can use shared system memory or optional dedicated onboard VGA memory (up to 8MB

SDRAM).

• Onboard Audio (optional): Features an ESS ® Solo-1 PCI audio chipset with

3D surround and positioning capability and integrated audio CODEC.

• Digital Flat Panel Interface (w/optional LCD chip): A direct digital connection is provided for connecting a digital flat panel to your PC. This interface transmits sharp, bright images by eliminating digital-to-analog and analog-todigital conversions, which can accumulate noise and degrade image quality.

• TV Out (w/optional TV Out chip): Supports optional onboard TV out function.

• PCI & ISA Expansion: Provides four 32-bit PCI and two 16-bit ISA expansion slots.

• Wake-On-LAN Connector: Supports Wake-On-LAN activity through an optional Ethernet card (see 7.1 ASUS PCI-L101 Fast Ethernet Card).

• Super Multi-I/O: Provides two high-speed UART compatible serial ports and one parallel port with EPP and ECP capabilities.

• Desktop Management Interface (DMI): Supports DMI through BIOS, which allows hardware to communicate within a standard protocol creating a higher level of compatibility. (Requires DMI-enabled components.)

• IrDA: Supports an optional infrared port module for wireless interface.


2. FEATURES

2.1.2 Performance

• UltraDMA/66 & UltraDMA/33: Comes with an onboard PCI Bus Master IDE controller with two connectors that support four IDE devices on two channels.

Supports UltraDMA/66, UltraDMA/33, PIO Modes 3 & 4 and Bus Master IDE

DMA Mode 2, and Enhanced IDE devices, such as Tape Backup, CD-ROM, CD-

R/RW, and LS-120 drives.

• 66/100MHz Asynchronous & 100/100MHz Synchronous Host/DRAM Clock

Support: CPU frequency can operate at 66MHz or 100MHz while system memory operates at 100MHz or 66MHz. This can optimize the VGA performance under shared memory configuration.

• Double or Quadruple the IDE Transfer Speed: IDE transfers using UltraDMA/

33 Bus Master IDE can handle rates up to 33MB/s and up to 66MB/s using

UltraDMA/66 technology. The best of all is that this new technology is compatible with existing ATA-2 IDE specifications so there is no need to upgrade current IDE devices.

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI master buses to memory to CPU.

• SDRAM Optimized Performance: ASUS smart series motherboards support the new generation memory, Synchronous Dynamic Random Access Memory

(SDRAM), which increases the data transfer rate to 800MB/s max using PC100compliant SDRAM.

• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also implemented on all ASUS smart series motherboards. ACPI provides more Energy

Saving Features for future operating systems (OS) supporting OS Direct Power

Management (OSPM) functionality. With these features implemented in the OS,

PCs can be ready around the clock, yet satisfy all the energy saving standards.

To fully utilize the benefits of ACPI, an ACPI-supported OS, such as Windows

98, must be used.

• PC’98 Compliant: Both the BIOS and hardware levels of the motherboard meets

PC’98 compliancy. The new PC’98 requirements for systems and components are based on the following high-level goals: Support for Plug and Play compatibility and power management for configuring and managing all system components, and 32-bit device drivers and installation procedures for Windows 95/98/NT.


2. FEATURES

2.1.3 Intelligence

• Fan Status Monitoring and Alarm: To prevent system overheat and system damage, the CPU, power supply, and system fans can be monitored for RPM and failure. All the fans are set for its normal RPM range and alarm thresholds.

• Temperature Monitoring and Alert: To prevent system overheat and system damage, this motherboard supports Socket 370 processor thermal sensing.

• Voltage Monitoring and Alert: System voltage levels are monitored to ensure stable current to critical motherboard components. Voltage specifications are more critical for future processors, so monitoring is necessary to ensure proper system configuration and management.

• System Resources Alert: Today’s operating systems such as Windows 95/98/

NT, and OS/2, require much more memory and hard drive space to present enormous user interfaces and run large applications. The system resource monitor will warn the user before the system resources are used up to prevent possible application crashes. Suggestions will give the user information on managing their limited resources more efficiently.

• Auto Fan Off: The system fans will power off automatically even in sleep

mode. This function reduces both energy consumption and system noise, and is an important feature to implement silent PC systems.

• Dual Function Power Button: The system can be in one of two states, one is

Sleep mode and the other is the Soft-Off mode. Pushing the power button for less than 4 seconds places the system into Sleep mode. When the power button is pressed for more than 4 seconds, it enters the Soft-Off mode.

• Remote Ring On (requires modem): This allows a computer to be turned on remotely through an internal or external modem. With this benefit on-hand, any user can access vital information from their computer from anywhere in the world!

• Message LED (requires ACPI OS support): Chassis LEDs now act as information providers. Through the way a particular LED illuminates, the user can determine the stage the computer is in. A simple glimpse provides useful information to the user.

• Keyboard Wake Up: Keyboard Wake Up can be enabled or disabled to allow the computer to be powered ON using your keyboard.

3. HARDWARE SETUP

(This page was intentionally left blank)


3. HARDWARE SETUP

3.3 Hardware Setup Procedure

Before using your computer, you must complete the following steps:

1. Check Motherboard Settings

2. Install Memory Modules

3. Install the Central Processing Unit (CPU)

4. Install Expansion Cards

5. Connect Ribbon Cables, Panel Wires, and Power Supply

3.4 Motherboard Settings

This section explains in detail how to change your motherboard’s function settings through the use of switches and/or jumpers.

WARNING!

Computer motherboards and expansion cards contain very delicate

Integrated Circuit (IC) chips. To protect them against damage from static electricity, you should follow some precautions whenever you work on your computer.

1. Unplug your computer when working on the inside.

2. Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case.

3. Hold components by the edges and try not to touch the IC chips, leads or connectors, or other components.

4. Place components on a grounded antistatic pad or on the bag that came with the component whenever the components are separated from the system.

1) Keyboard Power Up (3-pin KB_UP)

This allows you to disable or enable the keyboard power up function. Set this jumper to Enable if you wish to use your keyboard (by pressing any key or the spacebar depending on your motherboard) to power up your computer. This feature requires an ATX power supply that can supply at least 300mA on the

+5VSB lead. The default is set to Disable because not all computers have the appropriate ATX power supply. Your computer will not power ON if you set this to Enable and do not have the appropriate ATX power supply.

8) CPU External Frequency Setting (SW1-1, SW1-2, SW1-3, SW1-4)

This option tells the clock generator what frequency to send to the CPU, DRAM, and the AGPset. This allows the selection of the CPU’s External frequency. The

CPU external frequency multiplied by the Frequency Multiple equals the CPU’s

Internal frequency (the advertised CPU speed). NOTE: You may set the memory speed independently from the CPU external frequency. Depending on your memory type PC66 (66MHz) or PC100 (100MHz), select the appropriate “RAM” speed along with the appropriate “CPU” speed.

3.5 System Memory (DIMM)

NOTE: No hardware or BIOS setup is required after adding or removing memory.

This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM).

The SiS chipset does not support ECC. However, ECC memory modules may still be used, but the ECC function will not be available.

Memory speed setup is recommended through SDRAM Configuration in 4.4.1

Chip Configuration.

Install memory in any combination as follows:

DIMM Location 168-pin DIMM

Socket 1 (Rows 0&1) SDRAM 8, 16, 32, 64, 128, 256MB

Socket 2 (Rows 2&3) SDRAM 8, 16, 32, 64, 128, 256MB

Socket 3 (Rows 4&5) SDRAM 8, 16, 32, 64, 128, 256MB x1 x1 x1

Total System Memory (Max 768MB) =

Total Memory

NOTE: At the time this User’s Manual was written, 256MB DIMMs are only available as registered memory.

3.5.1 VGA Shared Memory with DIMM

When using DIMM as shared memory for the onboard VGA, be sure that there is a

DIMM inserted into DIMM socket 1.

3.5.2 General DIMM Notes

• For the system CPU bus to operate at 100MHz, use only PC100-compliant

DIMMs. When this motherboard operates at 100MHz, most system will not even boot if non-compliant modules are used because of the strict timing issues involved under this speed. If your DIMMs are not PC100-compliant, set the

CPU external frequency to 66MHz RAM to ensure system stability. NOTE: If your motherboard supports asynchronous mode, set the memory clock frequency to 66MHz.

• ASUS motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of choice for best performance vs. stability.

• SDRAM chips are generally thinner with higher pin density than EDO (Extended Data Output) chips.

• BIOS shows SDRAM memory on bootup screen.


3. HARDWARE SETUP

3.5.3 DIMM Memory Installation

Insert the module(s) as shown. Because the number of pins are different on either side of the breaks, the module will only fit in the orientation as shown. DIMM modules are longer and have different pin contact on each side and therefore have a higher pin density. SIMM modules have the same pin contact on both sides.

3. HARDWARE SETUP

3.6 Central Processing Unit (CPU)

This motherboard provides a ZIF (Zero Insertion Force) Socket 370. The CPU for your motherboard should have a fan attached to it to prevent overheating. If this is not the case, then purchase a fan before you turn on your system.

WARNING!

Be sure that there is sufficient air circulation across the processor’s heatsink by regularly checking that your CPU fan is working. Without sufficient circulation, the processor could overheat and damage both the processor and the motherboard. You may install an auxiliary fan, if necessary.

To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and open it by first pulling the lever sideways away from the socket then upwards to a 90-degree angle. Insert the CPU with the correct orientation as shown.

The notched corner should point towards the end of the lever. Because the CPU has a corner pin for two of the four corners, the CPU will only fit in the orientation as shown. The picture below is for reference only; you should have a CPU fan that covers the face of the CPU. With the added weight of the CPU fan, no force is required to insert the CPU. Once completely inserted, push the socket’s lever down while holding down the CPU.

NOTE: Do not forget to set the correct Bus Frequency and Multiple for your Socket

370 processor or else your system may start. Socket 370 processors provide internal thermal sensing so that a socket mounted thermal resistor is not needed.

CAUTION: Be careful not to scrape the motherboard when mounting a clampstyle processor fan or else damage may occur to the motherboard.

3.7 Expansion Cards

WARNING!

Make sure that you unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards.

3.7.1 Expansion Card Installation Procedure

1. Read the documentation for your expansion card and make any necessary hardware settings for your expansion card, such as jumpers or switches.

2. Remove your computer system’s cover and the bracket plate on the slot you intend to use. Keep the bracket for possible future use.

3. Carefully align the card’s connectors and press firmly.

4. Secure the card on the slot with the screw you removed above.

5. Replace the computer system’s cover.

6. Set up the BIOS if necessary

(such as IRQ xx Used By ISA: Yes)

7. Install the necessary software drivers for your expansion card.

3.7.2 Assigning IRQs for Expansion Cards

Some expansion cards need to use an IRQ to operate. Generally, an IRQ must be exclusively assigned to one use. In a standard design, there are 16 IRQs available but most of them are already in use, leaving 6 IRQs free for expansion cards. If your motherboard has PCI audio onboard, an extra IRQ will be used, leaving 5 IRQs free. If your motherboard has ISA audio onboard, an extra 3 IRQs will be used, leaving 3 IRQs free.

Both ISA and PCI expansion cards may require IRQs. System IRQs are available to cards installed in the ISA expansion bus first, then any remaining IRQs are available to PCI cards. Currently, there are two types of ISA cards.

The original ISA expansion card design, now referred to as “Legacy” ISA cards, requires that you configure the card’s jumpers manually and then install it in any available slot on the ISA bus. To see a map of your used and free IRQs in Windows

98, the Control Panel icon in My Computer, contains a System icon, which gives you a Device Manager tab. Double-clicking on a specific hardware device gives you the Resources tab which shows the Interrupt number and address. Make sure that no two devices use the same IRQ or your computer will experience problems when those two devices are in use at the same time.


3. HARDWARE SETUP

To simplify this process, this motherboard complies with the Plug and Play (PNP) specification, which was developed to allow automatic system configuration whenever a PNP-compliant card is added to the system. For PNP cards, IRQs are assigned automatically from those available.

If the system has both Legacy and PNP ISA cards installed, IRQs are assigned to PNP cards from those not used by Legacy cards. The PCI and PNP configuration of the BIOS setup utility can be used to indicate which IRQs are being used by Legacy cards. For older Legacy cards that do not work with the BIOS, you can contact your vendor for an ISA Configuration Utility.

An IRQ number is automatically assigned to PCI expansion cards after those used by Legacy and PNP ISA cards. In the PCI bus design, the BIOS automatically assigns an IRQ to a PCI slot that has a card in it that requires an IRQ. To install a PCI card, you need to set something called the INT (interrupt) assignment. Since all the

PCI slots on this motherboard use an INTA #, be sure that the jumpers on your PCI cards are set to INT A.

3.7.3 Assigning DMA Channels for ISA Cards

Some ISA cards, both legacy and PnP, may also need to use a DMA (Direct Memory

Access) channel. DMA assignments for this motherboard are handled the same way as the IRQ assignment process described earlier. To select a DMA channel, see PCI/

PNP ISA DMA Resource Exclusion in 4.4.3 PCI Configuration. NOTE: The onboard audio by default uses DMA1.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy ISA cards (see PCI/PNP ISA IRQ Resource Exclusion and PCI/PNP

DMA IRQ Resource Exclusion in 4.4.3 PCI Configuration). Choose Yes in

IRQ xx Used By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

3.7.4 ISA Cards and Hardware Monitor

The integrated hardware monitor uses the address 290H-297H, so legacy ISA cards must not use this address or else conflicts will occur.


3. HARDWARE SETUP

3.8 External Connectors

WARNING!

Some pins are used for connectors or power sources. These are clearly distinguished from jumpers in 3.1 Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard.

IMPORTANT: Ribbon cables should always be connected with the red stripe on

Pin 1 side of the connector. The four corners of the connectors are labeled on the motherboard. Pin 1 is the side closest to the power connector for hard drives and floppy drives. IDE ribbon cables must be less than 46 cm (18 in.), with the second drive connector no more than 15 cm (6 in.) from the first connector.

7) Chassis, CPU , & Power Supply Fan Connectors (3-pin CHA_, CPU_, PWR_FAN)

These connectors support cooling fans of 500mA (6 Watts) or less. Orientate the fans so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan’s plug to the board taking into consideration the polarity of the this connector. NOTE: The “Rotation” signal is to be used only by a specially designed fan with rotation signal.

WARNING!

The CPU and/or motherboard will overheat if there is no airflow across the CPU and onboard heatsinks. Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. These are not jumpers, do not place jumper caps over these pins.

3.9 Power Connection Procedures

1. After all connections are made, close the system case cover.

2. Be sure that all switches are off (in some systems, marked with ).

3. Connect the power supply cord to the power supply located on the back of your system case according to your system user’s manual.

4. Connect the power cord to a power outlet that is equipped with a surge protector.

5. You may then turn on your devices in the following order: a. Your monitor b. External SCSI devices (starting with the last device on the chain) c. Your system power

For ATX power supplies, you need to switch ON the power supply if a switch is provided as well as press the ATX power switch on the front of the case.

6. The power LED on the front panel of the system case will light. For ATX power supplies, the system LED will light when the ATX power switch is pressed. The LED on the monitor may light up or switch between orange and green after the system’s if it complies with “green” standards or if it has a power standby feature. The system will then run power-on tests. While the tests are running, additional messages will appear on the screen. If you do not see anything within 30 seconds from the time you turn on the power, the system may have failed a power-on test. Check your jumper settings and connections again or call your retailer for assistance.

7. During power-on, hold down <Delete> to enter BIOS setup. Follow the instructions in 4. BIOS SETUP.

* Powering Off your computer: You must first exit or shut down your operating system before switching off the power switch. For ATX power supplies, you can press the ATX power switch after exiting or shutting down your operating system. If you use Windows 95/98, click the Start button, click Shut

Down, and then click Shut down the computer?. The power supply should turn off after Windows shuts down.

NOTE: The message “You can now safely turn off your computer” will not appear when shutting down with ATX power supplies.


4.1 Flash Memory Writer Utility

AFLASH.EXE: This is the Flash Memory Writer utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM chip on the motherboard.

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. This file works only in DOS mode.

NOTE: The following screen displays are provided as examples only and may not reflect the screen contents displayed on your system.

40

IMPORTANT: If “unknown” is displayed 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.

4.1.1 Main Menu

1. Save Current BIOS To File

This option allows you to save a copy of the original motherboard BIOS in case you need to reinstall it. It is recommended that you save AFLASH.EXE and the BIOS file to a bootable floppy disk.

4.1.2 Managing and Updating Your BIOS

Upon First Use of the Computer System

1. Create a bootable system floppy disk by typing [FORMAT A:/S] from the DOS prompt.

2. Copy AFLASH.EXE to the just created boot disk.

3. Run AFLASH.EXE from this new disk and select option 1. Save Current

BIOS to File. See 1. Save Current BIOS To File on the previous page for more details and the rest of the steps.

Updating BIOS Procedures (only when necessary)

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

BBS (Bulletin Board Service) (see ASUS CONTACT INFORMATION on page

3 for details) and save to the disk you created earlier.

2. Boot from the disk you created earlier.

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

4. At the Main Menu, type 2 and then press <Enter>. See 2. Update BIOS In-

cluding Boot Block and ESCD on the previous page for more details and the rest of the steps.

WARNING!

If you encounter problems while updating the new BIOS, DO

NOT turn off your system since this might prevent your system from booting up. Just repeat the process, and if the problem still persists, update the original

BIOS file you saved to disk above. If the Flash Memory Writer utility was not able to successfully update a complete BIOS file, your system may not be able to boot up. If this happens, your system will need service.


4. BIOS SETUP

4.2 BIOS Setup Program

This motherboard supports a programmable EEPROM that can be updated using the provided utility as described in 4.1 Flash Memory Writer Utility.

The utility is used if you are installing a motherboard, reconfiguring your system, or prompted to “Run Setup”. This section describes how to configure your system using this utility.

Even if you are not prompted to use the Setup program, at some time in the future you may want to change the configuration of your computer. For example, you may want to enable the Security Password Feature or make changes to the power management settings. It will then be necessary 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 turn on the computer, the system provides you with the opportunity to run this program. This appears during the Power-On Self Test (POST). Press <Delete> to call up the Setup utility. If you are a little bit late pressing the mentioned key(s), POST will continue with its test routines, thus preventing you from calling up Setup. If you still need to call Setup, reset 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 again. But do so only if the first two methods fail.

The Setup program has been 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 various predetermined choices. If you accidentally change a setting and do not know which one to switch back to, the Setup program has a hot key that allows you to return to the previous value. The hot keys are discussed in more detail later in this Section.

To access the BIOS Setup program, press the <Delete> key after the computer has booted through its POST.

NOTE: Because the BIOS software is constantly being updated, the following

BIOS screens and descriptions are for reference purposes only and may not exactly reflect your BIOS screens.

PCI/PNP ISA IRQ Resource Exclusion

58

IRQ XX Used By ISA [No/ICU]

These fields indicate whether or not the displayed IRQ for each field is being used by a legacy (non-PnP) ISA card. The default value indicates either that the displayed IRQ is not used or an ISA Configuration Utility

(ICU) is being used to determine if an ISA card is using that IRQ. If you install a legacy ISA card that requires a unique IRQ, and you are not using an ICU, you must set the field for that IRQ to [Yes]. For example: If you install a legacy ISA card that requires IRQ 10, then set IRQ10 Used By

ISA to [Yes]. Configuration options: [No/ICU] [Yes]


4. BIOS SETUP

PCI/PNP ISA DMA Resource Exclusion

DMA x Used By ISA [No/ICU]

These fields indicate whether or not the displayed DMA channel for each field is being used by a legacy (non-PnP) ISA card. The default setting indicates either that the displayed DMA channel is not used or an ICU is being used to determine if an ISA card is using that channel. If you install a legacy

ISA card that requires a unique DMA channel, and you are not using an

ICU, you must set the field for that channel to [Yes]. Configuration options:

[No/ICU] [Yes]

PCI/PNP ISA UMB Resource Exclusion


4. BIOS SETUP

ISA MEM Block BASE [No/ICU]

If this menu item is set to [Disabled], power management features will not function regardless of other field settings on this menu. The [User Define] option allows you to make your own selections in the Power menu. When set to [Max Saving], system power will be conserved to its greatest amount. The Doze Mode, Standby Mode, and Suspend

Mode fields will then be set to predefined values that ensure maximum power savings.

This field acts as the master control for the power management modes. [Max Saving] puts the system into power saving mode after a brief period of system inactivity; [Min

Saving] is almost the same as [Max Saving] except that this time the system inactivity period is longer; [Disabled] disables the power saving features; [User Define] allows you to set power saving options according to your preference. Configuration options:

[User Define] [Disabled] [Min Saving] [Max Saving]

IMPORTANT: Advanced Power Management (APM) should be installed to keep the system time updated when the computer enters suspend mode activated by the BIOS Power Management. For DOS environments, you need to add the statement, DEVICE=C:\DOS\POWER.EXE, in you CONFIG.SYS. For Windows 3.x and Windows 95, you need to install Windows with the APM feature.

For Windows 98 and later, APM is automatically installed. A battery and power cord icon labeled “Power” will appear in the “Control Panel.” Choose “Advanced” in the Power Management Field.

.RMI formats). With the multisource Audio Mixer, you can blend these sources with line-in and microphone sources any way you choose. You can then record your creations as wave files and edit them with the Audio Recorder.

The AudioRack32 has six main parts:

• Command Center—customizes the appearance of the AudioRack32.

• 3-D/Tone Controller—gives your computer ambiient 3D sound, transmitting any sound played through the AudioRack32 into a wider arc.

• Audio Mixer—controls the volume and balance of the AudioRack32 devices.

• Digital Audio Player—plays and records files in the .WAV format.

• MIDI Player—enables you to play MIDI files.

• Compact Disk Player—enables you to play audio CDs on a CD-ROM drive.

In addition, the AudioRack32 has a miniature mode enabling you to control the

AudioRack32 while using minimal screen space.

The Audio Recorder is a separate application from the AudioRack32. It can be used to add effects and edit files recorded with the Digital Audio Player or by the Audio

Recorder itself. The Audio Recorder can be launched from the AudioRack32’s Digital

Audio Player or on its own.

You can use these two modes to fully control which of your audio sources you are listening to or recording, how loud each of those sources are and how they are balanced. Each audio source has its own module with mute, balance and volume controls.

In addition, the Audio Mixer provides special effects controls for chorus, reverb, treble, bass, and 3-D effects.

The Audio Mixer Controls

The two Playback and Record toggle buttons are used to switch between Playback mode and Record mode.

The Effects toggle button switches the display to the effects panel where you can use the buttons to enable and disable effects and the sliders to control the amount of the effect.

There are a number of audio source modules displayed on the Audio Mixer. The exact number displayed depends on the capabilities of your hardware. Each module has three controls: a slider to adjust the balance a slider to adjust the volume a button for muting

Modules that your hardware may provide for are: Master, Line, Wave, Mic, CD,

MIDI, and Aux B.



6.2.5 The Digital Audio Player

The Digital Audio Player enables you to play, record, and compress sound as .WAV

files. In addition, you can play .AUD files. The .WAV files use PCM, which is the

Windows‘ audio file format. The.AUD format uses ESPCM‘ compression to produce an audio file. Files are written directly to your hard disk as you record, enabling you to record very large files. Your only limitation is the amount of free space on your hard disk. The voice activation feature is useful for recording any kind of intermittent audio. The Digital Audio Player provides a choice of linear PCM (8 or

16 bit) recording. Note that you have additional options using the Audio Recorder, which is invoked by the Edit button.

The display tells you the file name, size, number of bits per sample, sample rate, and whether the file was recorded in stereo or mono. Click again to return to the image of the tape deck.



6.2.6 The MIDI Player

The MIDI Player enables you to play MIDI files with the .MID or .RMI file extensions. These MIDI (Musical Instrument Digital Interface) files can be produced by sequencer programs and then played back using the MIDI Player. You can also mix

MIDI files with other audio sources. Or you can compile MIDI files in a playlist and play them back in any order you choose.

The MIDI Player Display

By clicking on the image of the floppy drive, you can display the length and name of the current MIDI file in the playlist. Click the display to return to the image of the floppy drive.

The MIDI Player has an indicator to show when you are listening to

ESFM. When the ESFM light to the left of the playlist button is lit, the MIDI Player is using ESFM synthesis. ESFM performs superior-quality music synthesis compared to that of traditional FM, producing richer timbre and greater depth of instrument voices. FM synthesis is a lower quality technology compared with Wave table synthesis. This card supports Wave table synthesis therefore ESFM is not supported on this card.



6.2.7 The Compact Disk Player

If you have a CD-ROM drive, you can play audio CDs. Check your hardware manual about setting up CD audio hardware and drivers. The Compact Disk Player uses intelligent CD playlist management: The Compact Disk Player maintains a record of each CD you play. It remembers the last playlist you used with each CD and loads that playlist automatically whenever you insert that CD.

6.2.8 The Audio Recorder

The Audio Recorder enables you to record, compress, store, and play back voice, music, and other sound. It provides settings for sound attributes such as mono/stereo, compression level, and sampling rate. You can use it to embed sound objects in documents created in applications that support object linking and embedding (OLE).

The Audio Recorder’s edit, record, and playback capabilities are compatible with the Windows Sound Recorder and other recorders that record and play back in the

PCM format. Like the Digital Audio Player, the Audio Recorder can record and play back .WAV and .AUD files. The Audio Recorder allows a choice of compression from low, medium, and high ESPCM and ADPCM.

6.2.9 Release Notes

This information is provided for convenience only. Information here is subject to change without prior notice. View the installation CD for any updated information in Readme text files. The AudioRack also provides detailed online help (click the

Help button on the “Command Center”)

Disable Eject Button on the CD Player

Under the Windows directory in the file “auddrive.ini”, there is a string

“DisableEjectButton=0” under the [cdplayer] section. If you would like to disable

EJECT button on the CD player, you can change the value from 0 to 1. You need to close AudioRack and launch it again to make the new settings take effect.

Using AudioRack CD Player as Default CD Player

During installation, you will be asked if you want to use AudioRack CD player as the default CD player. Normally Windows 95 CD player is the default and will automatically run when an audio CD is inserted into the CD-ROM. If you answer

“Yes”, the installation program will overwrite the value of the key

[HKEY_CLASSES_ROOT]\AudioCD\shell\play\command in the registry. You may switch back to Windows 95 CD player by resetting this key value.

Configuring Playback Mixer

The PCI audio chip offers eight inputs for the playback mixer, including “Line”,

“Wave”, “CD”, “Synth”, “Aux A”, “Aux B”, “Mic”, and “Mono In”. AudioRack can only display six of them at a time. You may configure the settings by modifying the file “auddrive.ini” in the Windows directory. Under the section [MixerRak], you can enable or disable the display of each input by setting its corresponding binary value to 1 (enable) or 0 (disable).



6.3 Desktop Management Interface (DMI)

6.3.1 Introducing the ASUS DMI Configuration Utility

This motherboard supports DMI within the BIOS level and provides a DMI Configuration Utility to maintain the Management Information Format Database (MIFD).

DMI is able to auto-detect and record information pertinent to a computer’s system such as the CPU type, CPU speed, and internal/external frequencies, and memory size. The onboard BIOS will detect as many system information as possible and store those collected information in a 4KB block in the motherboard’s Flash EPROM and allow the DMI to retrieve data from this database. Unlike other BIOS software, the BIOS on this motherboard uses the same technology implemented for Plug and

Play to allow dynamic real-time updating of DMI information versus creating a new

BIOS image file and requiring the user to update the whole BIOS. This DMI Configuration Utility also allows the system integrator or end user to add additional information into the MIFD such as serial numbers, housing configurations, and vendor information. Those information not detected by the motherboard BIOS and has to be manually entered through the DMI Configuration Utility and updated into the

MIFD. This DMI Configuration Utility provides the same reliability as PnP updating and will prevent the refreshing failures associated with updating the entire BIOS.

6.3.2 Starting the ASUS DMI Configuration Utility

The DMI Configuration Utility (DMICFG2.EXE) must be used in real mode in order for the program to run, the base memory must be at least 180K. Memory managers like HIMEM.SYS (required by windows) must not be installed. You can boot up from a system diskette without AUTOEXEC.BAT and CONFIG.SYS files,

“REM” HIMEM.SYS in the CONFIG.SYS, or press <Shift>+<F5> during bootup to bypass your AUTOEXEC.BAT and CONFIG.SYS files.

1. In Windows, copy DMICFG2.EXE to your hard disk drive.

2. Restart your computer and press <Shift>+<F5> during bootup to enter safe mode command prompt.

3. Go to the directory containing DMICFG2.EXE.

4. Type DMICFG2 and press <Enter> to run.



6.3.3 Using the ASUS DMI Configuration Utility
