II. FEATURES

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

• Quick Adjustments: Easy-to-access DIP switches make changing CPU and

onboard function settings a snap.

Introduction to ASUS Smart Series Motherboards

Performance

• ACPI Ready: ACPI (Advanced Configuration and Power Interface) is also imple-

mented on all ASUS smart series motherboards. ACPI provides more Energy
Saving Features for future operating systems (OS) supporting OS Direct Power
Management (OSPM) functionality . W ith these features implemented in the OS,
PCs can be ready around the clock, yet satisfy all the energy saving standards.
T o fully utilize the benefits of ACPI, an ACPI-supported OS such as the succes­sor of Windows 95 must be used.

• Double the IDE Transfer Speed: IDE transfers using UltraDMA/33 Bus Mas-

ter IDE can handle rates up to 33MB/sec. The best of all is that this new technol­ogy is compatible with existing AT A-2 IDE specifications so there is no need to
upgrade current hard drives or cables.

Smart Series

II. FEATURES

• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-

ter buses to memory to CPU.

• 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.

• 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 PC100
SDRAM.

ASUS MEZ User’s Manual 9

II. FEATURES

Smart Series

II. FEATURES

Intelligence (some features require the optional Hardware/Thermal Monitor)

• 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, there are heat sensors to monitor the CPU and system temperatures to
warn of damaging temperatures.

• 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: T oday’ s operating systems such as W indows 95, W in-

dows 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 Power Up: Keyboard Power Up can be enabled or disabled to allow
the computer to be powered on by pressing the space bar on the keyboard.

• Chassis Intrusion Detection: Supports chassis-intrusion monitoring through the
optional ASUS CIDB chassis intrusion sensor module (See APPENDIX) and
LDCM.

Motherboard Settings

III. H/W SETUP

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 o r
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.

III. HARDWARE SETUP

1. Keyboard Power Up (3-pin KBPWR)

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 the spacebar) to
power up your computer. This feature requires an ATX power supply that can
supply at least 300mAmp 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 if you do not have the right
ATX power supply.

2. 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 Ac-
cess Memory (SDRAM) of either 8, 16, 32, 64, 128MB, or 256MB.

The Intel 440ZX AGPset does not support ECC function. ECC memory modules
may be used but the ECC function will not be available.

Memory speed setup is recommended through SDRAM Configuration under “Chipset
Features Setup” in BIOS SETUP.

Install memory in the following combinations:

Location 168-pin DIMM SDRAM Total Memory

DIMM1 Single-sided x1
(Rows 0&1) Double-sided

DIMM2 Single-sided x1
(Rows 2&3) Double-sided (Socket 3 must be empty)

DIMM3 Single-sided (Socket 2 must be single-sided) x1
(Row 3) (Double-sided cannot be used here!)

Total System Memory (Max 256MB) =

IMPORTANT! A total of four rows of memory is supported on this motherboard.

One side (with memory chips) of the DIMM takes up one row . Because Socket 3
shares Row 3 with Socket 2, Socket 3 can only be used if Socket 2 does not use
Row 3.

WARNING! If Row 3 is used by both Socket 2 and 3, your system will not boot up!

SPD Support

This motherboard supports SPD DIMMs, and it is recommended that SPD DIMMs
be used.

General DIMM Notes

• For the system CPU bus to operate above 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 bus frequency to 66MHz for system stability.

• Two possible memory chips are supported: SDRAM with and without ECC.

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

• BIOS shows SDRAM memory on bootup screen.

• 8 chips/side modules do not support ECC, only 9 chips/side modules support ECC.

• Single-sided DIMMs come in 16, 32, 64,128MB; double-sided come in 32, 64,
128, 256MB.

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. Central Processing Unit (CPU)

The motherboard provides a ZIF Socket 370. The CPU that came with the 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. W ithout suf ficient
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 right angle. Insert the CPU with the correct orientation as
shown. The notched corner should point towards the end the of the lever. Because
the CPU has a corner pin for two of the four corners, the CPU will only fit in the one
orientation as shown. The picture is for reference only; you should have a CPU fan
that will cover the face of the CPU. W ith the added weight of the CPU fan, no force
is required to insert the CPU. Once completely inserted, close the socket’s lever
while holding down the CPU.

4. 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.

Expansion Card Installation Procedure

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

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 in PNP AND PCI SETUP)

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

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.

NOTE: The onboard audio shares an IRQ with PCI slot 2.
Both ISA and PCI expansion cards may require to use IRQs. System IRQs are avail-

able 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. You may use the Microsoft Diagnostics (MSD.EXE) utility located in the Win­dows directory to see a map of your used and free IRQs. If you use W indows 95, the
Resources tab under Device Manager displays the resource settings being used by
a particular device (to gain access, double-click the System icon under the Control
Panel program). Ensure that no two devices share the same IRQs or your computer
will experience problems when those two devices are in use at the same time.

III. H/W SETUP

Expansion Cards

ASUS MEZ User’s Manual 21

T o simplify this process this motherboard has complied 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 does 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.

Expansion Cards

III. H/W SETUP

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. You can select a DMA channel in
the PCI and PnP configuration section of the BIOS Setup utility.

III. HARDWARE SETUP

NOTE: The onboard audio by default uses DMA1.

IMPORTANT: To avoid conflicts, reserve the necessary IRQs and DMAs for legacy

ISA cards (under PNP AND PCI SETUP of BIOS SETUP, choose Yes in IRQ xx Used
By ISA and DMA x Used By ISA for those IRQs and DMAs you want to reserve).

ISA Cards and Hardware Monitor

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

Updating BIOS

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.

ASUS MEZ User’s Manual38

IV. BIOS SETUP

6. BIOS Setup

The motherboard supports two programmable Flash ROM chips: 5-Volt and 12­Volt. Either of these memory chips can be updated when BIOS upgrades are re­leased. Use the Flash Memory W riter utility to download the new BIOS file into the
ROM chip as described in detail in this section.

All computer motherboards provide a Setup utility program for specifying the sys­tem configuration and settings. If your motherboard came in a computer system, the
proper configuration entries may have already been made. If so, invoke the Setup
utility , as described later , and take note of the configuration settings for future refer ­ence; in particular, the hard disk specifications.

If you are installing the motherboard, reconfiguring your system or you receive a
Run Setup message, you will need to enter new setup information. This section
describes how to configure your system using this utility.

The BIOS ROM of the system 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 case. You can also restart by turning the system off
and then back on again. But do so only if the first two methods fail.

When you invoke Setup, the CMOS SETUP UTILITY main program screen will
appear with the following options:

A section at the bottom of the above screen displays the control keys for this screen.
T ake note of these keys and their respective uses. Another section just below the con­trol keys section displays information on the currently highlighted item in the list.

Standard CMOS Setup

The “Standard CMOS Setup” option allows you to record some basic system hard­ware configuration and set the system clock and error handling. If the motherboard
is already installed in a working system, you will not need to select this option
anymore. However, if the configuration stored in the CMOS memory on the board
gets lost or damaged, or if you change your system hardware configuration, you will
need to respecify the configuration values. The configuration values usually get lost
or corrupted when the power of the onboard CMOS battery weakens.

Hard Disks

This field records the specifications for all non-SCSI hard disk drives installed in
your system. The onboard PCI IDE connectors provide Primary and Secondary chan­nels for connecting up to four IDE hard disks or other IDE devices. Each channel
can support up to two hard disks; the first of which is the “master” and the second is
the “slave”.

Specifications for SCSI hard disks need not to be entered here since they operate
using device drivers and are not supported by the BIOS. If you install other SCSI
controller cards, refer to their respective documentations on how to install the re­quired SCSI drivers.

For IDE hard disk drive setup, you can:

• Use the Auto setting for detection during bootup.

• Use the IDE HDD AUTO DETECTION in the main menu to automatically
enter the drive specifications.

• Enter the specifications yourself manually by using the “User” option.

The entries for specifying the hard disk type include CYLS (number of cylinders),
HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ
(landing zone), SECTOR (number of sectors) and MODE. The SIZE field auto­matically adjusts according to the configuration you specify. The documentation
that comes with your hard disk should provide you with the information regarding
the drive specifications.

The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI
drives. This entry provides three options: Normal, Lar ge, LBA, or Auto (see below).
Set MODE to the Normal for IDE hard disk drives smaller than 528MB; set it to
LBA for drives over 528MB that support Logical Block Addressing (LBA) to allow
larger IDE hard disks; set it to Large for drives over 528MB that do not support
LBA. Large type of drive can only be used with MS-DOS and is very uncommon.
Most IDE drives over 528MB support the LBA mode.

Auto detection of hard disks on bootup

For each field: Primary Master, Primary Slave, Secondary Master, and Secondary
Slave, you can select Auto under the TYPE and MODE fields. This will enable auto
detection of your IDE hard disk during bootup. This will allow you to change your
hard disks (with the power off) and then power on without having to reconfigure
your hard disk type. If you use older hard disks that do not support this feature, then
you must configure the hard disk in the standard method as described earlier by the
“User” option.

NOTE: After the IDE hard disk drive information has been entered into BIOS, new
IDE hard disk drives must be partitioned (such as with FDISK) and then formatted
before data can be read from and write on. Primary IDE hard disk drives must have
its partition set to active (also possible with FDISK).

NOTE: SETUP Defaults are noted in parenthesis next to each function heading.

Boot Virus Detection (Enabled)

This field allows you to set boot virus detection, ensuring a virus-free boot sector.
This new antivirus solution is unlike native BIOS tools, which offer limited virus
protection typically by write-protecting the partition table. With this new solution,
your computer is protected against boot virus threats earlier in the boot cycle, that is,
before they have a chance to load into your system. This ensures your computer
boots to a clean operating system. The system halts and displays a warning message
when it detects a virus. If this occurs, you can either allow the operation to continue
or use a virus-free bootable floppy disk to restart and investigate your system. Be­cause of conflicts with new operating systems, for example, during installation of
new software, you may have to set this to Disabled to prevent write errors.

complete test of the system is done on each test.

HDD Sequence SCSI/IDE First (IDE)

When using both SCSI and IDE hard disk drives, IDE is always the boot disk using
drive letter C (default setting of IDE). This new feature allows a SCSI hard disk
drive to be the boot disk when set to SCSI. This allows multiple operating systems
to be used on both IDE and SCSI drives or the primary operating system to boot
using a SCSI hard disk drive.

are A,C; C,A; A,CDROM,C; CDROM,C,A; D,A; E,A; F,A; C only; LS/ZIP, C; LAN,A,C;
and LAN,C,A. The setup default setting, A, C, is to check first the floppy disk and then
the hard disk drive.

Boot Up Floppy Seek (Disabled)

When enabled, the BIOS will seek drive A once.

Floppy Disk Access Control (R/W)

This allows protection of files from the computer system to be copied to floppy
disks by allowing the setting of Read Only to only allow reads from the floppy disk
drive but not writes. The setup default R/W allows both reads and writes.

IDE HDD Block Mode Sectors (HDD MAX)

This field enhances hard disk performance by making multi-sector transfers instead
of one sector per transfer. Most IDE drives, except older versions, can utilize this
feature. Selections are HDD MAX, Disabled, 2, 4, 8, 16, and 32.

HDD S.M.A.R.T. capability (Disabled)

This allows the enabling or disabling of the S.M.A.R.T. (Self-Monitoring, Analysis

PS/2 Mouse Function Control (Auto)

The default of Auto allows the system to detect a PS/2 mouse on bootup. If detected,
IRQ12 will be used for the PS/2 mouse. IRQ12 will be reserved for expansion cards
if a PS/2 mouse is not detected. Enabled will always reserve IRQ12, whether on
bootup a PS/2 mouse is detected or not.

OS/2 Onboard Memory > 64M (Disabled)

When using OS/2 operating systems with installed DRAM of greater than 64MB,
you need to set this option to Enabled otherwise leave this on Disabled.

PCI/VGA Palette Snoop (Disabled)

Some display cards that are nonstandard VGA such as graphics accelerators or MPEG
V ideo Cards may not show colors properly . The setting Enabled should correct this
problem. Otherwise leave this on the setup default setting of Disabled.

Video ROM BIOS Shadow (Enabled)

This field allows you to change the video BIOS location from ROM to RAM. Relo­cating to RAM enhances system performance, as information access is faster than
the ROM.

C8000-CBFFF to DC000-DFFFF (Disabled)

These fields are used for shadowing other expansion card ROMs. If you install
other expansion cards with ROMs on them, you will need to know which addresses
the ROMs use to shadow them specifically . Shadowing a ROM reduces the memory
available between 640K and 1024K by the amount used for this purpose.

Boot Up NumLock Status (On)

This field enables users to activate the Number Lock function upon system boot.

Typematic Rate Setting (Disabled)

When enabled, you can set the two typematic controls listed next. Setup default

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.

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. A vailable options include: No/ICU and
Yes. The first option, 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.

ISA MEM Block BASE (No/ICU)

This field allows you to set the base address and block size of a legacy ISA card that
uses any memory segment within the C800H and DFFFH address range. If you
have such a card, and you are not using an ICU to specify its address range, select a
base address from the six available options; the ISA MEM Block SIZE field will
then appear for selecting the block size. If you have more than one legacy ISA card
in your system that requires to use this address range, you can increase the block
size to either 8K, 16K, 36K, or 64K. If you are using an ICU to accomplish this task,
leave ISA MEM Block BASE to its default setting of No/ICU.

Symbios SCSI BIOS (Auto)

Auto allows the BIOS to detect whether you have a Symbios SCSI card, if detected
the onboard Symbios BIOS will be enabled, if not then it will be disabled. Disabled
prevents the onboard Symbios BIOS to be enabled so that the external Symbios
SCSI card’ s own BIOS can be used instead. Note: If your Symbios SCSI card does
not have a BIOS, the Symbios SCSI card will not function.

USB IRQ (Enabled)

Enabled reserves an IRQ# for the USB to work, Disabled does not allow the USB to
have an IRQ# and therefore prevents the USB from functioning. If you are not using
any USB devices, you may set this feature to Disabled to save an extra IRQ# for
expansion cards.

VGA BIOS Sequence (PCI/AGP)

You can select the search order for your VGA card(s). PCI/AGP will detect PCI
VGA cards before AGP, and AGP/PCI will detect AGP cards before PCI VGA.

Supervisor Password and User Password

These two options set the system passwords. “Supervisor Password” sets a pass­word that will be used to protect the system and the Setup utility; “User Password”
sets a password that will be used exclusively on the system. By default, the system
comes without any passwords. To specify a password, highlight the type you want
and then press <Enter>. A password prompt appears on the screen. Taking note that
the password is case sensitive, and can be up to 8 alphanumeric characters long, type
in your password and then press <Enter>. The system confirms your password by
asking you to type it again. After setting a password, the screen automatically re­verts to the main screen.

To implement password protection, specify in the “Security Option” field of the
BIOS Features Setup screen when the system will prompt for the password. If you
want to disable either password, press <Enter> instead of entering a new password
when the “Enter Password” prompt appears. A message confirms the password has
been disabled.

Forgot the password?

If you forgot the password, you can clear the password by erasing the CMOS Real
Time Clock (RTC) RAM. The RAM data containing the password information is
powered by the onboard button cell battery. To erase the RTC RAM: (1) Unplug
your computer, (2) Short the solder points, (3) Turn ON your computer, (4) Hold
down <Delete> during bootup and enter BIOS setup to re-enter user preferences.

IDE HDD Auto Detection

The “IDE HDD Auto Detection” option detects the parameters of an IDE hard disk
drive, and automatically enters them into the Standard CMOS Setup screen.

Up to four IDE drives can be detected, with parameters for each listed inside the
box. To accept the optimal entries, press <Y> or else select from the numbers dis­played under the OPTIONS field (2, 1, 3 in this case); to skip to the next drive, press
<N>. If you accept the values, the parameters will appear listed beside the drive
letter on the screen. The process then proceeds to the next drive letter. Pressing

IV. BIOS SETUP

Hard Disk Detect

<N> to skip rather than to accept a set of parameters causes the program to enter
zeros after that drive letter.

Remember that if you are using another IDE controller that does not feature En­hanced IDE support for four devices, you can only install two IDE hard disk drives.
Your IDE controller must support the Enhanced IDE features in order to use Drive E
and Drive F. The onboard PCI IDE controller supports Enhanced IDE, with two
connectors for connecting up to four IDE devices. If you want to use another con­troller that supports four drives, you must disable the onboard IDE controller in the
Chipset Features Setup screen.

When auto-detection is completed, the program automatically enters all entries you
accepted on the field for that drive in the Standard CMOS Setup screen. Skipped
entries are ignored and are not entered in the screen.

If you are auto-detecting a hard disk that supports the LBA mode, three lines will
appear in the parameter box. Choose the line that lists LBA for an LBA drive. Do
not select Large or Normal.

The auto-detection feature can only detect one set of parameters for a particular IDE
hard drive. Some IDE drives can use more than one set. This is not a problem if the
drive is new and empty.

ASUS MEZ User’s Manual56

IV. BIOS SETUP

IMPORTANT: If your hard disk was already formatted on an older previous system,
incorrect parameters may be detected. You will need to enter the correct parameters
manually or use low-level format if you do not need the data stored on the hard disk.

If the parameters listed differ from the ones used when the disk was formatted, the
disk will not be readable. If the auto-detected parameters do not match the ones that
should be used for your disk, do not accept them. Press <N> to reject the presented
settings and enter the correct ones manually from the Standard CMOS Setup screen.

Save & Exit Setup

Select this option to save into the CMOS memory all modifications you specified
during the current session. To save the configuration changes, highlight the “Save

Exit Without Saving

Select this option to exit the Setup utility without saving the modifications you specify
during the current session. To exit without saving, highlight the “Exit W ithout Sav­ing” option on the main screen and then press <Enter>.

The AudioRack32 enables you to take advantage of your computer’s audio capabili-
ties with all of the controls conveniently in one compact space. You can play audio
CDs, wave files (in WAV and .AUD formats), and MIDI files (in.MID and .RMI
formats). W ith the multisource Audio Mixer, you can blend these sources with line­in 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.

• 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.

Intel LANDesk Client Manager

Intel LDCM

With the growth of the computer industry, computer systems have become more
complex and difficult to manage. Intel LANDesk Client Manager is a computer
management application that simplifies many aspects of managing a computer and
assists in troubleshooting common computer problems.

Use Client Manager to:

• Review system inventory

• View DMI-compliant component information

• Backup and restore system files

• Troubleshoot

• Monitor your computer’s health

• Receive notifications for system events

Client Manager has been implemented in two different ways:

VI. SOFTWARE REFERENCE

The client version enables you to view information and manage alerts for a local
computer. This version does not permit you to select remote computers, transfer
files, or reboot other computers.

The first time you run Client Manager, it searches your network for other computers
running Client Manager . Client Manager creates a list of the computers it finds and
saves the list to the Windows registry. From this point on, when you run Client
Manager or open the Select Computer dialog box, Client Manager checks to see if
these computers (listed in the registry) are available and healthy.

After you attempt to wake up a computer, the status of that computer changes in the
list view to a Wake Pending status. If the attempt to wake up a computer is success­ful, the Wake Pending status changes to a status reflecting the computer’s health
(such as Normal, Warning, or Critical). If the computer does not wake up after five
minutes, a message box appears stating possible reasons why the computer did not
respond. (For example, the computer may be disabled or may not support W ake-On­LAN.) After clicking OK, the Wake Pending status reverts to its original status of
Unavailable or Wakeable.

NOTE: You computer must have a Wake-On-LAN network adapter to support this
feature. Some computers that support the Wake-On-LAN technology may have re­mote wakeup disabled in the BIOS by default. Before Client Manager can wake up
a remote computer, you will need to enable this option in the BIOS configuration of
each remote computer.

Displaying the Properties of a Client Computer

You can display the properties of any discovered client computer even if you cannot
otherwise access the computer because of access limitations or Unavailable status.
If you display the properties of an unavailable computer, the properties are read
from a database in the Windows registry on your computer. Since the Operating
System information is not stored in this same database, that information is not avail­able for a computer with a status of Unavailable. Remember that some items may
not be current if the properties have changed while the computer was off the net­work.

Understanding the Computer Status Icons

When you open the Select Computer dialog box, each computer in the list displays
an icon indicating the current status of that computer . The table below describes the
seven states a computer may be in.

Unavailable The computer is currently in a powered-down state.
W akeable The computer is currently in a powered-down state but sup-

ports Remote Wakeup technology.

W ake Pending A temporary status (not to exceed five minutes) while Client

Manager attempts to wake up a computer . (A computer that is
in the process of booting without having received a wakeup
instruction is listed as Unavailable, not Wake Pending.)

Normal The computer is operating within normal tolerances.
Warning A computer that has exceeded a warning tolerance level.

For example, the PC Health indicator can be configured to
display a warning icon if a hard disk is running low on space.

Critical A computer that has exceeded a critical tolerance level. For

example, if the hard disk is running critically low on avail­able space, the PC Health indicator displays a critical icon.

Desktop Management Interface (DMI)

DMI Utility

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.

VI. SOFTWARE REFERENCE

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 AUT OEXEC.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 DMICFG.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 DMICFG.EXE.

4. Type

DMICFG and press <Enter> to run.

The ASUS CIDB Chassis Intrusion Sensor Module

The optional ASUS CIDB is a module for providing audio alarm and logging when
there is an intrusion into the chassis of a computer system. The module detects a chas­sis intrusion by either light striking its photo sensor or by contact when its switch
connectors are shorted by chassis-mounted momentary toggle switches. An intrusion
memory function allows detection by BIOS and LDCM v3.3 on the next bootup.

Using the ASUS CIDB

1. You must have an ASUS motherboard with a chassis connector.

2. Connect the CIDB directly to the chassis connector or use the provided extension
cable and mount the CIDB to the chassis using a double-sided foam adhesive tape.

CAUTION! The CIDB component pins and metallic points must not come in

contact with another metallic surface or else shorting will occur!

3. Check the hardware settings:

• JP1 jumper should be enabled to use the photo sensor

• MS1 and MS2 connectors should be connected to momentary toggle switches

mounted on the chassis to use the contact method for triggering alarms.

• SW jumper should be enabled to allow the hardware monitoring compo-

nents to receive signals from the CIDB.

4. To stop the alarm from sounding, use the LDCM v3.3 software or place a jumper
on (or short manually) the CLR jumper momentarily.

5. If you have an updated BIOS with intrusion support. Booting the computer
after an intrusion will require a password which is configured through BIOS.

ASUS CIDB Additional Considerations

1. All motherboards with CIDB: If there is no power to the motherboard (i.e. re­moving the power cord or turning the power supply’s switch off) the alarm will
not sound but the CIDB will still memorize an intrusion event which BIOS and
LDCM will detect on the next bootup.

2. Motherboard with chassis intrusion components: Photo sensor, switch, and
memory will not operate with power removed. Power is required to send a signal
to the motherboard’s intrusion memory and buzzer. When using the CIDB on
these motherboards, all the CIDB functions will be disabled, the motherboard’s
intrusion components must still be used. The CIDB can benefit these mother­boards by providing a chassis switch which will operate even when the power is
removed. Pins [2-3] of the SW jumper can be used for a momentary toggle switch
and the CIDB’ s battery will be used to send an intrusion signal to the motherboard’s
intrusion memory.
